"Bill Carpenter" <[EMAIL PROTECTED]> made an utterance to the drakelist gang
----------------------------------------------------------------------
I installed the AC4R upgrade in my AC4 this week which is a very nice kit.
The T4-XB seems to love it and was working extremely well. I spent a couple
of hours on 160 SSB last night and made a few CW contacts with no problems
on other bands. This morning when I was tuning the transmitter on 80 I
noticed that in CW mode that the gain control suddenly had no effect on
power out. It goes from no power to full power as the control is advanced
at about 9 o'clock very suddenly. There is no gradual increase as there
should be. In tune and SSB mode it still works fine with the normal gradual
increase. Any ideas on how to begin trouble shooting this? I don't see any
obvious burned components - at least not yet. I'm hoping it's a tube and
not some hard to find component!
73,
