Hi gang,
My K2 (2631) with KSB2 doesn't transmit and receive on the same frequency.
There's about a 70Hz difference on lower sideband and 50Hz on upper. The
transmit frequency is always lower than the receive frequency.
Carrier supression is great, transmit audio sounds good, and I'm
Many thanks to all who answered, including those who helpfully suggested
that I might be using RIT or XIT without knowing it.
I just put a frequency counter on the BFO on my K2, and it changes about
70Hz when it goes from receive to transmit. Yeah, I know, there's not
supposed

Interestingly enough,
in the late seventies we were complaining about the lack of suitable outlets
for homebrew projects. I didn't dcompletely buy it then nor do I buy it
now.
It's always required ordering out for stuff like ferrites, power
transistors, and the like. It's not so bad,
Hi gang,
It's Merlin, W3ICT; you know, the guy who complains about the filter in the
KSB2 all the time. This time, it's actually something different.
Recently I had to replace the finals in my K2 (2631). In the process of
measuring forward bias, I accidentally lunched the SC1969s with
I'm pleased that the KDSP2 addresses the issues that limit the KSSB2's
performance. And yes, that is a common approach these days; have an
unspectacular
filter close to the antenna, and clean things up at audio with DSP. This
leads me to say two things:
We all know, or at least we
A few days ago somebody was asking who it might be who's been experimenting
with shielding on the KSB2 board. I was that guy I suspect, because nobody
else I've observed on this net seems to be as annoyed as I about the bad
skirts, high ripple, bad ultimate selectivity, etc. when the K2
I love loops. They're quiet, have lots of capture area, wide bandwidth, and
when big enough, don't have the big horizontal spikes that collinears or
other horizontal wire antennas have.
But here's my question: Does anybody know whether the stup on Radio Works's
superloop is open or
