Post Automating a manual tuner
Seems an interesting project.....

Whilst looking at various QRZ pages i found G4EQZ page, and seen that he has added stepper motors to a manual tuner using Arduino.

Anyone else done this?

Yes, I have. Before I run the open wire feeders straight into the shack I remotely tuned an S match unit using stepper motors and relays, quite successfully.

Nothing fancy, it was mainly electro-mechanical and using the SWR meter in the shack.

Is it worth the effort paul or just handy buying a commercial unit?

It depends really, if you like building things, yes it is worth the effort, especially balanced matching units. You can buy them commercially at a cost, they are expensive.
