I’ve launched a new award scheme designed specificity for radio amateurs who enjoy portable operating. ARPOC (Amateur Radio Portable Operators Club) aims to encourage operators to get out in the fresh air with their radio equipment and enjoy portable operating.

ARPOC has plenty of award certificates that can be applied for and are delivered as a downloadable certificate for members to print at home. Take a look here to see them all.

A sample of one of the award certificates available.

It’s early days but I’ve already issued the first award certificate and I know several others are working towards getting theirs.

Another part of my antenna experimenting equipment. A simple ugly choke for HF made with 30 turns of RG213 coax around a 4″ plastic pipe.

I needed a 1:1 balun to use with my home brew doublet but I needed it to go between the ladder line and the SGC-230 tuner so it needs to have stud terminals on both the input and the output. I took a look around and decided that making one was the best option.

It’s made using 11 turns of figure 8 twin lead on two stacked FT240-43 cores. See the pictures below…
