Just Another VHF SOTA Contact

On Sunday, I noticed that Brad WA6MM posted that he planned to activate Dakota Hill (W0C/SR-051) for Summits On The Air (SOTA). Dakota is not a good VHF shot from my house but I was planning to be mobile out east towards Black Forest that morning, so it was worth a try. I texted Brad to let him know I’d be looking for him on 2m fm.

Dakota Hill is 10,929 feet and set back into the mountains, so I wasn’t sure if I could make the RF trip over Palmer Divide to work him. I pulled over at the crest of the hill and made a call. Brad had moved off 146.52 MHz due to some intermod interference and was on 146.55 MHz. Brad was using his trusty handheld radio running 5 watts into a half-wave antenna while I had a 50 watt mobile with a 1/4-wave antenna on the roof of the SUV. We made the contact without too much trouble…his signal was half scale on my meter. I listened to Brad work another station as I drove on, losing elevation and losing Brad’s signal on the other side of the hill. That was apparently THE SPOT to make the contact. Height Above Average Terrain (HAAT) is a key factor for VHF SOTA.

I put WA6MM into the log, scoring 6 SOTA chaser points for the 70 mile QSO. No, this wasn’t a rare DX station, no new record set, nothing that exceptional to report, actually. But it was a fun contact, with Brad hiking to a summit in December and me trying to find a location to work him.

This is why I like VHF on SOTA. Just another example of having fun messing around with radios.
