Preparing to contest

Getting ready to go contesting again. First blog in a while, oh well. My watch battery died (odd segué, what?) so I went to Wal-Mart (ugh) to get a new CR2016. Of course they only come in 2 packs. Anyway, while there I got a devilish idea on how to pack radios for the trip.

Meandered over to the craft aisles, looking for foam. My wife is an evil crafting genius, but I, not so much. And so I pushed and prodded and squeezed packages of foam and batting and filling trying to figure out what I could use as an ersatz Pelican case with pluck 'n' place. I'm a ham. I'm cheap. :-)

Settled on a 4-pack of Morning Glory Foam Seat Cushions; 16 inches square by 1 inch thick. 100% premium urethane foam. Under $8.


With that in hand I wandered over to the kitchen/household goods aisle where I started looking for containers. Found a couple of candidates that looked large enough to hold my goodies but small enough so the gear wouldn't rattle about in transit. Found that a Rubbermaid Handi-Box size S (14x10.5x4 inch, or 7.2 qt) snap case box is a very good fit for an Icom IC-706MKIIG, microphone, power cable and some coaxial adapters. Used one of those electronic labellers to mark the outside with the contents (an instant inventory) and cut the foam with normal scissors as padding and it looks great!


I cut a single block for the bottom, with strips for the sides. A small pad goes over the top of the mic and a larger one over the radio. The lid closes and slightly compresses the foam. The radio doesn't rattle a bit. I made up 3 cases all told for various gear... the FT-290RII with battery pack, the 30A power supply, Bencher BY-1 paddle, K1EL Winkey 2 keyer, cables, headphones, etc. Very nice and the total cost was about $20!

June ARRL VHF contest

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!
