[Elecraft] XV144 shutdown

[Wayne Burdick]

Pete,

After establishing the desired power output level, try turning off ALC (see owner’s manual; CONFIG:TX ALC).

If turning the ALC off eliminates power fade, then it’s a firmware problem. If this doesn’t help, then something is heating up, possibly a cold solder joint or component.
