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,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.
