Zinkkromat-møtrik radiotransceiver (ZnO-trx)

Det kræver radioamatør licens at anvende zinkkromat-møtrik tunneldioder på denne måde :-) Nogen der har prøvet det?:

Citat: "...
Meanwhile I have a small transceiver running on 80m band - backwave is 20dB down, frequency shift between RX and TX is 400 Hz, and the output power differs from 100...500µW depending on the day's form of the point contact. Receive works pretty well, I can copy stations from DL and neighbouring countries pretty good, even with a provisional antenna e.g. heater-system versus mains ground.
