Topband: WD1A wire
Anyone know of a good source for WD1A field phone wire these days? Best I've found so far runs abut 60 bux shipped to WA for a 0.5 km spool. Thanks, Larry - W7IUV _ Topband Reflector
Re: Topband: WD1A wire
Larry try eBay that is where I bought my last 2500 feet for 28 bucks but be sure to not get it tangled as that is a mess or long runs.

Re: Topband: WD1A wire
Thanks Carl, even though it wasn't much help. Need some new wire for some BOG experiments, mostly for 630 meters. Ran outa cheap insulated wire. Considering cat5 because it's cheaper than any single conductor wire you can buy. But WD1A is not as appetizing to the varmits and in my old age, I really hate splicing wire in the snow. Anybody even run bare wire on the ground? I tried that when I was in AZ and it didn't work but the soil at that location was very very good. Maybe it would work here over frozen sand and rock?

It was listed strangely but I forget how; I believe I searched for military wire or something similar. I see some speculators peddling it at .10/ft Carl KM1H - Original Message - From: Larry Molitor w7...@yahoo.com To: topband@contesting.com Sent: Wednesday, August 28, 2013 3:32 PM Subject: Topband: WD1A wire Anyone know of a good source for WD1A field phone wire these days?
