Members of the Secret Nuclear Bunker Contest Group (SNBCG) assembled at Kelvendon Hatch to try 144 MHz (Earth Moon Earth) EME and MS (Meteor Scatter) over the weekend of the ARRL EME event As a group we have tried with some success MS QSO and this helped lay the foundation for this weekend’s EME event.

On one of our summers days, LEFARS my local club organised a field weekend and it was sunny. The idea was to play some radio in the sun, with multiple stations operating from in the hired field. Members were advised to use band pass filters, this helps keep things friendly to multiple operators. The weekend […]
If you are a licensed amateur radio operator then the small meshtastic boards can be used for APRS as a fun project. 433 MHz mesh never took off unfortunately, so if you have these boards around then they can make a great APRS tracker or igate! The good news is you don’t need a NOV […]
Meshtastic has been well documented on other pages, so if you have arrived here you are probably already aware of the mesh network and its usage. This page is going to document my solar powered project and the learning points. 868 MHz is the band of choice now, with virtually no activity on 433 MHz […]
28 MHz has been open most days this solar cycle, and so it’s been my band of choice from the car. The antenna sizes are much more reasonable, so it’s easier to get an antenna mounted on the car that works well. I have a few options, but if static I have a 1/4 wave […]
This weekend I operated portable HF from the car, but I wanted to try out both a multi-band vertical and an EFHW. The advantage is both are quick, easy to deploy, and relatively cheap. EFHW These can be made of purchased and much will depend on the power level required. The length of wire required […]
This weekend the weather was planned to be over 30C, so I thought it would be better to be outside than stuck in the house. If I could find some shade, and keep out of the sun, this would be ideal. Power and keeping cool The weather was so warm, it was essential to stay […]
