Hi Alan,
yes, this is a really nice project. It's been here for a while and now I've finally started with the construction.
I started with the audio amplifier and built the RX up to the VFO. It seemed difficult to me to test the intermediate stages one by one, so I built the RX completely.
The VFO works and the frequency range can be adjusted exactly. The signal is clearly audible in the station receiver. But the signal levels are too low. You can already hear CW signals in the loudspeaker, but when adjusting the RX input filter there are strong whistles in the RX. Probably another problem in the RF amp area.
But first I have to find the error in the VFO stage.
Anyway, first of all thank you for your contribution.
