[Elecraft] No power out all of the sudden... :(

[Brett Howard]

Ok so we're out at field day and all of the sudden I heard a somewhat
strong signal and then all the receive has gone to low S Meter numbers
yet the radio is not deaf at all.  

Whats worse is that I am getting no RF out.  Pressing tune the radio
draws about 2.3A and displays -- for the SWR.  When tuning I get -- for
the SWR as well.  In tune mode the power out at the bottom shows 0W.
When hitting tune it says 5.0W at the bottom and shows 5W on the bar
graph but it ends up doing a full search to try and find a match and
never finds anything cause there is no SWR shown.

I've done a full parameter reset and have reloaded my parameters from
before field day.  No such luck.

Any help would be GREATLY appreciated!
