[ICOM] 7546 Pro II

[Tony Lord]

Hi all,

A question for you guys. I was testing out a new dummy load to see how
"good" it was, last night. I tuned to 20m and FM and left the rig on (into
dummy load) for about 10+ minutes, at full power. The dummy load passed the
test with flying colours! However, after the test, the Pro II was getting
rather hot at the back and then refused to transmit on SSB, it indicated
very high SWR's which I could not correct with the "tune" function. By this
time I was on main aerial and not the dummy load. So I did a Bill Gates,
switched everything off, waited a few minutes and then switched everything
back on and all worked just fine. Made a number of FB SSB contacts on
various bands.

Is there a heat sensor within the rig that stops transmissions until the
unit has cooled down?? Just for information the receive side worked
perfectly.
