K3 beta-test firmware AGC issue and test request (rev 3.03)

If you load the latest K3 beta firmware (3.03), you should set
CONFIG:AGC DCY to SOFT, temporarily, even if you weren't planning to
try the "soft-decay" feature. At present, setting AGC DCY to NOR will
result in excessively fast AGC and higher noise.

We'll be updating the beta firmware as soon as this has been corrected.
Meanwhile, please do try the "soft" AGC on pileups, if you get a
chance. In our lab tests, AGC-related in-band IMD (intermodulation
distortion in the presence of multiple signals) was reduced by 10 to 20
dB.
