Can a Manual L-match Get the Job Done?
Or can it be made just a little bit better? In part 3 of my manpack series of posts I discussed how and why I replaced a perfectly good LDG Z-11 Pro autotuner with a home-made manual L-match.

Is Your Rig Rugged Enough for Field Deployment?
The term "field deployment" can be interpreted in many different ways. To some it could be as simple and easy as setting up inside a warm, dry, comfy vehicle - although I'll admit it can get darn cold inside a vehicle in winter at northern latitudes. Up, Up and Away Field deployment can also mean … Continue reading Is Your Rig Rugged Enough for Field Deployment?
