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.
