[Elecraft] XV144 - power out with no drive

[David G4DMP]

Magic! I have just read your advice to Stewart GM4AFF and recognised a
phenomenon I have been getting with my XV144 for years. I had assumed
that the flashing LEDs were due to my fault in overdriving.

I have just added a 0.1 across E & C of Q7 and that has cured the
problem.  I must now do the same with my XV70.

Am I to assume that this mod has now been incorporated in new XV---
kits?

I am ever thankful to you, Don, for your valuable contribution to the
reflector.
