Good Evening,
The wind switched direction on Tuesday to come out of the east.
Within an hour I could see the smoke flowing through the trees. Then
ash started falling. Luckily the smoke did not smell like a local
fire. It was from a fire in the Gifford Pinchot Forest in Washington.
I did before shipping in for repair with a directional coupler. Looked great.

I guess to simplify it, It does pick the correct codec, it does not
recognize that you changed the name of the codec.
And I think this is probably getting way off topic for the Elecraft list

You need RF to cause the amp to know what band and freq you are using.
Keying then mic on SSB won’t generate RF until you speak. CW, AM, FM or RTTY
will generate RF when keying the mic (or tap the paddles in CW) and will
generate the RF to tickle the Amp and ATU.

The KAT500 retains matched memories for each band/frequency per antenna.
So yes, you have 3 solutions per band/frequency. It has quite a lot of

You would then leave the KAT500 in Manual mode and each time

Although it's preferable to have at least 20W to tune, the good book

providing that in CW mode. Have you 'trained' the KAT500 for the entire
band/s you want to use? If you do that in Auto mode, then switch to

With nearly all modern transceivers nowadays, the trick is to set the
power on AM to 25 watts (which is the most you should ever run a 100

carrier into the tuner at an acceptable low power.
You can tune it in CW mode, but

I own a KAT500 and KPA500 that I use with an IC 7300. When in CW mode, the
KAT500 can be activated by keying the IC 7300, no problem. This allows the
KAT500 to find a match with low power while the KPA500 is in standby mode. In
SSB mode, there is still the need to activate the KAT500 for the
