LiFePo4 Battery Shenanigans and Long-Term Review
I recently had recall work done to my car that required access to the fuel tank. Guess where the fuel tank is accessed? That’s right, it’s accessed by removing the rear seat! If you’re familiar with my car, then you … Continue reading
Why Use a DC-DC Charger in a Mobile Installation?
So, you want to add a “house battery” to your van or an “auxiliary battery” to your touring rig? Adding a lithium iron phosphate (LiFePo4 or LFP) secondary battery is not as simple as simply placing it in parallel with … Continue reading
Victron Energy Orion XS 12|12-50A DC/DC Charger
I charged my LiFePo4 auxiliary battery with an Orion Tr 12|12-30A for nearly three years with good results. My only complaint was that the unit heats quickly and then de-rates its power output. The “30-amp” output was usually closer to … Continue reading
MMBT Tour Mechanic as Bicycle Mobile
I shared that I had built a new bicycle mobile station about three weeks ago. I recently returned from its shakedown tour. A close friend, named Sharon, formed a bicycle touring company called Magical Mystery Bike Tours in 2023. She … Continue reading
A Return to my Roots: KE4WMF Bicycle Mobile!

2024 Solar Eclipse Road Trip, Including SEQP and POTA
I had loosely planned this trip in 2017 when a partial solar eclipse passed over Virginia. I was at work and got a brief glimpse of the ¾-eclipsed sun through an office window with a set of borrowed safety glasses. … Continue reading
Feed Line Pass-Thru
I have a cool widget in my setup that I haven’t detailed beyond a small paragraph on my Rover page. I presented the question, “How do I get so many feed lines out of the car and to the roof?” … Continue reading
Yet Another New Tower: Is It the Last?
My trailer-mounted tower was a success during ARRL’s January VHF contest. Unfortunately, there was one area in which it fell short: AGILITY. Sure, the trailer works fine when my goal is to proceed to a destination, park, and operate. On … Continue reading
Hood Mounted Antennas
The idea of hood-mounted antennas had not appealed to me. With my sedans, I would either use a trunk lip mount or, eventually, a hole mount. Trunk lip mounts are not compatible with my GTI because of the plastic cladding … Continue reading
January VHF Contest: Trailer Tower Retired
Happy New Year! Yes, I know I’m a bit late. I’ve been both busy and distracted. I mentioned my decision to build a tower trailer in November. I can’t believe it’s been so long already! What have I been doing … Continue reading
Attaching Displays and Equipment: More Details!
I recently shared a write-up about how I mounted my displays. A recent discussion prompted me to share even more detail. I’m asked fairly regularly, “How did you put that there?” Every make and model of car or truck has … Continue reading
Tower Trailer – Still a Mobile Station?
You may recall that I experienced a functional failure of my roof rack due to the extra leverage applied by its roof-mounted antenna tower. Read here for more info. Note that nearly any factory-installed roof rack is up to this … Continue reading
MFJ-1924 Screwdriver Antenna Controller
This review is way past due. I’ve had my MFJ-1924 screwdriver antenna controller for about three years. I bought it around the same time as my Scorpion Mobile HF Antenna. Later, I replaced it with an automated controller that measures … Continue reading
Mounting the Displays
I’ve been asked many times over the years how I mounted the various displays in my car. I’ve shared photos of a few setups on my other website and in YouTube videos, but I had not shared details on which … Continue reading
Roof Rack Functional Failure: An Analysis
Even before I had improved my micro tower, shared here, I recognized that something was not quite right about my roof rack. I couldn’t find any damage, but could see one tiny sign that the rear crossbar was not quite … Continue reading
Improving the Micro-Tower
NOTE: As I built this improved tower, I noticed a minor deformation of what turned out to be internal rack damage. As a result, this tower now rides on my utility trailer. Keep reading to learn about the tower improvements, … Continue reading
2023 CQ Worldwide VHF Contest
CQ Magazine’s Worldwide VHF contest takes place each July and seems to get mixed reviews. It takes place only on 6m and 2m, or 50 Mhz and 144 MHz. Those who like to work the higher bands often skip this … Continue reading
June 2023 ARRL VHF Contest
My plan for June’s ARRL VHF contest was ambitious: 10 grids and 700 miles of driving! I started my rove at Red Wing Park in Virginia Beach, grid square FM26. That park is usually a bust for me; and that … Continue reading
VHF Contests – KE4WMF/R
I took an interest in VHF/UHF contesting in 2022. My interest isn’t with sitting at a desk and contacting stations all over the world. Instead, it was natural for me to try contesting as a “Rover.” Rovers are not just … Continue reading
Auto Desk Replacement
I assembled the components for my mobile digital amateur radio station in 2021. I started with a RigBlaster PnP by West Mountain Radio and a budget laptop, traveling with it sitting in the passenger seat when not in use. Later, … Continue reading
