Do you have a schematic for the XV222? I looked on their site and
could not come up with one.

Mark,
Sorry about your failed effort. There is little in the RX path other
than Q3 and U1 that is not also used in TX.
If you have equipment that can do signal tracing at 222MHz, just trace
the signal path. There should be a significant increase in RF voltage
at the output of Q3 and more
Doug,
This is one of the problems with using info from the wayback machine.
That was one initial 'cure' that worked only marginally.
Elecraft released a mod kit that works well. Put the parts from the kit
in, and yes, C180 is to be removed in the process.
Go back to setting L34 for best S/N
Tom,
I would say 100 feet if you are running 100 watts. If you increase the
power, the distance should be increased. As is often said in cases like
this 'it all depends'.
I am assuming you are using the OCFD as a receive antenna. If you hear
the COR clicking while transmitting, they are
Mark,
Replacing those components will normally restore receive.

My XV432 worked just OK as usual.
Barry,
That can happen if you ran CAL PLL with the bottom cover off. Try it again.

Doug,
If you have the most current upgrade kits, there is no overlap. OTOH if
you have older upgrade kits such as the BFO upgrade, there were changes.

It takes 20+ watts to tune the KAT500.
I have no idea of how to set up the IC7300 to do that when in SSB mode.
You will have to ask on the Icom forums.

Andre,
Do you have any power control? To check set the power to about 50 watts
and do a TUNE. Measure the actual power output with an in-line
wattmeter and a 50 ohm dummy load.
If it still goes to 160 watts, you do not have any power control. The
usual reason is the diodes D16 and D17

I suspect that artifact is being introduced by the Speech Processor on
the KSB2 board.
Do you know any locals who have a K2? The quickest way to verify my
suspicion is to swap out the KSB2 board.
BTW - TUNE switches to CW even if in SSB mode.

Joe,
The telling answer is in your statement "the radio has an internal ATU".
The radio is showing the SWR between the radio and the ATU.
The wattmeter is showing you the SWR after the ATU - in other words, the
SWR of the untuned antenna. So there may be nothing wrong.
Connect a dummy load
David,
As someone else suggested, it sounds a lot like RF feedback on 17m.
Try operating into a dummy load to see if the same thing happens - if
not, get out the ferrites.

That was the goal, but consider that the fires may have impacted the

Shipping one on the last day of the month meets the qualification.
Be patient until Eric updates us.
Stay safe, and if you are in the Western states, stay away from the fires.
