[Elecraft] AGC behaviour

[Enno, PF5X]

Hi all,

My K3 #1263 was delivered in July with F/W MCU 2.18 DSP 1.84 and I was
really enjoying the RX capabilities of the K3. Now that I have upgraded to
2.38/1.90 I believe the RX is more "restless" when listening to an "empty"
space on the band. The S-meter is constantly on S5 with pre-amp ON and S3
with pre-amp OFF on the lower bands (30/40m). I have compensated that a bit
by lowering the AGC threshold (from 5 to 4 now).
I liked the initial F/W wrt AGC behavior better (less fatiguing to listen
to).

I have read in the F/W history file that changes to the AGC have been made
from F/W 2.22 onwards. So I wonder if other people have the same experience.

I live in an urban area so it IS noisy out here. It is just the way the K3
deals with that noisy background level.
When switching to ANT2 (not connected to anything) the RX goes virtually
silent.
