Transmit Gain Calibration Failed After KSYN3A Installed

[Michael Raskin]

I KNOW this is cockpit error (it always is) so I’m hoping someone can tell
be what I am doing wrong.  I just installed the two KSYN3A synthesizer
boards in my K3 main and sub and successfully upgraded firmware to 5.14, and
performed the installation check:  SYN1 OK and SYN2 OK.  When I tried to do
the xmit gain calibration at 50 watts, this is the message I received:
“Xmit gain calibration failed because transmit power did not reach the
expected value.  50 watt calibration failed.”  I even tried it at 5 watts
and still didn’t work.  Yes, I cycled K3 off and then on after firmware
upgrade.

Did you attach a dummy load to an antenna port?  (Later to another port
for the flea power calibration.)
Did you tell the calibration program to use the port with the dummy load
attached?  (DOH!!!)

Hey, we've all been there.  It's best to ask the dummy questions first,
they're the simplest to miss.

Mike,

Are you using the latest K3Utility?
You can do the TX Gain Calibration manually through the menu.  Give that
a try on a few bands - if it is successful, try the K3 Utility process
again, or just do all bands manually.
The manual procedure does the same thing as K3 Utility, except the
Utility makes it 'pain-free'.

73,
