I think that I may have just what you need. It's called "Application Notes for the IFR-1500". I started to scan it, but we are having severe lightning storms in the area and my UPS switched a few times. In the Repeater-Builder area on YahooGroups, look at:
<http://groups.yahoo.com/group/Repeater-Builder/files/IFR1500/> If you want more, I'll scan it later. Others with IFR service monitors, or even other types, may want to look at this. It gives basic setup configurations for testing. 73, Joe, K1ike
