My FT 890 has suddenly stopped producing 100 W output. The best it will do is
around 10 W. It was performing normally and I was tuning into the 17 m band
using a rolling induction transmatch with an output of power of approximately
10W. I achieved a good SWR and listened for any activity and when none was
heard I tuned back to 20 m and tried to increase power, but I couldn't get any
better than 10 W output.
Thinking that I may have inadvertently tried to tune into a high SWR with too
much power and that the output power had been shut down to protect the finals,
I shut everything off and gave it a chance to reset it's self. When I turned
it on nothing had changed, still no output power. Following the manual I
performed a reset to the factory settings, which worked because my memory
selections and other personal choices were changed. However there was no
change to the power problem.
Does anyone have any suggestions how to rectify this problem, or is a trip to
the shop required.
Thanks in advance for your advice.
