Topband: Fw: WD-1 Wire impedance

[Merv Schweigert]

It works well,  I use the transformer set up made by C&S engineering,  
now with DXE I think, and WD1 wire.
I used to use electric fence galvanized steel wire for beverages and two 
wire beverages back in ILL
and it worked well.

>> Hi Herb and all,
>> When I was in the Army, 1958 to 1960,, I was a "Field Communications 
>> Crewman". It meant, I helped string telephone wire.
>> We used what was called WD-1TT. It was two separate conductors. They 
>> were twisted, not molded together. Each conductor was made of 3 steel 
>> wires and 4 copper wires making a 7 strand conductor. It might have 
>> been 4 steel and 3 copper.
>> I have never found listings for WD-1TT on eBay. We spliced it by 
>> stripping about 10 inches from each conductor and tying a square knot 
>> and twisting the loose end on the conductor and covering with 
>> friction tape and then Scotch electrical tape. We could run 3 
>> telephone circuits on 2 wires and ground with isolation transformers.
