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 […]
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 long weekend, over at the Secret Nuclear Bunker I wanted to try some QRO operating on 144 MHz. Conditions on HF have been up and down, as the sun is very active right now. Using the 9e LFA on a 12m pump up mast and a low noise amplifier (LNA) and solid state linear […]
Members of the SNBCG activated the Kelvedon Hatch Secret Nuclear Bunker over the easter weekend. Selim M0XTA activated 144 MHz working people all over the SE UK. George M1GEO used the 3e beam, this allowed activation on 14, 21 and 28 MHz. I operated 7 MHz using the ground-mounted vertical antenna. The elevated radials help […]
One of the joys of working portable is the ability to operate from a low-noise site. Antenna selection can also provide opportunities to try something different to your home setup. On a mild February afternoon, I ventured out to complete the first portable operating of 2023. The weather was mild 14C and the wind was […]
Portable HF has always been fun, recently I have joined the End Fed Half Wave club. I purchased a few EFHW 49:1 or 64:1 matching transformers and wanted to try these out at a recent LEFARS field weekend. Typically an EFHW will operate on multiple bands, so 20m of wire will provide a resonant antenna […]
