Today I took part in a shortrange experiment on 10 GHz. Because I have not made a contact in a long time, Steve, KB8VAO came over, calibrated the gear, and he ran mobile on 10 GHz. Yes, mobile, running a 10 slot alford slot antenna on a magnet mount on his car. I was able to work him over a 2 km range. Range was poor because of the trees in the path. The experiment did, however accomplish a couple things. 1. Because his rig is phase locked to a stable, calibrated source, I was able to determine that 10368.1 MHz corresponds to 144.128 MHz on my IF rig.
Second, I was able to determine that my 2 watt amplifier was working properly, as his rig runs 8 watts, and we had similar copy even over the weaker paths.
I was running the offset dish on my end, tripod mounted in my driveway, DB6NT transverter (g2 model), into a DEMI 3 watt amplifier.
I believe Steve was running a DEMI transverter with an 8 watt PA into the slot, trunk mounted.
