QO-100 Experiments – New Down-converter
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
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

An Arduino Based Four Event Sequencer
When putting together a system using RF switching relays, Low Noise Amplifiers (LNA) and RF power it’s important that things are switched at the right time and in the correct sequence. This ensures that the relays do not actually switch … Continue reading

An Arduino Based Antenna Switch For The IC-7300
Since purchasing the IC-7300 I’ve used it mainly on 4m and 6m with the occasional venture down onto the lower bands. With the Sporadic-E season and good conditions on 10m it highlighted one of the shortcomings of the IC-7300… it … Continue reading

An Arduino Based Vector Network Analyser
My first opportunity to experience first-hand the advantages of owning a network analyser was when Charlie, M0PZT kindly brought his MFJ-259 Analyser over and we took a look at a Magnetic Loop antenna that I’d constructed. It was suddenly so very easy … Continue reading

Constructing another K3NG Rotator Controller
I recently spent a day helping a friend setup his new rotator and single 8 element yagi for EME operation. The weather was kind to us and after a few hours work we had everything aligned as best we could. This … Continue reading

10MHz GPS Disciplined Oscillator and NTP Server
Given that most modern transceivers today are available with a built-in TCXO module I was sceptical about the need to have a 10MHz GPSDO (GPS Disciplined Oscillator) as part of the equipment in my shack. That was until my interest … Continue reading
