In January 1982 a group of amateurs, including several from the Lothians Radio Society, installed beacons for 6m, 2m, 70cm and 23cm in the county of Angus, using the callsign GB3ANG. Photos courtesy Chris Tran GM3WOJ.

I found the circuit diagram of the 70cm keyer and the diode matrix programming sheet. I re-designed the GB3EDN TTL keyer in CMOS, which was cutting edge technology in those days. The current consumption went down from nearly 1 Amp to 10mA.

Better shot of the antennas, looking solid enough to last for decades! (Which they did!)
