Gentlemen I'm not sure if this is the right forum but maybe someone has some
ideas.
I have a Icom IC-775DSP. Over the Sweep Stakes weekend it blew up an hour into
the contest. The cause of the failure was the same as the failure I had last
summer; one of the output power transistors blew when I change bands and hit
the tune button.
It appears when going from one band to another then hitting the tune button the
tuner is in a state causing excessive current to flow to the power FET's
causing failure.
I've heard of tuning for maximum smoke but two failures like this getting
expensive.
If anyone knows of a mod to prevent this from happening again I'd appreciate
it.
73,
John
