[Elecraft] New Output Power Issue

[Ian Kahn - Ham]

Update on my low output issue:

I ran the TX Gain Calibration this morning, and everything passed with 
flying colors.

I am seeing about a 4-4.5V drop across the radio when going from rx to 
tx.  Rx voltage sits at 13.8V, but when I transmit, voltage across the 
rig drops to between 9 and 9.5V.

All tests performed while tuned into a 300W dummy load.

Before I tear into my rig and start looking for corroded tin pins on the 
PA board (K3 #281, so unlikely the board was replaced/mod performed), is 
there anything else I should test while my station is still all together 
in one piece?

Thanks to everyone for the assistance, and Merry Christmas!

73,

--Ian
