I've been doing some experiments to improve the performance of the
antenna splitter. The one I initially tried from
http://www.qrp.pops.net/swl-ant-split.asp works but has poor bandwidth.
I have now substituted a trifilar would unun transformer on the input
feeding the Wilkinson splitter.
Both the Elecraft Hex Key and the Brown Brothers BTL-A paddles work great. I
like the stability of a paddle that has little or no vertical movement of
the paddle arms. The Hex key is heavy but the Brown Brothers is easier to

Have you downloaded the latest firmware? Perhaps this is an AGC
issue, where the pops and cracks from the QRN are louder than they
should be? The AGC has been recently tweaked...

There has been a lot of confusion about AGC in the K3. Some of it is
AGC related, some of it is AGC interaction with noise reduction (NR).
A later email will address the noise reduction issue. For now, let';s

Thanks for the explanation. As you say, noise levels differ between bands and
over time E.g. 80m in Summer compared to Winter or HF versus 50MHz and
higher bands via a transverter. Does the AGC setting apply per band or does
it cover all bands?
AGC also depends on mode, CW vs SSB bandwidths.
I see the same extra stripe using mixw and an RF generator. I had to turn
down the line out of the K3 to 001 and crank up the sound card to max
inorder to eliminate it. The level is a bit weak now and needs more gain.
There is something not quiet right here.

It already works on receive. Its in-line for both TX and RX. If you have
