Hans,
Thank you! That is a LOT of work done in quick time on top of all the rest that you have going on. I really appreciate the frequent updates.
That said, yes, you do have a few more things going on yet.
* CW is still not usable on -004 now because the receiver is listening 1.5 kHz lower than it's transmitting. CW-R is now not doing anything that I notice: Both transmit and receive frequencies do not change (aside from that fixed 1.5 kHz offset) and the sideband does not change. All bands.
* The receive BPF does not switch to a newly selected band until you toggle the tuning but the LPF filter now seems to be recognizing the shift (Thanks!).
* Attempting to change bands after a filter sweep if you start on 40m seems to lock it up still however now I can work it all fine if I start at 30m. (Getting there!)
Much better behaved now.
I shall do more exploring and poking about now. Fun stuff (for me, at least)
