emergency radio cards

Assuming that phones and Internet will work unfailingly forever is extraordinarily popular. This is despite the fact everyone knows they don’t, can’t and won’t. Worse, they will fail when everyone most wants information on what is going on and wants to share information on their needs and situations. I recognize this better than most. While to me the need for a radio-based communication network seems obvious, it obviously isn’t. Planning and preparing for the uninterested is challenging, but I’m up to the challenge. Here you have the best tool I’ve heard of. I made up this graphic intended to be printed two-sided on cardstock, cut into fourths and shared with people who might store it near or with their radio.

Ham Jam and String Fest

The Bitterroot Amateur Radio Club (BARC) and its members operate several radio repeaters in the Bitterroot. These enable people with walkie-talkies, mobile and home radios to accomplish two-way communication over a wide area from Darby to Missoula and beyond. While the club members have the ability and willingness to expand the repeater network, they are expensive to set up, costing significantly over $1,000 each for reliable off-grid mountain-top units that can do the job. This Ham Jam and String Fest is an attempt to attract donations that might extend the network of repeaters through Conner, up the West Fork and up to Lost Trail Pass. If successful enough, this network could reach Salmon and from there much of Idaho. […]

my radio shack is grounded

Coming out of the radio shack is a piece of 3/4″ copper pipe bent into an S for a radio-frequency (RF) ground. Also coming out is a chunk of #6 multi-strand serving as chassis and 120v ground. The ground wire itself is mostly #6 multi-stranded copper wire running a continuous 160-foot loop. At every turn, there are scraps of 3/4″ or 1/2″ copper pipe pounded two feet or so deep until stopped by rocks. electrical and RF grounds out of shackground loop heads north and east ground at south east cornerwest side of ground […]

Conner radio repeater

view up the west fork from repeaterToday I completed my part of construction for the future Ham radio repeater on the knoll above Conner. The first step was to get permission and signed contracts from the landowner allowing it to happen. That wasn’t hard as the new neighbors are great people who are becoming our friends… and who, active in search & rescue, are very supportive of radio communications. Next I had Jeff Cherry of U. S. Communications check the site and design the repeater … that he is donating, including installation. This, by the way, will dramatically enhance the ability of amateur radio operators in the Conner area of getting information to and from Darby, Hamilton, Missoula and beyond. […]
