Check out the site of W3IY for good microwave operating info, primarily roving. Here you will not learn that much. Bill passed away in September 2005, and his site is kept alive by W1RT. Thanks!

I may be able to help if your problem is related to HAM microwaves: maybe you want to use something from the lab (well - not much there probably - but this needs an update). Maybe I have something in my parts inventory that can get you on the air (lots of cables, semi-rigid, WR-42, ... ask). It is a shame that things DO NOT GET USED. Share the goodies!
