It was a long contest, but it's time to record the goings on. Spent this contest as the high microwave operator for the W2SZ contest group. High microwaves means 10, 24 and 47GHz. We mount these dishes on a single tower (Rohn 25) along with a 440 liaison antenna. There are 3 full sections of Rohn 25, a top section with a mast clamped inside and a base that's attached to a prop pitch motor that we use to turn the entire tower. The guy wires are attached to a free rotating guy collar...
From the top, on the mast:
440 yagi,
10GHz wideband (2 foot dish)
...on the tower
47GHz FSCW (1 foot dish)
24GHz wideband (2 foot dish)
10GHz narrow band (6 foot dish)
Logged my QSOs with Roverlog 2.4.3
Didn't have too much trouble setting up, although there are lots and lots of cables to be run. A note for the future: 10WB cables are short.
The prop pitch means that I can position the tower to about a degree of accuracy, but it also means it takes a while to turn it. That means careful planning between QSOs.
Had a lot of fun. Black flies were out in force and sleep was at a premium but I'll be back to do it again!
