[W2HX]

Al, here is a very interesting interconnection diagram on the back of your C-7673/pcc-1

Gene and the Group,

I have one of these as well, came along with the duplexer.:

Thanks for the nomenclature, Dennis.  This should eliminate the CX-4656, and power two PRC-77's from a single source, including 117 VAC.  I'll retrieve this stuff from storage.  I should have at least on extra
PRC-77 or equivalent, like a 628K1.

If you really want to play with field phones, I have a small collection, including an SB-22.  I never thought anyone cared.  :-(
