Hi Folks, Trying to find some info on dup.s I got a t a hamfest this past weekend. I believe they are Sinclair Q-318 dup.s. 4 cans, about 7" round and about 12.5" high. Has the fine and coarse tuning.
Looks like the cables have been mod'ed with rg214 cables and *was* on 443.725/448.725. Looking to possibly cut cables to 449.600/444.600. Might not need to, but need formula to check these. Everything points to the Q series of dup.s Thanks, Robert KD4YDC
