Loop motors

Magnetic loop antennas can be very effective, small, antennas. They work well and are ideal for modes like WSPR, JT65, JT9-1 and PSK31 where frequencies don't have to be moved much. Their main disadvantage is they are narrow-band so require retuning if moving very far in frequency and they are directional.

As ever, Steve G1KQH has been tracking down bargains - in this case motors that could be used to either tune or rotate loops.

Tune up your loop remotely, only needs a coupler and a bit of ingenuity which I know your not short of?

Just needs a simple adjustable Voltage regulator.
