Shortwave Radiogram, 10-14 August 2023 (program 317): Digital modes made of the finest polyester

In last week's email I mentioned that our transmission Tuesdays at 1430-1500 UTC on 9955 kHz from WRMI Florida has been bumped in favor of RAE Argentina al Mundo in French, which is Monday through Friday in that slot. However, Jeff White and WRMI has kindly given us the same time on Sundays on 9955 kHz. This should be more convenient for many listeners. This time of year, 9955 (160°) is heard best in parts of the southeast USA and into the Midwest, and, of course, in the Latin America target area. In autumn and winter, this frequency will reach farther at 1430 UTC. You might also hear some Cuban jamming on 9955 kHz, but this rarely complicates the decoding of our MFSK modes. Last weekend, Friday at 1300-1330 UTC, 15770 kHz from WRMI Florida, the previous week's program (315) of Shortwave Radiogram was broadcast. I uploaded program 316, but my old brain was distracted by household activities, so I failed to complete step two, which is changing the name of the file when it reaches WRMI. If you missed program 316 because of that error, Scott in Ontario made himself available Monday at 0800 UTC for this video (from which you can decode). Also "studio" audio is available here. The video (mentioned above) of last weekend's Shortwave Radiogram (program 316) is provided by Scott in Ontario. The audio archive is maintained by Mark in the UK. Analysis is provided by Roger in Germany. Here is the lineup for Shortwave Radiogram, program 317, 10-14 August 2023, in MFSK modes as noted:  1:43  MFSK32: Program preview  2:49  MFSK32: Does relaxing paywalls help digital news?  7:15  MFSK64: Solution to the problem of polyester recycling?* 12:06  MFSK64: This week's images* 27:51  MFSK32: Closing announcements Please send reception reports to radiogram@verizon.net And visit http://swradiogram.net Twitter: @SWRadiogram or https://twitter.com/swradiogram (visit during the weekend to see listeners’ results) Facebook group: https://www.facebook.com/groups/567099476753304 Shortwave Radiogram Gateway Wiki: https://wiki.radioreference.com/index.php/Shortwave_Radiogram_Gateway

Shortwave Radiogram, 3-7 August 2023 (program 316): Digital modes made from moondust

Listeners have noticed that our transmission Tuesday at 1430-1500 UTC on 9955 kHz from WRMI Florida -- usually difficult to receive during the summer -- has been replaced by other content. Today I received confirmation from WRMI that the French service of RAE Argentina al Mundo has taken over the time slot Monday through Friday. However, WRMI says that Shortwave Radiogram will get 9955 kHz Sundays at 1430-1500 UTC, eventually. Also today, Your Host (YH) informed us that This Is A Music Show (TIAMS) will discontinue its run on WRMI. TIAMS was a pioneer in the use of MFSK text and images on an analog shortwave carrier. Listeners are expressing sadness that the show will end.

Shortwave Radiogram, 27 July 2023 (program 315): Some history the building that has been VOA's home since 1954

Today, the temperature here in northern Virginia reached 97°F / 36°C -- which is mild compared to hotter weather endured by some of our listeners. Of course, our downstairs air conditioner (heat pump) decided to break down. Two HVAC guys looked at it, each spending about three hours, totally perplexed, trying a host of diagnostic procedures. Finally, it was fixed, but we were warned that our 18 year old heat pump is inefficient and probably won't last much longer. I was dealing with that crisis and also writing my monthly column for the North American Shortwave Association (NASWA). In accordance with the Parsimony Principle, I decided to use this column -- usually available only to NASWA members-- as the text content for this weekend's Shortwave Radiogram.    The subject is the plan for the Voice of America and its parent entity the US Agency for Global Media (USAGM) to move from it present headquarters building in Washington by 2028. The building on Independence  Avenue SW that is now home to VOA has an  interesting history. It was completed in 1940 and was intended to house the Social Security offices, but offices related to the war effort moved in instead. Most VOA studios were in New York City during World War II, but VOA moved to Washington and to the building on Independence Avenue SW in 1954. There are more details about the building, which you can decode from this weekend's show. A video of last weekend's Shortwave Radiogram (program 314) is provided by Scott in Ontario.

Wide-band noise near our 15770 kHz transmission

I usually listen to, and decode, Shortwave Radiogram via a few SDRs in various parts of the world.

On Friday, 21 July 2023, our broadcast at 1300-1330 UTC on 15770 kHz from WRMI Florida had "company" in the form of a wide-band signal centered on 15755 kHz.

This is how it looked via an SDR in Ireland ...

You can see the WRMI signal at 15770. Splatter from the wide-band signal caused interference to Shortwave Radiogram. Fortunately, Shortwave Radiogram can be received and decoded using AM, LSB or USB. In this instance, use of USB allowed successful decode of our MFSK.

I tuned to the same broadcast using an SDR in South Australia (16000 km from WRMI) ...

You can see that the wide-band signal was even more intense (and thus reached half-way around the world). But, again, use of USB allowed a successful decode of the MFSK. The MFSK traces on either sideband of 15770 kHz are faintly visible.

Despite the nearby noise, and with the help of USB to escape the noise, all of the MFSK32 text (120 wpm) and MFSK64 text (240 wpm) decoded, as well as all ten images, via the Australia SDR.

Michael Renner in Europe was tuned to the same signal. He tweeted (X'ed) about his reception, including audio of the noise on 15755, with my opening announcement in the background. Use this URL: twitter.com/dd0ul/status/1682375729713954816 -- preceded by https:// if necessary.

I don't know what the signal centered on 15755 kHz is, or from where it comes. It might be an over-the-horizon (OTH) radar system.

These wide-band signals seem to be proliferating on shortwave. How many such signals will fit in the limited shortwave spectrum?

Shortwave Radiogram, 20-25 July 2023: Digital modes from supercapacitors infused with espresso

We use Twitter @SWRadiogram extensively to share results of Shortwave Radiogram reception, and to send reminders about transmissions during the weekend. It is a simple and functional platform for that purpose. But, with uncertainties about the future of Twitter, I looked into Threads, the new competitor to Twitter. Establishing an Instagram account is prerequisite to getting on to Threads. I did that, and soon decided that Instagram does not interest me, for receiving or sending. I would just proceed to Threads. However, I learned that Threads does not, yet, have a desktop version. I don't do mobile, except sometimes as an internet radio, and to communicate with my wife. ("Where are you?" "I'm in the cat food aisle.") So I would just wait until Threads can be used on a desktop. A few days after signing up for Instagram, I received a rather stern notice from Instagram informing me that my account has been suspended. This is before I posted anything to Instagram or Threads. They mentioned procedures 1) to find out why the account was suspended and 2) to request a review of the suspension. I am not going to bother with those procedures. Threads will have to go on without me. I will stick with Twitter until it self-destructs, then probably exit social media altogether, and return to a unsociable linear website. Years ago, I had a Facebook account. I used it only to relay news about international broadcasting from my kimandrewelliott.com website (my @kaedotcom Twitter account is now my outlet for international broadcasting news). That Facebook account was also suspended, probably because I used a third-party app to push the website items to my Facebook page. So it seems that I've never met a Meta that will have me as a member. A video of last weekend's Shortwave Radiogram (program 313) (Friday 1300 UTC) is provided by Scott in Ontario.

Shortwave Radiogram, 13-18 July 2023 (program 313): Digital modes that bring snow to unlikely places

The slow browsing problem that I was lamenting last week has been resolved. I went into the Firefox settings and made various adjustments, applying the science (art?) of trial-and-error, and finally something worked. And so we move on to a new problem: My favorite email application no longer works with my email provider on one of my accounts. I can access emails, but through the provider's clunky email client. So more trial and error in the next few days. And in other technical news, my Sangean ATS-808 radio finally quit. Sangean gave it to me about 30 years ago in exchange for writing a guide to shortwave listening that was shipped with their radios. The ATS-808 had good sensitivity on shortwave and other bands, but it had no SSB capability. In recent years, it has been my kitchen radio (every kitchen should have a radio), used mainly to listen to our all-news station, WTOP, 103.5 MHz FM, in the mornings while making coffee and feeding the cat, and later in the day, while washing dishes and feeding the cat. For a replacement radio, I bought a Sangean HDR-14 (labeled SG-108 on my unit). I wanted to tune in to whatever HD (digital) sub-channels are available in the Washington DC area. Analog radio in the Washington area is not very good, at least not to my ears. The few exceptions include our public radio stations, as well as C-SPAN radio on 90.1 MHz, the all-news WTOP and Bloomberg Radio on 99.1 MHz. Tuning around on the HDR-14, I find that the HD stations are not much better. Many times the HD subchannel is used to relay a co-owned station that is available on another (analog) frequency. Among the bright spots on FM HD are Bluegrass Country, 88.5 HD2, and The Gamut, an eclectic oldies station on 103.5 HD3. There seem to be no local stations using AM HD. An interesting nearby station is WWFD in Frederick, Maryland, which is The Gamut full-bandwidth HD on 820 kHz -- no co-channel analog. I can't hear it from our house, but I do hear it driving around the suburbs. At night, the only AM HD signal so far detected is WPHT, 1210 kHz in Philadelphia, but the signal is not strong enough to establish actual HD reception.

Shortwave Radiogram, 6-11 July 2023, program 312: Digital modes that are 100% recyclable

This was a big week in our house. I installed a new Verizon Fios router, with the help of a Verizon representative on the telephone. We were FiOS (as it was capitalized back then) customers since it was introduced to our neighborhood about 15 years ago. We have used Fios for broadband and landline, but not television -- our TV is via antennas. Our new Fios router and plan is supposed to increase our downloads to 300 Mbps. This would be helpful given that my wife is usually working from home, our son is visiting for the week and working his aerospace engineering job from our house, and I, in retirement, am producing Shortwave Radiogram and scouring the internet for news about international broadcasting for the @kaedotcom Twitter (for now) account. That adds up to a lot of data in and out. The people in our house using wireless devices noticed faster connections from the new router. But I, upstairs, with an ethernet connection to bring the internet to my large tower PC, large display and full-sized keyboard (I refer to this system as The Mighty Wurlitzer), noticed that things are now slow. Very slow. Like dial-up slow. Images in websites loaded about as slowly as images do on Shortwave Radiogram. That slowly! This made for a long night last night, as I usually audition over 100 images for the 10-12 or so that are transmitted each week on Shortwave Radiogram. URLs and links had to be clicked a few times for the desired action. Over the weekend I will troubleshoot and configure the router, OS and browser settings. I'm already making some progress. Eventually I'll figure this out. Videos of last weekend's Shortwave Radiogram (program 311) are provided by Bobby in Louisiana (Thursday 2330 UTC) and Scott in Ontario (Friday 1300 UTC).

Shortwave Radiogram, 29 June-4 July 2023: Digital modes that promote daytime naps

As I type this, the Washington DC area is in a Code Red situation for the smoke and haze from the Canadian wildfires. Many of you in North America are in a similar situation. It does look hazy outside, but not as bad as our Code Purple a few weeks ago. With our temperature now 85F/29C, I would usually leave the windows open. But they are now closed to keep the bad air out. One of our news stories this weekend is about research showing that a regular daytime naps are associated with healthier and larger brains. On Thursdays, I am usually awake at about 3 am to produce Shortwave Radiogram, finishing at about noon. By then, a two-hour nap is obligatory, after which I start this weekly email. It's good to know my daytime naps may have a benefit. (I knew I would become a daytime napper in the year or two before I retired, occasionally nodding off briefly at my desk.)

Shortwave Radiogram, 22-27 June 2023: How to make a healthy potato chip

This week in northern Virginia, we have an unusual visitor: rain. It rained most of yesterday, and it will rain, at least a bit, during the next few days. This won't completely break our drought, but any precipitation helps. Meanwhile our sympathies are with our friends and listeners in Texas, enduring an extended heat wave. Other parts of North America, as well in Europe, will also experience heat waves during the summer of of 2023. Stay hydrated and find cool places.

Shortwave Radiogram, 15-20 June 2023: Nickel-based digital modes

Today in the Middle Atlantic, the weather is delightful (but we could use some rain). Shortwave propagation has been less than delightful, with static crashes from offshore storms adding to the mix. I hope conditions improve in time for this weekend’s broadcasts of Shortwave Radiogram, although our MFSK32 text enjoys a challenge. Our last transmission, Tuesday at 1430-1500 UTC on 9955 kHz from WRMI Florida, can be difficult to hear during the summer. Cuban jamming is also present on the frequency, probably as a result of certain programs now or previously transmitted by WRMI. That jamming seems half-hearted, so it rarely impedes the decoding of our modes. WRMI on 9955 is beamed at 160 degrees, but the antenna seems to propagate well off its back, which would be 340º. So for this troublesome transmission, reception might be good in Georgia, Tennessee, the upper Midwest of the USA, and maybe even into the Canadian prairies.

Shortwave Radiogram, 8-13 June 2023: Digital modes that pay no heed to the brightest cosmic explosion

I hope the fires, smoke and haze that affected much of North America in the past week have not had major adverse effects on you. I don't think they will impede our MFSK transmissions. Thanks to all of you who participated in last weekend's comparison of MFSK16, MFSK32 and MFSK64. My apologies for not tweeting my results during part of the weekend. On Sunday morning we discovered that our house had no internet access and no landline telephone, both provided by Verizon Fios. Attempts to fix it by way of self-troubleshooting and via the Verizon chat failed, so a Verizon technician visited on Monday. After checking all the systems, he determined it was a bad splitter in the Fios hub located a few blocks away. As part of the repair, he also replaced the Optical Network Terminal (ONT) on the side of our house, and the power supply for it, located in our storeroom. The new power supply no longer has a battery backup, so if we have a power failure, everything goes down. Anyway, during the internet interruption, I was able to tune in (via direct reception) and decode Shortwave Radiogram broadcasts (thus demonstrating the concept). But I could not tune in via remote SDRs, nor could I provide or receive updates via Twitter and email. The results of the experiments, based on your interesting reports, reminded me (because I had forgotten) why we don't usually include MFSK16 in our programs. MFSK16 is a robust mode in difficult reception conditions, but MFSK32 text succeeded almost every time MFSK16 succeeded. So we might as well transmit MFSK32. As for the images, I noticed a rather high failure rate among the preambles (triggers) of the MFSK64 images. This is probably because of the speed of their transmission. So I am considering using MFSK32 for the images, at least on a trial basis. The resolution of the MFSK32 images is fairly close to that of the MFSK64 images. (Images this weekend will be MFSK64.)

Shortwave Radiogram, 1-6 June 2023: Comparing text and image performance of MFSK16, MFSK32 and MFSK64

This weekend on Shortwave Radiogram, we will experiment with three flavors of MFSK: MFSK16 (60 wpm), MFSK32 (120 wpm) and MFSK64. We use MFSK32 and MFSK64 most weeks. MFSK16 is slow, but it is often successful in poor reception conditions. Bad reception can actually be useful this weekend, because it allows us to test the limits of MFSK16. One caution about MFSK16 is that the audio frequency must be tuned precisely. Generally, the RSID will set your Fldigi or TIVAR/Andflmsg to the correct audio frequency. If that does not work, adjust the audio frequency until a successful decode is achieved. In addition to comparing the text decoding performance of the three MFSK modes, we will also send the same image three times, once each in MFSK64, MFSK32 and MFSK16. You will notice that the image takes about the same amount of time to transmit in all the modes. The resolution of the images will differ, however: MFSK64 will be the most crisp, but also susceptible to interference lines. MFSK16 will be fuzzier but less degraded by interference. Here is the image in "studio" quality ...

Here is the lineup for Shortwave Radiogram, program 307, 1-6 June 2023, in MFSK modes as noted:   1:40 MFSK32: Program preview   3:08 MFSK16: Batteries, EVs and the environment   7:39 MFSK32: Batteries article continues 10:18 MFSK64: Batteries article continues 12:59 MFSK64: Image of Crimson Rosella (parrot) 14:40 MFSK32: Same image of Crimson Rosella 16:44 MFSK16: Same image of Crimson Rosella 19:16 MFSK64: This week's images 28:35 MFSK32: Closing announcements

Shortwave Radiogram, 25-30 May 2023: Unfazed by volcanoes

Daz Man in Australia has produced YouTube videos about the Shortwave Radiogram experiment with EasyDRF, May 11-16. See Part 1 and Part 2. Thanks to Daz for producing the EasyDRF programs, and the videos about them. As we approach the summer solstice, reception can be difficult on some of our frequencies that prefer paths of darkness. Examples would include the Saturday 2300 UTC on 7570 kHz and Tuesday 1430 UTC on kHz. Try them anyway.They are a good test for our robust MFSK32 text. Or visit SDRs such as kiwisdr.com/public/  to receive via more favorable locations, including the southeast USA for some of the WRMI frequencies.

Shortwave Radiogram, 18-23 May 2023: MFSK deploys again

Thanks to Daz Man in Australia for producing last week's special EasyDRF transmission. And thanks to everyone who participated by tuning and decoding, or attempting to decode, whether you were successful or not. When it worked, the EasyDRF results were dazzling: A fully formatted web page with links and animation, and no text errors. Also, images that were perfect, not fuzzy at all, and larger than our typical MFSK images. (See results in California at the bottom of this post, and more at @SWRadiogram on Twitter. EasyDRF is derived from HamDRM, the amateur radio version of DRM (Digital Radio Mondiale). Like broadcast DRM, EasyDRF produces results that are perfect -- or nothing at all. Thus, in typical shortwave conditions, where our MFSK might drop a few characters, and the images might be slightly to moderately fuzzy, EasyDRF may not work. For this reason. we will stay with MFSK32 and MFSK64, and occasionally other modes, on Shortwave Radiogram. Experiments with EasyDRF should definitely continue, in separate time slots. It will work well on shortwave paths where reception is usually good, e.g. UK to western Europe, or southern USA to the Midwestern USA and Canada. And it would be great to try EasyDRF on AM broadcast radio. Do you know of a local AM station that would be willing to try some experiments? Of course, EasyDRF would work on FM broadcast radio, as well. A video of last weekend's Shortwave Radiogram (program 304)  is provided by Scott in Ontario (Friday 1300 UTC). You can decode the EasyDRF from the audio of his video. His reception allows for the successful decoding of the html and all but the last two images. Analysis is prepared by Roger in Germany.

Shortwave Radiogram, 11-16 May 2023: EasyDRF special (you will need to install software)

I am sending this preview of program 304 (11-16 May 2023) a few days early to give you time to download, install, and practice decoding the EasyDRF we will be using.

EasyDRF is a version of HamDRM which can be decoded using software developed by Daz Man in Australia.

Program 304 is a repeat of Shortwave Radiogram 300, but in EasyDRF. Details of program 300 are here.

The EasyDRF software works in Windows and under Wine in Linux. See Daz's downloading and operating instructions below.

The sound is different from MFSK. Easy DRF is more of a constant buzz. Shortly after the buzz starts, the file SWRG-300-00.html will  appear in the Rx Files subfolder. Open that html file and watch the images populate it, one by one, during the half hour – reception permitting!

If you want to practice decoding EasyDRF before actual radio reception, the audio file is available here:

https://storage.googleapis.com/dazman/misc/2023-05-06-EasyDRF_Radiogram-v06-ODC-EQ12.wav

Important: If you decode from the downloaded audio file, delete or move the files from the Rx Files subfolder before decoding from actual radio reception.

Questions about EasyDRF can be addressed to Daz via Twitter: @DazDude4000, or email: dazdude(at)hotmail.com

Here are Daz’s instructions to install and use EasyDRF:

This EasyDRF version of Shortwave Radiogram program 300 can only be decoded with the EasyDRF Windows application program.

SOFTWARE

Website: http://homepages.ihug.com.au/~daz2002/tech/EasyDRF/

Installation: Download the executable file from the GitHub release directory. Create a new folder on the PC hard drive named "EasyDRF", and move the downloaded "EasyDRF.exe" file to it. That's all. (Do not create the installation folder in "Downloads", as this can cause security issues.)

AUDIO

Feed the audio into your PC the same way as for normal Radiogram broadcasts.

Options are: VB-Cable (SDRs), line input or microphone (analog radios).

NOTE: If using SDR# (SDRSharp), disable "antifading" as it can severely degrade data signals.

After installation into its own folder, start EasyDRF by double-clicking on the EasyDRF.exe file and select the correct input device in the Soundcard -> RX Input menu setting.

Check audio level using the Display -> Input Level menu setting. Adjust the receiver audio level to be near mid-scale on the Input Level graph. If the graph turns red, the level is too high.

Set the Waterfall display under Display -> Waterfall menu setting. Signals and noise from the receiver should appear on the waterfall display.

It's a good idea to make a recording of the broadcast in case of decoding problems.

AM-Sync demodulation is recommended, to reduce carrier fade distortion that can severely degrade data decoding.

DISPLAY

This Shortwave Radiogram program consists of a series of files, sent using EasyDRF. The entire program is intended for web browser display, for easy viewing. The HTML file is sent first. When the HTML file saves, open a new web browser window. Click the "RxFiles" button on EasyDRF to open the file save folder, then drag and drop the "SWRG-300-00.html" file into the web browser to display it. (You can also right-click on the "SWRG-300-00.html" file, then “Open with” browser of choice.)

The HTML page will open, and it will display stats on the received files in the top right corner. The page can be browsed while the files are still decoding.

Please include the stats in your reports (a screenshot), as the image quality does not change with radio conditions.

The images will automatically load into the page as they progressively decode and save. Automatic image loading stops after image 12 is loaded, or after 30 minutes. Images are enhanced for display using a custom SVG filter.

In most cases, only 51% of good data is needed for each file, due to RS4 error correction. If any files fail to decode, some images will be missing from the page.

Thanks for decoding the Shortwave Radiogram program 300 EasyDRF special broadcast!

Please send reception reports reports, as usual, to radiogram@verizon.net. Or report them to Twitter @SWRadiogram

Shortwave Radiogram, 4-9 May 2023: Digital modes the International Space Station should try to receive

Our transmission on Saturdays, 2300-2330 UTC, 7570 kHz from WRMI Florida, has been suffering from wide-band interference on the same frequency. The interference is intermittent: sometimes it's there, sometimes not, sometimes it lasts for several minutes, sometimes just for a few seconds. Anyway, Glenn Hauser, on his World of Radio program, reported that he was checking a shortwave frequency list, where he found "CGA984 - HF trading from Canada."  One of its frequencies is 7570. HF trading is high-frequency trading. The "high-frequency" does not refer to the spectrum from 3 to 30 MHz, although it does sometimes use HF radio, but rather to the fact it "uses powerful computer programs to transact a large number of orders in fractions of a second," according to Investopedia. Radio is faster than the internet or telephone lines, by fractions of a second, and thus provides an advantage to high-frequency traders. Benn Kobb provides this list of all the frequencies available to this HF trading operation, licensed in Canada and located in Harrow, Ontario, near Detroit. This would explain why the signal on 7570 is usually strong via SDRs in Michigan. This is what the noise looks like on an SDR. It doesn't look or sound like data, but there must be some method to this. I don't think that well-defined signal at 7558 is part of the HF trading operation, but I'm not sure about that.  

The FCC and Canada's CRTC will have to sort this out. We might experience noise on 7570 for at least one more weekend.

Shortwave Radiogram, 27 April-2 May 2023: Why Norway is having a spat with Sweden

The big solar storm of April 23/24 certainly had an effect on the Monday 0800-0830 UTC broadcast, 5850 kHz from WRMI Florida. The signal here in northern Virginia was weak and unusable. Via SDRs in Canada and Minnesota, I heard nothing. But I decoded successfully via SDRs in California, Colorado, Hawaii and Australia. The space weather maps showing a line across the United States, at about the north-south halfway mark, indicating where the aurora would be visible, were also good predictors of shortwave propagation. On April 25, we confirmed that WRMI has indeed reinstated our transmission at 1430 UTC on Tuesdays on 9955 kHz. The beam heading is 160°, nominally towards the Caribbean, but it is often heard many places in North America and beyond. The variability of propagation on 9955 kHz makes for interesting reception. A video of last weekend's Shortwave Radiogram (program 301)  is provided by Scott in Ontario (Friday 1300 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany. Here is the lineup for Shortwave Radiogram, program 302, 27 April-2 May 2023, in MFSK modes as noted:   1:39  MFSK32: Program preview   2:45  MFSK32: Swedish rocket crashes in Norway   5:37  MFSK64: The "strange blue asteroid" and its tail*   9:49  MFSK64: This week's images* 27:14  MFSK32: Closing announcements * with image(s) Please send reception reports to radiogram@verizon.net And visit http://swradiogram.net Twitter: @SWRadiogram or https://twitter.com/swradiogram (visit during the weekend to see listeners' results) Facebook group: https://www.facebook.com/groups/567099476753304 Shortwave Radiogram Gateway Wiki https://wiki.radioreference.com/index.php/Shortwave_Radiogram_Gateway

Hal Fi in California had no signal from our revived Tuesday 1430 UTC transmission, 9955 kHz from WRMI Florida, but he used an SDR in Georgia (USA) to receive these images ...

Shortwave Radiogram, 20-25 April 2023: Digital modes that heat the atmosphere of Saturn

I hope everyone has recovered from the Program 300 celebration last week.🙂 Now we settle into our pattern of MFSK32 text, MFSK64 text, and MFSK64 images. We find the MFSK32 and MFSK64 work best in typical shortwave reception conditions. And a definite advantage of MFSK is that the mode accommodates both text and images. If you would like to try other modes on Shortwave Radiogram, let me know. I recently received a reception report from a listener in China. It claimed reception on 9955 kHz, April 11, 1430-1500 UTC. I thought this might be a mistake, but I recalled Shortwave Radiogram was formerly on 9955. I checked the WRMI program schedule, and sure enough Shortwave Radiogram is on their System B schedule Tuesdays at 1430 UTC. So let's tune in Tuesday to confirm this. A video of last weekend's Shortwave Radiogram (program 300) is provided by Scott in Ontario (Friday 1300 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany. Here is the lineup for Shortwave Radiogram, program 301, 20-25 April 2023, in MFSK modes as noted:  1:37  MFSK32: Program preview   2:45  MFSK32: Saturn's icy rings probably heat its atmosphere*   9:15  MFSK64: Citizen scientists can hear the "sounds" of space 14:04  MFSK64: This week's images* 28:43  MFSK32: Closing announcements * with image(s) Please send reception reports to radiogram@verizon.net And visit http://swradiogram.net Twitter: @SWRadiogram or https://twitter.com/swradiogram (visit during the weekend to see listeners' results) Facebook group: https://www.facebook.com/groups/567099476753304 Shortwave Radiogram Gateway Wiki https://wiki.radioreference.com/index.php/Shortwave_Radiogram_Gateway

Shortwave Radiogram, 13-17 April 2023: Program 300. Let the celebration begin! OK, you can stop celebrating now.

This weekend is program 300 of Shortwave Radiogram. 🥳 This occasion will be mentioned during the broadcast, but no big celebration has been prepared. As usual, I finished this weekend's show just in time for my first deadline (upload to WINB), so I didn't have time to add much hoopla. The important thing is that I take this occasion of program 300 to thank you for tuning in, decoding, sending in your results via email of Twitter, and for your support of the broadcast. One scheduling note: WINB has moved the DRM transmission of Shortwave Radiogram to 15735 kHz, Friday at 1400-1430 UTC. WINB's DRM signal will be on 15720 up to 1400 UTC, then it will shift, more or less on time, to 15735.

WØMM in Houston received these images 8 April 2023, 2300-2330 UTC, on 7570 kHz from WRMI Florida. On this day, as happens occasionally, the broadcast was subject to noise from a still-unidentified source. The noise was bad in eastern North America, but not much of a problem in western North America, as can be seen in these images ...
