>it's solar-panel wires were almost DOA due to nibblers - maybe a few month's time left and it would be gone if too far to get to... so it came back to someplace to be fixed and put on a fence... :-)
Hi, i made two qrp beacons, first CW only on 27.145 70mw, second speaking their coordinates and power in fm 27.200 and then send rtty, 500 mw tx with 2w solar panel. Both now placed in the forest on trees, in russia, near St.Petersburg.
Both transmitters with their controllers (arduino with cw/rtty/melody/speaking sketch) glued with epoxy resin directly to solar panel.
Today, after reading some posts here i buy 20 4,5w solar elemets, resin, some 8w 250mhz transistors and bunch of quartz generators and resonators.
Now i thinking about wire for antennas, i think stainless steel wire rope for gardens the best choise.
And why beacons here used 4096 khz freq?
