[Elecraft] K3 AF Limiter needs higher threshold

[Dave Hachadorian]

There was another Sprint practice on Friday night. Once 
again there were multiple loud stations calling.

This time results were very good with AGC off. I had the two 
K3's set up with headphones connected to the SPEAKER 
outputs, so I was able to foil the AF limiter by running the 
AF gain at a lower level. I put back to back power diodes 
across the 8 ohm headphones, and I could hear them give just 
a gentle little fuzz to the very loudest signals, nothing 
like the raucous created in the K3's AF limiter.

Just raise the threshold on that limiter, or provide a way 
to turn it off, and the K3 will be a first-class cw pileup 
rig, with agc off.
