[QUOTE="Henry Cohen, post: 50094, member: 123"] Re: WinRadio and Workbench Please define what you call "interfering signals" and "intermodal frequencies". If the WinRadio is showing IM products due to mixing (what I guess you're calling "interfering signals"?), that WWB through a UHF-R does not, that's a function of the WinRadio front end not being as selective as the UHF-R's. If by "intermodal frequencies" you mean harmonics, then you're overloading the front end of the receiver. Reduce the input until only the fundamental and product frequencies remain. In either case, any scanner or spectrum analyzer (and I use that term very loosely) that can not accurately show the true frequency within +/-50Hz (and even that's not a terrific spec), should not be used. Transmitter frequency error alone will vary from a couple of hundred to a couple of thousand Hertz. [/QUOTE]
