Thanks for the information on TAG, John. You’re not so far from me, 80-100 miles, so I’ll give a listen. I don’t have any computers hooked up to the RX so no ability to read QRSS anything, so it will just be me, headphones, and my ears. But will listen for a carrier on that frequency that “comes and goes mysteriously.“ :-) Thanks also for the details of your loop antenna system with tuning caps fixes, etc. That info may come in handy as I (hopefully) set up my own transmitting loop for my long-delayed beacon planned for 178 kHz. So far it’s definitely a multi-year (embarrassed to admit, a resurrected multi-decade) project currently strewn across the workbench in the basement. But it’s got a nice solid signal on 178.00 kHz and loads well and stably into a 50 ohm dummy, but the 2 IRF-510 “finals” (AB1, push-pull) go into runaway oscillation when trying to load the loop despite my rudimentary “tuning” efforts. On the other hand, I’ve currently got my 50’ loop in test mode strung up around the rafters overhead in the basement, so perhaps the problem is that my entire TX circuitry is literally within the loop itself, so oscillation, maybe no big surprise! As they say, “stay tuned.” Thanks again, John. I’ll let you know if I hear the TAG carrier. Bruce WA1HGJ
