LZ1AQ amp
In case anyone is interested, I bought an LZ1AQ type amp from Everett before Christmas and finally got it up today.? I'm using a 4 foot loop made from 1/2 hardline, fed with about 50 feet of RG6, and 8 feet AGL.? I was fat, dumb, and happy with my homebrew? amp based on the G8CQX design with a pair of 2N5109 transistors and a 3 foot loop of the same material but as a mobius.? The difference is amazing.? Just as a point of reference for myself , I am now receiving solid copy NAVTEX on 518Khz from Labrador and seeing signals from Greenland. ?Those stations where not even a squeak previously. Florida and PR boom in like they are local. I am in coastal NJ.? ? NDB stations are all over the place.? 160 and 80 are a pleasure with an S1 noise floor and very little reduction in signals from my transmitting antennas.? Good stuff! |
No need to place it near the amp. I have mine in the "shack" next to my SDR. Regards, Simon On Tue, Jan 28, 2025, 2:20?PM Superlite via <superlite17=[email protected]> wrote:

My bias tee is in the shack about 50 feet or more of coax run to the amp.? I built mine with a PTT trigger relay to cut the power to the amp during transmit.? I also included a DC filter board in the enclosure..because I had the room, so why not. ?https://www.amazon.com/dp/B09JLNYMGV?ref=ppx_yo2ov_dt_b_fed_asin_title |
