[Elecraft] PA No worky...

[WILLIS COOKE]

Have you unplugged the board and inspected the connector pins at the back of the board, then reseated the board to be sure the pins are intact, properly seated and making contact?  I cleared a similar case of trouble in this manner.  I have seen pictures where the pins were corroded away and the connector required replacement.

Ok well I'll provide a bit more information.  I've pulled the PA and
taken a look at things and nothing looks like its gotten hot at all.
Nothing is obviously wrong at all.

I've checked all my filter settings (which hadn't changed since it was
working a few minutes ago) and they all still seem to be correct.  I
reloaded the firmware to the radio and also restored my previous
configuration.  I've redone the synthesizer configuration because I've
recently added the synth stiffeners.  I then redid the TXG
calibration.  5 Watt TXG calibration goes 100% successfully.  However
100W TXG Calibration results in an ERR TXG message.  It seems like its
doing everything that it should to make the radio produce 100 watts
but the PA just isn't doing its job.  Flipping between PAio ON and
PAio TST does produce a relay click so the PAIO is doing its job.  I
should also mention that all fan speed tests check out ok as well.

If I'm forgetting anything else to check please enlighten me.

Thanks much gentlemen
