Hi All
Thsi happen to me several times now.
Been trying to work a dx staion split, and listen to to second receiver to find
out where he is working the stations. I do turn off the second receiver, and
turn it on again. But after doing this a few times, there is no sound anymore
from the second
Hello Folks,
Just talking to a friend that has a K3 also and he was asking why the
signal gets louder with less noise when you turn off the AGC ? I turned
off tha agc when working a weak DX station, and he was right. Made the copy
easier and much louder. What is the technical reason for this?
Kieth is correct if the AGC parameters are set high, particularly the
slope - that tries to make everything the same volume. If you can
recall tuning an AM radio between stations, the noise level between
stations gets louder because there is no signal to hold the AGC active,
and the AGC is
Bud,
Depending on your soundcard you should be able to turn
off the monitoring so you don't need to change the
Line In level. For example, with the SoundBlaster
Audigy 2ZS, open the Recording Control (input mixer),
click the Advanced button on the Analog Mix input and
select Record
I am glad it works. It is a pity it is so large though. I would love one but
22ft! or 6.7m in diameter is a little too big for normal UK lots. I was
wondering if designing a reduced size version for 10m 6m and 4m might be a
good plan.

Is this something that just happened, or has it possibly always been
there unnoticed? In any case, a change to the BFO frequency of one or
all filters is in order.
The condition should be cured by doing a filter alignment. I highly

I just did that to catch your attention (sorry if anyone is offended).

OK, now this is weird. I went back into the menu after checking the manual
