Previously, I had written about how the use of SSB made the difference while activating Prospect Mountain (W0C/FR-069) for Summits On The Air (SOTA). This time I was the SOTA chaser, trying to work Brad WA6MM as he activated two peaks near Breckenridge, Colorado. It was the Saturday of ARRL Field Day, so I planned to be out at our Continue reading →

Last weekend was the ARRL June VHF Contest, my favorite ham radio event of the year. For me, this is “vhf activity weekend” when all of the vhf radio enthusiasts come out to play on the bands above 50 MHz. The sporadic-e propagation that is (almost) always present during the contest means that 6 meters will be hopping. I entered Continue reading →

Watch Andy K5PO operate Field Day...
In preparation for ARRL Field Day, I will be doing a presentation at our radio club meeting, explaining how FD works. We have lots of newer hams, so I want to cover the basics well. I looked around on YouTube for some video of typical Field Day contacts so our members could hear what it sounds like. This video shows Continue reading →

Sometimes me struggle wit grammar, usage and speling :-)
A while back, I had someone point out a few errors I made concerning the use of metric units. This caused me to review the SI system to make sure I had it correct. (I am sure I’ll continue to screw up a few things but, hey, life is a journey.) The International System of Units, universally abbreviated SI (from Continue reading →

Very cool video...
When we teach the Technician License Class, we provide a simple explanation of Standing Wave Ratio (SWR) that emphasizes the concept of impedance matching. An SWR of 1:1 is a perfect match; anything higher is less than perfect. SWR is an important amateur radio concept, one that is not that easy to explain so I am always on the lookout Continue reading →

What are you doing for FD?
I’ve written before about the flexibility of Field Day and the need to season to taste to make it your own. I have always thought that one of the great things about Field Day is that it can be tuned to whatever interests you or your club. It can be a serious radio contest (well, almost); it can be an Continue reading →

I went to Google Calendar to look up a date and found a whole bunch of birthdays listed. It appears to be people that I am connected to via Google Plus. I wonder how many of them know their birthday is being made public?

Getting ready for Field Day...
For Field Day this year, the Tri-Lakes Monument Radio Association (WØTLM) is planning a one day event that combines our Tech Day training activities with normal Field Day radio operating. This Tech Field Day will have a strong emphasis on radio education and training, including an opportunity to make contacts on the HF bands under the supervision of an experienced Continue reading →

Here's an update on Part 90 radios and ham radio use...
This is an update to one of my most popular posts. We have quite a few licensed radio amateurs that are members of public safety agencies, including fire departments, law enforcement agencies and search and rescue. Since they are authorized users of those public safety channels, they often ask this question: Can I use my VHF/UHF ham radio on the Continue reading →

Last weekend, I had a fun time working the CQ WPX contest on SSB. I’ve always liked the format of the contest with the callsign prefix as the score multiplier (e.g., K1, K2, W1, W2, VE1, VE2 are all multipliers). Its like every new contact is a multiplier. This contest attracts plenty of DX but unlike some DX contests, everyone Continue reading →

I ended almost 40 years of QSLing using paper and postal on Jan 1, 2K15 and haven't looked back. It just makes no sense to buy postage (or cards) in this New World where putting 10K ham radio contacts in the log during a year is more common than any of us ever imagined in the 20th century.

Yep, more stuff from the interwebz
This is another update on important stuff spewing forth from the interwebz. Belden has a good article about why most of our coaxial transmission lines are 50 Ω impedance. Microwaves and RF posted some interesting photos of coaxial cables. The results are in for the ARRL September VHF Contest. Read about my combination SOTA + VHF Contest operation here. The Continue reading →
