[Milsurplus] SCR-522 Help Needed

[Mark K3MSB]

Folks --

I've acquired an SCR-522 that's been modified for 2M Amateur Radio use.  
It was sitting in someone's basement for probably 40 years.

I'm having trouble finding good reference materials on the web to help 
me determine if the unit is in restorable condition.  I'm finding some 
photos that show the unit was in one large case,  and I'm having trouble 
correlating those and my unit.

I think the Transmitter part is complete.  I'm not that sure about the 
receiver though;  I thought it was crystal controlled, yet mine has a 
VFO -- maybe this was a modification for 2M.  Pictures are at

I'm not interested in using this as a 2M AM unit per se;  rather I'd 
like to restore it back to original condition as much as possible and 
still be able to use it on 2M for demo purposes.

Thanks & 73
