Is your NB on? If it is, turn it off and see if it helps.

I have used the solder blob method with success. However, when I was

Interesting. I built my K2/100 about 17 years ago and the fan has always
drawn air into the cabinet and exhausted over the heatsink. So, I rechecked
the manual and disassembled my rig to check for proper assembly. Fan label
is facing out and wires are soldered to the right pads(red=+, black=-).
I received my K2 as a 50th birthday present 15 years ago. It came with the NB
and SSB modules. What a surprise and what fun it was to build. I later did
all the mods and added the audio filter, 160 meter module, KPA100, and
KAT100. It is still the main radio here and gives me a thrill every time I

Peter,
I am assuming that you are using a K3. On my K2 I use a headset. I have a
hand key and a set of paddles hooked to the K2. On SSB I merely depress the
hand key or the dot paddle to key the transmitter. Don't know if this works
on the K3.

I think Don, W3FPR, answered your question. FYI, My K2 and SSB is a fairly

Never had a rig that had 160M on it until now. Still don't have a 160M
antenna. But after listening to the CQ160 CW contest for a while I had to
try. So, hooked my KX3 up to my 80M double bazooka. The KX3AT loaded it up
and I just spent two hours having fun on 160M. 15 contacts and 13 states
with
magnet and a narrow notch at the SO-239 jack and solder lugs to directly
connect the SO-239 jack to the outer surface of the shield. If you have
all those, there should be no change in the K2 behavior when installing
the KPA100.
