I think ya'll are all missing the point... the BC-610 has a twist-plug 
recepticle on the back of it  the blades are curved.  If one didn't know 
better, one might think that the BC-610 used a special plug, that 
connected to 220VAC.  It does not. 

Jim, if your friend has the rig, and has the plug that goes into the 
back of it (and everything else needed for it) then yeah, you could puot 
it on 75m AM phone.  The single 250TH modulated by a pair of 100TH's was 
a military wonderment, in it's day.

73 = Best Regards,
