Mac: I don't understand this. How badly is your BFO drifting? In MY experience with the 
BC-453 and/or R-23/ARC-5, the drift is un-noticable. 

I did hear from another user of a BC-453 on 630 meters that the BFO does drift enough to 
make receiving WSPR signals problematic, but he also mentioned that the drift in HIS case 
was due to line-voltage variations causing changes in filament voltage, and when he used 
regulated DC filament voltage, or even batteries, that the extremely minor drift he noticed 
was reduced.

I haven't followed up on that story, and this was a few years ago.

Yet YOU seem to be telling us that the drift you are experiencing is far worse than that.

Would you please elaborate?

When I used my own BC-453 on 630 meters, connected to my computer and using Spectran 
software, I didn't notice enough drift to worry about. But at that time I wasn't trying to receive 
WSPR or JT-9 signals either.

So, what, exactly, is going on at your place?
