This is one of the major annual worldwide contests, and since it is scored by ITU Zones instead of countries/entities, it has a more level playing field than an entity-based contest. Plus, there are additional score multipliers available from stations that represent the headquarters of the various national affiliates of the IARU. This year the contest was simultaneous with the quadrennial World Radio Team Contest held in Germany this time. However, the teams are all limited to 100 watts and basic antenna systems, so that was a non-entity here. The contest is only 24 hours, 12UT Saturday to 12UT Sunday (5am to 5am MST). Continue reading
I haven’t been doing much amateur radio this spring and summer. However, I want to participate in the IARU HF World Championship and CQ Worldwide VHF this month. Continue reading
The ARRL puts on a frequency measuring contest every 6 months, whereby a full-carrier signal is transmitted on a particular frequency for a few minutes on different amateur radio bands. Your goal is to measure the frequency of the signal as accurately as possible, preferably within 1 Hertz. Continue reading
It’s been a while, but I finally have put together another video. It starts a new series on small transmitting loops (“magnetic loops”), the workhorse type of antenna at my station. These antennas are a great option for working on HF when you have very limited space. Part I of the series gives introductory information and how to do the calculations to design a loop that works for your situation. Later videos will show how to build and use this type of antenna.
My limited space for transmitting antennas that I can leave up for any useful length of time makes it hard to put up any sort of “normal” antenna on HF, but it also forces me to be a little creative with antennas, which is not a bad thing. Continue reading
Wow, it seems like just 99 posts ago when I started this blog! When I started three years ago, I was just doing shortwave DXing and on the verge of getting heavily into AM and FM broadcast band DXing. This was all due to discovering software defined radio (SDR). Getting into radio listening has gotten me into ham radio and I’m having a lot of fun with that. Ham radio has the bonus of feeding my antenna-building obsession that begin when I built my first tuned loop for AM BCB. Continue reading
