So sending a few 100W square wave into a big antenna is not really recommended. 73, Rik ON7YD We had a Loran-C transmitter design in 1980 that delivered a square wave into the antenna and depended o
[Due to blocking the sun from the Xyl] I am searching for info on the "Decca 80325" [active lf antenna] Info on performance, is it noisy like the DX-One, or links would be great. I have the cct diagr

I have just finished putting up a 6m square loop to measure the field strength of the signal on 136.00. If your signal is the same one as mine, mine bears 015 +/- 10 degrees from me which logically p
Having sorted out QRP tx am now putting out irregular test tx on 135 850. Auto message gives call; input power to ant; locator. Transmission is very slow CW, 1-sec dots, 3-sec dashes. Not quite QRSS.
