It does take some time for the file to download all 23-pages.  However, they are still blank!  I am going to try direct from the repeater builder site and see what happens. Glen, K9STH Website: http:

Hi Steve, you might try putting a short strap across the vac relay terminals for a test. It sounds as if you might be loosing the plate load in an erratic manner. 73, Gerald K5GW In a message dated 5

Hi Steve, you may well be right about grid inductance not being needed at 2m. It could be more for saving some costs. This was the method used in the original Eimac published design by W6PO back in t
