How long would you last?

HarryP:

Does the crusher completely crush normal food grade tin cans to a flat circle, or does it just dent them to make them smaller, if you know what I mean?

Good point about antennas. Ditto, the garden doublet will come down and will be replaces with a fine gauge end fed. We now have a tin roof, so while affording great isolation for the shack, we can no longer have in-loft antennas. My solution was to install a soil vent that's configured so that I can hoist a 30m vertical through it. This works fine for long range HF. Of course the horizontal end fed remains the primary NVIS antenna for continuous coms out to 200 to 300 miles.
