We had good results last weekend, including another waterfall graphic provided by Merkouris in Greece (see below). As we approach the (Northern Hemisphere) winter solstice, the Friday 2030 UTC broadcast is now heard better in Europe. The Saturday 1400 UTC show… Leer más ›
We had fun last weekend with the waterfall spectrogram of the Arecibo message to outer space. You can access some video examples here. This weekend, Merkouris, who created Arecibo waterfall graphic, will tell us, by way of MFSK64 text, how… Leer más ›
Hello friends, The Mighty KBC’s new frequency of 11600 kHz, Saturdays at 1300-1400 UTC from Bulgaria, reached across the Atlantic last weekend. That included the minute of MFSK64 at 1330 UTC (see below). If you are in North America, try… Leer más ›
Hello friends,For anyone who was awake for last Monday’s 0800 UTC broadcast, sorry that it was missing. There was an automation issue at WRMI, which I hope is resolved by this coming Monday. The 0800 UTC transmission is interesting, because,… Leer más ›
Hello frends, The big news this weekend is that our Saturday broadcast on 9400 kHz will change its time to 1400-1430 UTC (it was 1600-1630 UTC). This should improve reception in Europe by keeping it in the daylight hours. We… Leer más ›
Hello friends, This weekend, I am trying Mailchimp to distribute the weekly email to Shortwave Radiogram listeners. If you no longer wish to receive these weekly notices, there is an unsubscribe link at the bottom of this email. Sorry about the… Leer más ›
Hello friends,Last weekend I missed all the shows. My wife and I were in Colorado visiting our son the graduate student. So I’m glad you sent in your reports, either via email or to the @SWRadiogram Twitter account. And thanks… Leer más ›
Last weekend’s slant test produced interesting results. Please note that your sound card might be perfectly calibrated, but slant in MFSK32 images will still occur. This is because of disagreements in the sampling rates of my sound card, the sound… Leer más ›
Hello friends, Thanks to everyone who participated in last weekend’s exercise to eliminate slant in MFSK images. Many of you did not see any slant to begin with. This usually happens with direct reception. But if reception is through an SDR,… Leer más ›
Hello friends,Sorry about the missing Shortwave Radiogram last Friday at 2030-2100 UTC (Brother Stair was heard on WRMI, instead). That was due to an uploading error on my part.
Hello friends, Last weekend was very difficult for Shortwave Radiogram, between the poor propagation and technical mishaps. Saturday at 1600 UTC, the transmitter in Bulgaria went off the air shortly after Shortwave Radiogram began. But it came back on… Leer más ›
Hello friends, Apologies to those of you who were tuned in to last Sunday’s 2330-2400 UTC broadcast on 7780 kHz. A few seconds after the broadcast began, another WRMI audio program came on and stayed for the rest of the… Leer más ›
Hello friends,Last week’s 20xPSKR63 was successfully decoded by some listeners, but for the most part the mode showed too many errors for typical shortwave conditions. The MFSK128 had better results, but it produced more errors than the slower MFSK64.
Hello friends, In addition to the SSTV images on his Slow Scan Radio broadcast, John Piek, PA0ETE, has been transmitting text modes, including the very fast 20xPSK63R In Fldigi you can find it under the PSKR Multicarrier op modes, although… Leer más ›
Shortwave Radiogram, 3-6 August 2018
Hello friends,Last weekend’s experiment with 8PSK-125F and 8PSK-250F was generally unsuccessful. This is despite improvements to the encoding and decoding of these 8PSK modes in Fldigi 4.0.17. Most listeners’ reports showed errors in the 8PSK text, while the MFSK 32… Leer más ›
Hello friends, I am no longer inserting images into these weekly emails because AOL Mail (which now maintains emails from the verizon.net domain) does not seem to like them. A good place to see decoded images and other results is… Leer más ›
