Hi,
I've just done BFO alignment and freq. calibration on my K2
and have some
questions.
I can zero beat AM stations around 7130 kHz with +-10Hz.
1) BFO range:
High freq. = 4917.13 KHz (>= 4916.3 -> ok)
Low freq. = 4913.08 KHz (not <= 4912.7 !!!)
Range 4.05 kHz (>= 3.6 kHz -> ok)
Should I have concern about BFO low freq. is 1.1kHz too
high?
2) BFO alignment: I did not found any instructions on how I
should use filter
crystals frequency written on the bag. It is "3.6" in my
case.
Nevertheless I am able to get all FL1-FL4 into desired
range, using RF noise and
SpectranV2 on my PC. The pitch does not change when I toggle
"cw" and "cw rev."
Are my BFO alignment values ok?
