[MRCA] 10-Meter FM

[mac]

All,

That little video has sparked a lot of interest.  Great........

The SCR-808/828 and Russian R-108 (seen in the video) can also be  
added to the list.  Uncommon, though.  Also, the BC-659 is not easy to  
get on line.  Used a special battery (3 separate voltages) as part of  
the AFC circuit which is now unobtanium, of course.  I've come up with  
a work-around that performs reasonably well, details on request.  We  
mostly use 29.4 and 29.6 MHz  out here.
