[Drake] TR-7 Assistance

[Robert Wood]

Hello All,

I have been experiencing an unusual problem with my Drake TR7.  I am a CW
operator and use the equipment in that mode.  After it warms up for an hour or
few, the rf signal diminishes dramatically.  I do not believe it is related to
the audio amplifier, as turning up the volume increases hash.  If I momentarily
turn it off and back on again, all is well for an hour or two.  Recently I have
noticed I can also restore the signal by switching it to AM and back to CW.
Switching it between CW and the other modes do not restore it.  Any comments
will be greatly appreciated.

Thanks,

Robert Wood
