Re: receive works great, but no trans power, #ubitx-help
We have had a couple reports of Q90 frying, but not the mixer.toggle quoted messageShow quoted text
Perhaps as Gordon notes, these were due to a strong VHF signal.
I believe Gordon has suggested in the past the the failure mode might be
due to reverse voltage at the BE junction, not forward current.
I have no idea if the back-to-back diodes would significantly contribute to the spurs.
Doubt it would cause trouble where I'm at, as there are no strong local broadcasters.
I should try it, include a strap to remove the diodes if curious about some new spur.
We've got plenty of electrical storms.

It the signals are strong enough to fry Q90 the mixer will soon be gone too.
