I’ve converted a 1.8m fixed dish to have elevation and azimuth control for use mainly on 10GHz EME (Earth-Moon-Earth, aka Moonbounce) Amateur Radio. The drive motors are SDD3 from https://sub-lunar.com Many thanks to Paul W2HRO for pre- and post- sales support. Inspiration to attempt the project was definitely helped by watching @VE6BGT and using info […]
Minimal ADALM-Pluto 10GHz Transceiver
Taking advantage of the 3rd harmonic output of the ADALM-Pluto, and a Ku-band LNB, a very simple full duplex 10GHz transceiver can be constructed.

LoRa 10GHz Ham Radio
Bench experiment using LoRa transceivers on the 70cm ham band (~433 MHz) as IF radios, up and down converting to/from the 3cm (~10GHz) ham band. Inspired by work being done at Open Research Institute (https://www.openresearch.institute/) It could be really interesting to have some LoRa APRS iGate stations/beacons on at 10GHz to promote experimentation.

10GHz Downconverter with Mini-Circuits blocks
The primary goal is to be able to roughly calibrate some signal sources in the 8.4GHz to 10GHz range with known calibrated equipment at lower frequencies. I have a Tektronix RSA306B Spectrum Analyzer, but a receiver with the appropriate coverage would work. Signal paths (really need a diagram!) Uncalibrated 10.5 GHz Source : 30dB Attenuator […]
