[Elecraft] Problem with Test TX Data and ALC

[Carl Jón Denbow]

Thanks.  Yes, everything's working now.  I guess my problem was the Line 
Gain at zero and not knowing how to adjust it.  Reading the manual and 
having you point me to the source of the problem were the keys.  Thanks 
again!  73 de Carl, N8VZ
