Hi Ludwig
Thank you for your help.? I have been away for a few weeks but now back and with a new probe.? However the new probe didn't tell me anything more that I had already found BUT I did find IC503 (74ACT08D) had slightly different output levels to the FET gates (along with the weird waveform).? I replaced the IC and now have power output on all bands!? The drive waveform to the gates is now much better.? I'm going to look at the filters now and fiddle with the toroids to see if I can get a more consistent output across the bands.
Now there is just the insensitive receiver.? I can read signals from 3uV upwards but the audio is quite noisy.? The 3uV level is consistent across all bands so it is something common after the filtering.? I tried a linear power supply but it made no difference.
Regards & thank you again.
Greg
