I see this beat to death here but I have a question about peculiarities on this radio.

I have seen to adj the BFO first and MO last.  I have a very accurate HP counter referenced to 10 MHz stnd. Als a HP sig genrator.

I find if I set BFO freqs to within 1 HZ that unless MO is adjusted off of exact 20 MHz the radio is off freq on all bands. To get it on freq after aligning BFO I must tweak the MO away from 20 MHz to end up on freq.   I have always found MO freq wg=hen set dead on with other radios and BFO set correct the radio was on freq.  Guess I am asking too much from this radio design.

I remember seeing this on a corsair also years ago.  I also seem to see a difference between TX and RX freq.  Also the freq error changes from band to band I suppose caused by errors in the crystals for each band.

I tried setting MO for exact TX freq but then BFO had to be altered to get RX freq right. Seems like chasing a moving target.
