Hi- Just encountered problem, if I key the tx at high power fm/cw the rig shuts down momentarily. At half power it operates normally this only on 2M uhf/L ok. Ideas anyone? thanks & 73 Bob W7LRD
When I see this it's because the SWR is too high.

Bob,
The IC-910H is very sensitive to voltage drop from the power supply. Icom recommends that the power cable be no more than 36 inches long and is of a heavy gauge. Not sure what you are using for a power supply - my IC-910H works best with a 35 amp Astron Linear supply.

Bob, some time back I had this same thing happening with my TS2000 on 6m. People told me it was rf getting into the radio. Nope. Turns out, the radio is somewhat voltage sensitive and so when I eased it up to 13.7v, problem solved. YMMV 73s
