I've been playing around in the junk box and come up with this simple SSB transmitter and SDR receiver.
Here are a couple of videos.
The first is the TX.
The second the RX.
|WSJTX screen shot|
|Hybrid SDR and small 144MHz amp which drives the 400 Watt homebrew amp.|
|Screen shot of the EME chat after the contact.|
|The dustbin lid and LNB on a plastic pipe support|
|In the shed|
|Signals from QO100|
|A video of the setup.|
|The U3, filter and amp. 3 Watts of WSPR at first no success|
|The base loading coil, weather proofed in a plastic bag and flower pot!|
|Homebrew SDR with FT790 below. Heath Robinson but works well.|
|The screen WSJT-X and Powersdr|
|Some of the best DX received|
|The first JT9 630 Metre contact|
|Where the WSPR reached|
