Re: Digital BFO Mod: Terrible Audio! #bitx40help

Yes, his numbers are off.
Filter passband on the Bitx40 is around 2000 hz wide,
3 dB passband might be 11996000 to 11998000, within a khz or so,
depending on which bin the crystals for his rig were picked from.
BFO is probably best placed maybe 500 hz beyond that,
so 11995500 for USB and 11998500 for LSB.

I'm not sure what your frequencies mean. 11994420 - 11984800 = 12000
and 11996450-11984800 = 9620.
