My two cents. I would be in favour of some beacons, as they would allow more continuous prop studies than can be achieved by clg CQ. I think that 100 W WOULD be useful, as, when used with Spectran, t

Hi Bob, I suggest you buy a cheap child's plastic bucket and invert it over the inductor. Rain will definitely make it deteriorate. Spray the bucket with paint to make it withstand the UV a bit long

Gary, both the signal and the noise would be stronger, so there would be no advantage. In order to gain some directivity and hence S/N advantage, you would need broadside spacing, preferably of a hal

Hi Alan, I'm not going to answer your question directly, but rather give you another idea. Since you intended to run a second Bev, presumably you also intended to run separate coax feeds to each. Tha

Hi John, Having used a sloper from ZL for 4 years, I changed over to a top drive arrangement. The latter gave me a 3 dB improvement over the sloper. You may want to try out top drive. If os, run the

The park will be more than enough, Dan. All you need is for the wave impedance to settle close to 377 ohm, and that happens inside a wavelength. By the way, how are you going to measure the field str
