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.
Captured this using my new SDR PLAY SDR and SDR console software. Very impressed with this low cost SDR. Will have more updates with it soon.
This one sounds familiar, however, I do not recall the signal being so wide in bandwidth and lasting this long. Another data transmission from an unknown source. this is a short clip of it on 13605 KHz.
Been hearing a lot of this over the last several months. Thought initially it was a stuck WEFAX transmission,. however this has been ongoing for too long for it to be that. Some type of data transmission.
