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 →

If you have been paying any attention to the world of ham radio DX, you have heard about the DXpedition to Navassa Island. According to Wikipedia, Navassa Island is a unorganized, unincorporated territory of the United States. Haiti (just 40 miles to the east) also claims ownership of the island but it appears that the US currently has control. The Continue reading →

Got Truck...Got Radio
After acquiring a Ford F-150 truck last year, I’ve been working on getting a ham radio installed in it. At times, I have loaded up my vehicle with multiple radios covering HF through 70 cm but lately I am content with just having a reasonable dualband 2m/70 cm FM rig in the mobile. Actually, I used a Yaesu FT-8900 that 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 →

On the topic of operating events for Summits On The Air (SOTA) activations, Guy N7UN suggested focusing on six major events for 2015. Most of these are VHF-oriented but HF activity can also occur on these days. Jan 24-26: ARRL Jan VHF Contest + NA SOTA Winter Activity Weekend (oops, I guess we already missed that one) Apr 18-19: North Continue reading →

Very cool video documenting WRTC 2014...
From the World Radiosport Team Championship (WRTC) website: The World Radiosport Team Championship (WRTC) is a competition between two-person teams of amateur radio operators testing their skills to make contacts with other Amateur Radio operators around the world over a 24 hour period. All teams use identical antennas from the same geographic region, eliminating all variables except operating ability. WRTC2014 Continue reading →

One continuing discussion in the VHF community is how to promote more activity, especially during the major VHF contests. One central theme that always emerges is how to modify the VHF contest rules to make them better, to make them fairer and to encourage new contesters. (Let me say up front that there is room for improvement in the contest Continue reading →
