Make sure all the shields are in place, it's in a metal cabinet, and *MAKE SURE* you have *good* grounds on the whole thing! Don't rely on the ground on the AC line cord. Find a ground rod, or if you're on a building roof, at least a water pipe, like the sprinker pipe (NOT the head!). Use the same ground as the lighting arrestors, ie, run a large (>8 Ga.) wire from the cabinet rail (not just the cabinet) to the point where the ground attaches to the arrestor. -- Jim Barbour WD8CHL Yahoo!

[Repeater-Builder] shield this foreign broadcast ??
Follow up from the original thread !! I have a Micor Motorola mobile repeater operating on 147.165 MHz and I have foreign broadcast transmitting on a frequency of 11.700 MHz which is getting into the IF section of my receiver which also operates on the same frequency 11.700 MHz so my question that I'm asking is how can I shield this foreign broadcast so it will not be able to get into the IF section of my receiver and stop it from constantly keying my repeater up when propagation is good? Subject: Re: MOTOROLA MICOR receiver VHF boogirls2 I been tested different power supplies steel have the same problem? It's Agivate at times and to find a needle in haystack , And when it does this sometimes, doing day time usually was at time at night after 9 p.m. you cannot use it making the noise??
