10GHz PA Using a Mini-Circuits PMA5-123 3W MMIC

I first read about the Mini-Circuits PMA5-123 3W GaAs MMIC device on the UK-Microwave forum early this year. Thanks to the efforts of Kent – WA5VJB, Maarten – PA0MHE and Rens -PA3AXA  (and possibly others I’m not aware of) several … Continue reading

G3WDG-002 10GHz Receive Converter

I recently finished building the G3WDG-002 receive converter, a project that I started around 30 years ago! At that time I purchased the G4DDK-004 LO and the G3WDG-002 kits to get started on 10GHz narrow band modes (SSB, CW). The … Continue reading

Fun on 10GHz – Adding a Panadapter to the /P Gear

Since completing my 10GHz /P TVTR I have been using it indoors monitoring beacons via rain scatter (RS). Being able to “see” what’s happening on the band is extremely useful. Not only does it help find the signal and peak … Continue reading

Fun on 10GHz – First 12 Months of EME Operation

Inspired by various articles written by VK7MO, G3WDG, GW4DGU and others I wanted to see what I could achieve using just a 1.2m off-set dish and 10 – 12W RF at the feed point. I had my first 1st 10GHz … Continue reading

Fun on 10GHz – Decoding DL0SHF beacon using QO-100 system

Having been away from home for a while I was keen to “get back on the radio”. EME conditions were looking good, degradation very low, Moon near Perigee and Moon pass times good, i.e. not in the middle of the … Continue reading

10GHz Beacon and SA Down Converter

This project is the result of wanting: A small easy to handle, self contained, frequency accurate 10GHz test source that ccould be used for such things as dish / RX alignment, used as an RF source in conjunction with a … Continue reading
