I thought my 200mW Madagascar Mighty Mite (MMM) would benefit from some sort of afterburner, so I dusted off a project shelved in 2011: the Texas Topper amplifier. I had built based on a design by Chuck Carpenter and kitted by Rex Harper. I ran into a couple problems back then, including some difficulty getting the bias right on the mosfet at the heart of the amplifier. In another brilliant move, I managed to burn out said mosfet by grounding it while trying to get it and its heat sink to fit into a metal box.
Over the last few years, there have been a spate of postings from homebrewers taking inspiration from the Soldersmoke podcast to whip up various incarnations of the Michigan Mighty Mite, a very simple rock-bound QRPp transmitter. I’m a little late to the party, but here’s my story.
My final SOTA stop on the way back to Washington, DC from Indiana was at Mount Davis, the highest point in Pennsylvania. Arriving towards the end of the day, I did not take advantage of any of the hiking trails from around the mountain, but followed signs directly to the parking area. A path leads around to a metal observation tower and a path continues past the tower to a sort of rock garden with some informational plaques. Not far from the tower’s base, there are some large boulders, where I set up the radio.
Yes, yet another Sugarloaf. I guess sugarloafs were very popular for long time and people saw them wherever they looked. I activated this Sugarloaf on the way back to Washington, DC from Indiana. This and several other SOTA summits are clustered near the Ohiopyle State Park. I have camped and white water rafted there a couple times in the past, but due to time constraints, I didn’t have much time to hang out in the park proper on this trip.
On the way back towards Washington, DC from Indiana, I passed again through Ohio, this time to the south of the outbound route. I had targeted two SOTA peaks near Ashland, Ohio: W8O/NE-001 (Noblet Benchmark) and W8O/NE-003 (the Ashland County High Point). I did get to both sites, but only activated the former one. Both are discussed, below.
West of Pittsburgh in the direction of Chicago, the SOTA summits are few and far between, and what summits there are subtle, more like slowly graded hills than mountains. However, the Summit County HP, while not a eagle’s nest view, was my favorite summit from this trip.
I felt like I knew this town before I got there from looking at aerial photos and even “driving” some of it using Google Street View. The summit area is wide and flat, so there were a lot of options about where to pitch the antenna: the actual county high point, which is marked along the main road? In the trees behind the cemetery near a commercial antenna? In the parking lot of the Sikh Temple? Or in a park.
After Fairview Mountain and Emmaville Mountain North, we continued roughly along Interstate 70 towards Pigeon Hills North. This area is a mixture of private houses and farms, and from various postings, I got the sense that the folks here value their privacy and aren’t all that warm when it comes to visitors.

Continuing with activations on the way out to Indiana from Washington, DC, the next stop was Emmaville Mountain North, SOTA W3/SV019. The peak is on public property that can be accessed by following Bark Road. When I exited Interstate 70, my phone’s GPS initially wanted me to take Bark Road southwards and wrap all the way around. That didn’t make sense, since going the other way was shorter, so I ignored my cell phone GPS and went up the shortest way. Continue reading “SOTA W3/SV-019: Emmaville Mtn North”
I drove out from around the Washington, DC area to see friends in Valpariso, Indiana this summer and plotted an optimal (and optimistic) course to take me by SOTA summits on the way. There are plenty between Washington, DC and Pittsburgh, PA, but a lot fewer west of Pittsburgh. For optimal coverage, I chose slightly different outbound (Interstate 70) and return (Interstate 76) routes and looked principally at summits within 20 and ideally 10 km of my route, favoring those that would afford quick access.
The path to the summit is less complicated than it looks. Drive along Mountain Road until you can’t drive any more, then follow the power lines. Mountain Road starts paved, but transitions to gravel and potholes after a while. I stopped driving when I saw some fairly large boulders in the road, and wasn’t sure of axle clearance. I backed off a bit, pulled the car off to the side, and walked the rest of the way.
