Does this assume that the K3 mode is CW? On my K3, without the KAT500,
if I'm in SSB mode and tap XMIT, the K3 goes into transmit, but there's
no RF out unless I speak into the mic.

Here is how I tune with the KAT500:
1. Make sure the K3 tune power is set at 25W.
2. Select the frequency you are going to operate at.
3. Set the KAT500 output port by tapping the ANT button.
4. If you are using a KPA500 put it in standby.
5. Hold the XMIT button on the K3 to activate the K3 tune power.
6. The KAT500 will start tuning. You don't have to push the TUNE
button on the KAT500.
7. When the KAT500 finishes tuning Tap the XMIT button on the K3.
8. If you are using a KPA500, put it in operate mode.
9. Start having fun!

I am trying to help a friend understand auto tuning on his KAT500. Bear
in mind that I have not yet touched a KAT500, so I haven't been able to
play with it to sort this out. I'm just reading the manual. I am
biased by how the K3 ATU works, but from the manual, it looks like the
KAT500 works differently.
He is using the configuration in Figure 1 (all DB15 cables) with his K3,
KPA500 and the KAT500.
From my reading of the manual, one must tap the KAT500 TUNE button to
put it in tune mode, then apply RF from the K3. Does that mean that if
I'm in SSB mode on the K3 (my friend is almost entirely an SSB op), that
I must either switch to a mode like CW to do this, followed by key-down,
or use the TUNE (Hold XMIT) button on the K3 to get the required RF?
Then tap the K3 TUNE/XMIT button again to put the K3 back in receive?
That looks like 3 button pushes to do a KAT500 tune. Right? Or can the
required RF be supplied in SSB mode by just speaking into the mic?
Sorry, I know this would be easy if I could just try it! Thanks!
