This one, for the time being is going in the attic above my workshop.
Here's todays project:http://www.youtube.com/watch?v=jVnCmJu49jw
I had a micro-controller from a company called ByVac which has a 4" touch screen - which I thought would be useful.
I now have it controlling both the direction and tuning of the loop by touching the screen.
Seems to work pretty well and is silent RF wise on HF up to 21Mhz, then you can hear the rotator moving - but it's quiet. Maybe the servo needs a choke or something.
At the bottom of the screen there is a compass display with a red dot showing the direction the antenna is pointing. you just touch the display to move the dot to where your finger is - or drag it to move slowly.
The buttons at the top are to fast & slow tune the VC.
There are another two buttons on the left which calibrate the rotator - you point the antenna north, click N then south & click S and it works out the calibration for the dial. This bit doesn't actually work yet - but there's always tomorrow! I didn't bother as it seemed to be spot on with my initial values, by chance.
Longer term the plan is to put it on the mast with a 2m Yagi - but I've not built the Yagi yet.
