The KX3 AGC is very similar to the K3 AGC. Take a look at the "Noisy
K3" article on my website for some relief. The KX3 and K3 threshold
and slope numbers may not match, but can be a guide for obtaining the
settings that are best for your type of operation.

I am going to sell my K2 as it is gathering dust since KX3 came on board. But
for probably the last time I put them on the A/B switch. Here is what I have
found.
1. K2 has good speaker. KX3 has lousy speaker. Nothing strange as K2 is
bigger.
For comparisons I attached KX3 to an external amplified speaker.
2. A weak CW signal in K2 is natural and easy copying. You can make it sound
similar in KX3 by playing PBT and sometimes engaging APF.
3. in SSB, K2 sounds nice and mellow although the bandwidth is limited. KX3
sounds tiring because of AGC pumping. I fiddled with HOLD, ATTACH, etc.,
with little effect.
K2 has to go because it is too big. But it is a fine radio.
Has anybody found AGC in KX3 harsh? Any way to do something about it other
than running RF gain?
