144 MHz Portable Operating

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 […]

Easter Weekend Activation

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 antennas, EFHW

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 […]

EFHW out portable

I used 21m or wire, supported on a 12m spidebeam pole, with the other 9m sloping horizontal. Power was provided by V2L on the car The purpose was to see how repeatable this […]
