[Elecraft] Question K3 ALC w/SPE Expert 1.3K-FA amp

[Guy Olinger K2AV]

I look at plus and minus 250 Hz. That's because any wider than that is in
the passband of someone up or down. AND, particularly since K3's, people
are starting to squeeze toward three operating spots in a kHz, rather than
two. Happens all the time. That's plus and minus 167 Hz. That matches the
"250" 8 pole roofer that is really 330.

73, Guy.
