K3 beta-test firmware revision 3.68 (with DSP rev. 2.49) is now
available.
This revision primarily affects those who turn AGC off. In the
previous beta release (3.66), the new AF output protection feature was
a bit too aggressive in the AGC OFF case, causing the audio output to
occasionally become muted. The threshold has been moved up so that
this shouldn't happen.
If you turn AGC OFF, you should also set up the AF limiter (CONFIG:AF
LIM). (This limiter has no effect when AGC is on.) Recommended values
are 18-24. Some experimentation will be necessary due to differences
in headphones and user preference.
Please send any questions to k3supp...@elecraft.com. For instructions
