Work In Progress

Small step forward - the receive/transmit switcher board is up and running.  My VNA shows only with only 0.06dB loss across HF frequencies,  which seems unrealistically good.  A brief check with the WSPR transmitter confirms it has no measurable impact on real world performance with my main antenna.

I got a 3D printed case for this which needed filing down to get the lid to fit, and will need some holes drilled for the indicator lights and some labelling of ports.  That will finish off the hardware components, other than plugging them together.  

After that will come setting up a Raspberry Pi to run the receive side of the system and make publish data to the internet.  My experience of embedded computers like this is it will either take 5 minutes and be a complete breeze, or hit some weird driver or compatibility problem and take 5 weeks of of pain to work out...

Then it's time for more antenna experimentation, and maybe packaging the completed modules together in some way.
