This is Santa Maria in the Azores working aircraft with frequency info and SELCAL.
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.
This is a redo, this time corrected with audio, BBC World Service from Ascension Island on December 5 approximately @ 0515 UTC.
Tonight, 10/30/2016, many Over the Horizon Radar Signals, OTHS, have been very active in the upper portion of the 6Mhz. band segment. This is quite unusual to find these here and with this amount of frequent activity.
Came across these while tuning around. They are definitely sky wave propagation because of the QSB. They appear randomly in this band segment. Recorded this using the SDR PLAY SDR with my OCF Dipole and SDR Console v3 software.
This is OK2RZ from the Czech Republic as heard here on 6/5/2016 @ 1945 UTC on 20m. He was speaking about a hail storm there. Some of the USA stations he was working could not be copied here. I was using ,y SDR PLAY RSP with my OCF dipole and SDR Console v3 software. I turned on the LNS, (Low Noise Amplifier), which did improve the copy of his station by lowering the noise floor some.
Many of you have been asking about the “Mystery” signal. Fear not, as it is alive and well and can be heard every night around midnight ET. You can find it lurking between 4700-4800 kHz. Here it is invading the frequency of a navigational beacon. I was using my SDR PLAY and SDR CONSOLE software with my OCF dipole.
Captured the tail end of a MARS training net on 6823 KHz. This was heard with my SDR PLAY RSP and SDR console software V3
AIR in poor band conditions. This was recorded using SAM mode on my ELAD FDM S2.
Using some new software for this recording. This is called SDR Sharper and it’s pretty nice. Lots of good features and easy to use. This is the Voice of Vietnam, using my SDR PLAY.
