Some of you have been asking if the “Mystery Signal” is still on the air. Yes it is! Here is a recent clip of it mixed with some CODAR. I’m also trying out SDRUNO software for the very first time. Recorded on May 24, 2017 around 0445 UTC using my SDR PLAY RSP1 attached to my OCF dipole at 35′.
This is Santa Maria in the Azores working aircraft with frequency info and SELCAL.
Typical QSO on 40m, but this one was very good as it covered 2m and 70cm SSB operation and the use of a 1000 foot loop fed with ladder line.
PPE Time station from Rio De Janeiro Brazil – with male announcement every 20 seconds in Portuguese. Heard under WWV on 10 Mhz. in poor band conditions.
This is a Swahili broadcast from the Dole Region of Zanzibar. This was recorded using the SDR Play in SAM mode using a narrow filter due to RTTY interference.
English language broadcast with story of Romanian woman brain surgeon, then signoff. Good Signal.
All India Radio in with a big signal tonight on 9445 KHz.
This video is a bit different from my others. It is of a vintage Realistic DX-300 shortwave receiver, which was brought back from the dead. I had to replace the AC line cord, put in a new electrolytic filter capacitor and also replaced the burned out bulbs with white LEDs. This is a short video of it in operation. These receivers were from the late 1970s into the early 1980s and featured Wadley loop design.
