i have an LF (R23/ARC-5, .19 - .55 MHz) receiver that has 3 antenna terminals on it, one marked 'A' and 2 marked "L" (for loop), as in DF Loop. Does any one have an R23 Dynamotor for sale ? ps: if you have one of these receivers in operation, listen for my LF Beacon on 480 KHz sending CW. Paul w0rw
