High SWR/Low Power out on K3S

[Dean Blair]

Hi,

Just curious if others had this issue and could resolve it.

My K3S had suddenly started showing High SWR faults with resulting low power out due to rollback even when the autotune reads 1.0-1.  Different dummy loads, antennas, and coax jumpers change nothing.  I upgraded the firmware to the most current release and still no change.

Any suggestions?

Dean,

It sounds like you have an intermittent connection somewhere.  Contact
K3support for the best analysis.

Loose connection between the so239 and the tuner board?
