For me, the only cure for this is Summits on the air. I’m aiming for 1883 MASL tomorrow. Completely physically drained tomorrow afternoon and psychologically reset (at least somewhat) by Sunday. Recommended!

This week I'm looking at short/stubby antennas, and comparing them to the stock antenna on the Yaesu FT5D. It's probably not going to surprise anyone that these are not very good antennas, but I will try to answer what I think is the relevant question: How bad can they be?

Join me as I build for this quick and easy build of the Powerpole Inline Volt Meter. If you have access to a 3D printer, wire, some Powerpole connectors and a couple of screws, this build will set you back less then 2 Euro/Dollar! Full bill of material and STL files on Github!

2023-10-26: IS0/IS-303 Punta Berritta - Summits on the Air (Sardinia). Last summit of the expedition, and a proper drive-up this time. Drove to within a few meters of the activation zone and walked the last few meters. 29 in the log in 18 minutes running 20W from the FX-4CR.

2023-10-25: IS0/IS-011 Monte Pipinari - Summits on the Air (Sardinia). Elevation 1398m. Another easy summit as long as you don't mind walking among grazing livestock. 45 minutes up and about the same back down. This was one of the few summits on Sardinia I didn't find a fence post to attach antenna.

2023-10-25: IS0/IS-009 Monte Armario - Summits on the Air (Sardinia). Elevation 1433m. Nice short walk from Arcu Correboi. About 40 minutes up and no more then 25 back down. But quite a bit of livestock grazing! The summits was difficult to reach, so I settled for the activation zone...

2023-10-24: Summits on the Air - IS0/IS-014 Punta Soleadduci (Sardinia). Elevation 1358m. Second summit of the day. This is also a potential drive-up, but there was a closed gate at about 1100m, so I left the car there. A little more then an hour waling up and a little less coming back down.

2023-10-24: IS0/IS-012 Bruncu Olinie (Sardinia). Elevation 1370m. Easy drive-up. There's a gate some 100m below the summit. It wasn't locked, but it was closed, so I decided not to push my luck and walked the rest of the way up. Much livestock in the road on the way up and down...

2023-10-23: IS0/IS-003 Monte Arbu (Sardinia). Elevation 1567m. Very nice walk and spectacular view. Spent about 1 hour 40 minutes walking up, but did not choose the best of tracks. If you go there from Arcu Correboi, choose either the track going over Monte Moddu e Littipori or the one closest to it

2023-10-22: Summits on the Air - IS0/IS-302 Bruncu Spina. Elevation 1829m. This is the second tallest point on Sardinia and conveniently just a small de-tour on the way back from Punta La Màrmora. The walk was about one and a half hours with a stunning 360° view.

2023-10-20: Summits on the Air - IS0/IS-004 Punta 'e s'Abile. Elevation 1554m. Second summit of the day, and a great deal more effort. I parked the car and about 1500, elevation, and the summit is at 1554m, so it sounded easy enough. Only problem was the 200m counter ascent from where I parked...

2023-10-10: Parks on the Air - K-2059 Gantry Plaza State Park. Took my son to New York for a week, and had to shoehorn in at least one activation. We walked from Times Square down to the East 34th Street terminal and took the 8 minute ride across to Hunters Point on Long Island.
