Hello Group.
Pleased to say that after a lot of hard work Allan Wyatt, G8LSD, and I
finally made a QSO over 49.3km on Saturday night.
Anyway, details as follows
Stations:
G0MRF/P
Location: Fairlight, Sussex. Locator JO00HU
Laser power 10mW 670nm (laser diode)
detector OPT210 photodiode
RX 100mm lens
G8LSD/P
Location Dover, Kent. Locator JO01OC
Laser power 3mW 670nm (laser diode)
detector OPT211 photodiode
RX 120mm reflecting telescope
Distance by GPS 49.3km Date Saturday 5th April 2003.
QSO was modulated CW achieved by switching the laser at 488Hz ( divided down
from a 4MHz crystal)
Does anyone know what the current European record is?
