Hi, Eddy I used one of the old Ameco vacuum tube preamp/pre-selectors, that I borrowed from my friend, bill, K4CIA, for my KAZ terminated receiving loops several years ago. It was great! - had plenty of gain and because it was vacuum tube, it wasn't susceptible to damage from transmit RF picked up in the loop. I no longer have the KAZ loop, but I'm going to build another one. Bill had a second newer JFET version o fthe Ameco, that I bought from him. I expect I'll have to take more care with protecting the JFET device. T he old vacuum tube Ameco pream work great onn 160, 80, 40 and 30m, where I used it. F course I didn't need it with the 5-band quad for the higher bands - mostly on loop on 160, where the antenna gain was low, but it was a very quiet antenna, and I heard things on 160 that I couldn't hear before. I ran the Ameco into the receive antenna input on my FT-1000MP. Worked great!

If signals get too loud & distort, all I do is reduce the gain on the thing. Works perfectly for me, even if it isn't "...politically correct" in to-day's Topband scene...! ~73~ de Eddy VE3CUI - VE3XZ _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband
