G3WDG-002 10GHz Receive Converter

Posted on February 15, 2025 by g4hsk

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 →

10GHz Transverter Project – Part 1: 10224MHz LO

Posted on January 20, 2024 by g4hsk

Having spent many hours optimising my 10GHz EME setup I decided against trying to use the same gear for /P operation. I had great fun and learnt a lot building my QO-100 up and down converters so I decided I … Continue reading →

QO-100 Experiments – New Down-converter

Posted on February 13, 2021 by g4hsk

Probably like most people starting out with QO-100 operation I initially used the Goonhilly QO-100 WebSDR to listen to the satellite down-link. This inspired me to experiment with an LNB, a 65cm offset dish, and a NooElec SDR module with … Continue reading →

QO-100 Experiments – ADF4351 SynthShield

Posted on January 21, 2021 by g4hsk

I’ve recently used a number of ADF4351 modules in various projects. The last two modules have been used to provide a single fixed frequency output. An Arduino Nano running the F1CJN single frequency sketch is used to control the ADF4351. … Continue reading →
