I assume from your description of the problem that the interfering signal is only present on your input when your repeater TX is up. You may need to take an RF-bulletproof RX Yagi to the site DF the source of the mix while your repeater is TXing. Bob NO6B Yahoo!

I remember PC's radiating a very strong signal at 462.000 - was really noticable at a local hospital. ssbOn 5/8/06, atms169 [EMAIL PROTECTED] wrote:--- In Repeater-Builder@yahoogroups.com, Bob Dengler [EMAIL PROTECTED] wrote: At 5/4/2006 08:38 AM, you wrote: I hope someone can shed some light on this?
