Two days before Hurricane Helene impacted western North Carolina (Wednesday, September 25, 2024), I stopped by the Blue Ridge Parkway for a quick POTA activation to thoroughly test my MTR-3B self-contained field kit.
This was crucial, as I had plans to conduct multiple SOTA activations during the 2024 W4 SOTA campout in north Georgia the following week. (Unfortunately, due to Hurricane Helene, I had to cancel those plans.)
The importance of a full field trial
This is something I always emphasize during presentations about SOTA, POTA, or traveling with radio: don’t assume your field kit is complete and fully functional—you must test it to know for sure.
A field test confirms two things:
- You have everything you need inside your kit to complete an activation.
- Everything in the kit actually works.
When preparing for something like a SOTA weekend or a family vacation, I usually deploy each of my field kits either at home or a local park. I power up the radio and make at least one contact, essentially mimicking a real activation. If everything works, I know the kit is good to go!
This simple process is an incredibly effective way to ensure your gear is ready for action.
Blue Ridge Parkway (US-3788)
That Wednesday, I squeezed in the activation between errands in town. The Folk Art Center near Highway 70 in East Asheville is the perfect spot—it’s a quick and easy detour.
Or at least it was before Helene. Now, with two bridges damaged—especially one major bridge on Highway 70—the two-minute detour to the Folk Art Center has turned into a 15-25 minute round trip, depending on traffic. (You never realize how essential bridges are until they’re gone!)
I parked near the picnic area, grabbed my gear, and headed for my usual picnic table setup spot.
Unfortunately, it was absolutely crawling with ants—likely a result of spilled juice or food. I moved to the other picnic table in the same area.
Testing the MTR-3B Kit in Real-Time
In the video, you’ll see me use every piece of gear in the field kit, except for the “bare bones” arborist throw line and weight. Since I had my other Weaver throw line kit with me, I used it to save time. I’d recently tested and re-packed the throw line in the MTR-3B kit, so I already knew it was in working order.
Setup was quick and easy. Once I connected the antenna and powered up the radio, I used my N6ARA Tiny SWR Meter to confirm I had a good match—since the MTR-3B LCD lacks an SWR meter. Fortunately, I had a perfect impedance match.
Time to play radio!

I started calling CQ POTA on 20 meters, and within minutes, the contacts started rolling in. Woo-hoo! Continue reading Testing my MTR-3B field kit before a weekend of SOTA (spoiler: that never happened)
