[Milsurplus] Fw: MAB

[WA5CAB--- via Milsurplus]

I have to agree with Ray.  Working on a BC-611 is always a PITA.  Sometimes 
it's worse.

Speaking of MAB/DAV, if anyone is looking for the vibrator supply, some guy 
in NY has one advertised for sale in this weeks A.R.C. list.  No price 
listed.  Contact me for a copy of his ad.
