Back on April 25 (I'll resend the Email to anyone who missed it offline), I suggested using an analog loaded "rubberized" delay line to handle array phasing. After refining the conceptual idea I think that its time to do a breadboard demo of the concept. To do this, I need to locate a piece of test equipment.

The breadboarding idea is to make a multi-tap voltage programmable delay line; 9 taps would be enough for any of the array configurations I suggested, including my favorite "$10.75" 43 element scheme. So I ask a couple of questions, which perhaps Jim can add to the Tuesday nite agenda:

1. Does anyone have ready access to a VHF-capable vector voltmeter? An old HP8405 or the new TAPR/TenTech VNA would be fine, although there are many other network analyzers that would do just fine.
2. Do we have anyone out there who is just itching (or is it etching?) to work on a small "at home" project? I'd welcome a volunteer who would lay out a suitable set of circuit boards for the phasing breadboard (I humbly have to admit that my PCB-making skills are now quite out of date). BTW,  we can offer any volunteer full access to the complete AMSAT-licensed ORCAD software as an added inducement.
   

Just remember that AMSAT is an equal opportunity exploiter. 73, Tom
