[Milsurplus] ATD

[WA5CAB at cs.com]

This mention of the ATD reminds me that I have what may have been an NOS ATD 
dynamotor and mounting plate (when I got it, it was dirty but still bolted to 
what looked like the bottom of the original crate).  And I have a few of the 
connectors left from years ago when I scrounged some up for Charlie.  And the 
manual, of course.  But the tuning units are all long gone (except for the 
GP-7).
