[Elecraft] K2 - Alignment/Test Part II

[Don Wilhelm]

JT,

No need to wait for the N-Gen for the Bandpass filter alignment - just 
initially peak the BPF in receive using only band noise (connect your 6 
meter antenna or just a piece of wire to the antenna jack center 
conductor).   Once you have the BPF peaked on receive (this is only an 
initial alignment to get things 'into the ballpark' - peak for maximum 
antenna noise), then do the Transmit BPF alignment.  It is easier to 
observe the peak during the transmit alignment, and when that is done, 
it will be correct for both receive and transmit.

The N-Gen will come in handy when you are doing the IF filter alignment 
(CAL FIL) using the Spectrogram display - for that process,  a broadband 
noise source is best - and the N-Gen is a broadband noise generator.
