Power output down, red (TX) light flashing

Hi
Together with Marko, S54AM we are struggling to identify the erratic behaviour of his mcHF. They appeared suddenly after years of normal use, after latest FW upgrade.
The simptoms:
Power ON procedure - OK
Receiver - OK
Transmit - OK (with nominal power) for a couple of seconds than power goes down and RED (TX) LED is flashing maybe another 2 seconds after end of TX.
When restarting (Power OFF / ON) the simptoms start to repeat as listed above.
Any idea?
Kind regards
Janez, S58J

Janez, maybe a starting point:
Look in the menu "Debug/ Exper. Settings" under "VSWR Protect.threshold". You can set this to "Off" if there is a SWR limit set.

Hi Thomas
Thanks for your proposal. Before doing that I have to tell you that the same thing happens with dummy load (SWR 1:1.0) connected.
Kind regards
