Thanks for the information. I did not have a tuner in this K3S when it failed the 6M cal so I figured it was just marginal for some reason since it DID pass on the third try. I have read the Config menu now and see how to check the gain and do a manual cal if necessary.
I was just afraid to do the Cal again with the utility since it did eventually pass. I thought...leave it alone. But I did want to investigate the 6M gain etc. and understand what it was all about. I see now that I can do a manual Cal on 6M only if it becomes necessary. I need to learn to read the pages on menus in the manual as well as the index. I checked as you suggested and my gains are LP 10 watts and HP 34 at 50.135 MHz. Also I did as you suggested and the dummy load tune SWR is 1/1.1 So all good I guess.

Just jumper the coil, L10 and it will bypass a burned capacitor. The trap was found to be redundant. Make sure 6m is on the correct antenna not 2. In TUNE, does it really have High SWR? Set ATU to BYP for any tests using dummy load. Make sure TECH MD is on, then look at config menu TXGN HP (or LP below 12w [8w 6m]) for the gain number. Try a manual TX gain cal on different parts of the band, every half a meg or so and see if it will pass. (set TUN PWR to nor, set power for 50w EXACTLY, then long press XMIT to send a carrier at 50 w for several seconds) Then check the TXGN number. You can do it at 5.0 watts exactly for the LP gain cal.
