Hi, If a chance arose for a powerful traditional MF beacon in Poland would it be of interest, or has WSPR done away with the need for traditional beacons? By powerful, it would be meant the full lega
Hi Richard, a 100 m high and 300 m long antenna... sounds like an expensive way to generate just 1 W ERP on MF ;-) I'd just love to have one, but I'd rather use it to expand my VLF capabilities. Rega

Hello Richard, IQ2MI is already transmitting a beacon on 476.180 kHz in QRSS-3. You can see the trace for example at http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_remote_Grabber.html (scroll do
Hi again, Am 30.01.2016 00:05, schrieb Richard S: My concept is to have a "real" beacon that would act as a marker of propagation, but when I look at WSPR I wonder if such an idea is outdated and the
Hello Richard, I think it is an excellent idea. Unlike WSPR, anyone with a receiver can hear it without the need for a PC and software. Plain CW is still the easiest way for beacon work. It is not ou
Hi Richard I'm probably the only one in MF transmitting with an antenna installed in a 80m high building (26 floors) By Benidorm standars this is also a small tower. But I'm lucky to have access to t
Years ago, when i was young, i've done an experiment with a portable MF equipment which completely fits into a backpack, including battery, PA, antenna (TX antenna!) and measuring equipment as well a
Hello Richard, Luis, all, a horizontal dipole at low height (versus wavelength) is in theory an inefficient antenna. See http://www.strobbe.eu/on7yd/136ant/#HorDipole. But: 1. "Low height" is less th
