The same can be said about your Transmitter, John.  813's, 250TH's, 
modulation transformer, filament transformers, the homebrewed 
WA5BXO/K4KYV 43Hy Choke... and all that other stuff that survived the 
mud/flood of 1998...

the whole rig is a testament of your electronic repair skills, and 
knowledge of same.

Merry Christmas, my friend.

hey, if your computer shop isn't open tomorrow, perhaps you can go get 
on the air, and show that rig off.

I'm hearing rumors that 'Heavy Metal Ralley' nite is coming up this 
Friday evening.  If Paul/VJB or someone else could confirm, then perhaps 
that'd be a nice evening to get on the air.. the night before New Years Eve.

Just a thought.

Perhaps there won't be the same 3 or 4 guys who are talking about 
spending $200 to fix a rig that wasn't worth $20, twenty years ago ;-)

73 = Best Regards,
Merry Christmas
