the CAL CUR setting up to 3.50 for either the QRP K2 or the KPA100,
and make sure the power supply voltage is 13.8 or greater under full
power transmit load.

I apologise if this has been asked before, but I have a newly developed
problem with
he speaker.
But before I start taking the hardware to bits, is there anything else I
have overlooked? I might add that I am running the latest firmware etc etc.

Lloyd,
Do you have the 2 diodes to permit using a hand key in addition to
paddles (auto-detect)?
If so, try removing the diodes to see if it works - Turn off auto-detect.
Do you have a microphone connected? If so, remove it on the possibility
that there may be a mic problem with the PTT
change our habits with using the receiver
controls in the future. Attenuation is still effective.

I agree with Peter in that many hams use too much RX RF Gain and too
little attenuation. Per one authority on receiver performance, th
Another complicating factor is whether you are listening in CW or CW
reverse.
I would think that the DPDT switch would be the best solution.

Think of it this way. Let's say that your default CW note tone is 500 Hz. When you're zero-beat
for an S-9 indication in the bargraph. Usually that value will
be between 23 and 19.

Thanks to Martin and Don.
Yep, the age setting had mysteriously advanced while in storage.
I had forgotten about the CAL submenu. Messing
to produce
no bars with no signal and an S-9 indication with an S9 signal. The
latter is normally set with the preamp turned on, but preamp off can
also be used.
We are in a sunspot low, so signals may not be as strong right now,
particularly on the bands above 30 meters.

replacement. The testing
should be completed in the next few days.
One ham with a similar problem wired an SMD J310 on the bottom of the
board with good results - if you cannot find a thru-hole J310, you might
consider that solution.

If using a dynamic mike you should not have any connection to pin #6
