Coming Soon... Beacons VVV, HHH, and WOO
« on: December 02, 2017, 1752 UTC »
Just ordered three beacon boards from Chris that will hopefully be on the air soon. All will be solar powered, frequencies to be determined once they are built.

A dual beacon - VVV and HHH - will be at the same location near the CT/MA border. One with a vertical dipole, the other with a horizontal dipole. Doing this as a propagation experiment. It might be interesting to see how antenna polarity impacts reception over time.

WOO will be located in Worcester, MA. A friend is interested in building kits and we might as well get him hooked on HF radio while we are at it. :)

I've added these three beacons as pending in the HFU Wiki so we can coordinate callsigns and frequencies if anyone else is putting one on the air.

Once an hf signal is reradiated by the ionosphere the polarity has changed to anything but linear. That being said, the vert might be better for longer paths than the horiz due to angle of radiation.
Conveniently located near Vincennes Indiana.

Definitely true... but it will be interesting to see the difference between the two beacons at any period in time.
