Lots of talk about EME and testing systems. This was quite relevant as I have been playing with MAP65 over the last few days. I want to be able to monitor the 40-50kHz of 23cm where the JT65C activity is located.
MAP65 on 2m EME
My previous attempts at getting MAP65 to work have been unsuccessful. Recently I became aware that it was possible to use the SDR-IQ on the IF output of the K3 with SDR-Radio as the interface to MAP65. My attempts to get it to work were getting nowhere until I spoke to G4IDR. Dave talked me through setting it up. I had not spotted a small icon on the SDR-Radio screen. Once pointed out it was possible to start MAP65 and send data packets to it.
Tuning the K3 to the 144MHz beacon band it spotted and listed GB3VHF. Clicking on the display trace of GB3VHF produced a decode of the beacon.
After this I reconnected the 9 element yagi and masthead preamp and left the yagi pointed towards were the moon would rise in a few hours.
15 minutes after moonrise I came back to see a whole load of stations listed, including RRs and 73.
Several of the stations were obviously direct terrestrial signals from the nearer continent, but at least three were by moon reflection from their DT timing on the decoded display. All in all I was pleased with this result and I'm now looking forward to connecting to my 23cm Eme system and looking at how many signals I can decode on that band/mode.
