Radio silence

This evening was supposed to be a UKAC night for me but with strong winds and flooding earlier in the day I decided not to head up to Sandwidth with a 50MHz antenna, just in case it got nasty. Even though it looks quite down here in the valley (I’m not just talking about 50Mhz activity either- Only GI4SNA can be heard) the top of the hill will be muddy and potentially windy.

So what to do with the radio time. We’ll I’ve been carrying around a plastic case for some time wondering when I’ll get around to using it as a sturdy case for packing up my FT817 and taking on trips with. The case used to hold a complex vice but the parts are happier in my tool box. So i stripped out the old foam and measured up the insides. It measures just about the wrong size for the easy to use pick and pluck foam so I ordered a 5 mm base layer and 40mm deep top layer from eFoam. The job is fairly simple and needs only a very sharp long bladed knife and a bit of patience.

I laid out the rig, tuner, wall wart, battery, mic and a few odds and ends into the case and carefully marked out the positions using a steel rule and marker pen (making sure the marker pen was on the inside of the are to be cut as I didn’t want any left over pen. I suppose you could just as easily cut it and turn it all over  but that may require extra thinking.

So with holes cut out and the bottom layer done, like so (as they say on Blue Peter) there wasn’t much to do apart from fill it up with the goodies. So with a free(ish) plastic case and a few quid's worth of foam I’ve got a budget Pelicase. Probably just as sturdy for my needs and significantly cheaper.

Just one reminder, the blade needs to be very sharp and a light sawing action seemed to cut the foam nice and smoothly. Just one last thing to do is to raid the spare elastic department (If we have one) and form a kind of retaining strap for the bits in the lid.

Who said UK activity night should be limited to on air activity?

Mini Rotator?

Whilst leaning out of the car window and manually turning my decorators pole (complete with 70cms antenna) and waiting for a break in a UKAC (VHF Contest) QSO I thought that there must be a better way of doing this.

The antenna weights way less that 1Kg and the decorators pole has a perfect coarse thread to it so it shouldn’t be too hard to make up a simple attachment with a stepper motor on it, driven of course by the mighty Arduino and its motor shield

Although I’ve not put one of these together and its a bit of a pipe dream whilst work keeps sending me all over the place I’ve seen more that my fair share of articles that use the motor shield to drive stepper motors (guessing its some kind of H bridge / relay arrangement). So I’m guessing (again) that the bare bones of the system could be pulled together over winter. ready in time for next years UKAC series.

I enjoy the UKAC series but running /P has its unique problems up here in West Cumbria. As I type now the winds are getting stronger and we expect the gale force variety over the weekend. Even when we’re not being blasted with salty Irish Sea venturing out /P means that having a car window open in the winter on the top of a hill is ‘challenging’.

So the challenge is on me now to come up with something now that my work project is attempting to shift from ‘Madness’ to simply ‘Frenetic’ between now and November and possibly simply ‘Stressful’ in December.

Once that’s done…hah ha…I’ll concentrate on the single boom  6m / 2m /70cms antenna I’ve been thinking about that means I don’t have to crawl around in the dark with loads of bits in the car.

Still if someone’s done it already, please put me out of my suspense.
