Anyone help me.... I have a 1.2 GHz repeater, but no service monitor or signal generator for these frequencies. My service monitor, a Singer-Gertsch only goes up to 499.995 Mhz. I have tried using the third harmonic in the 420-427 range but either the service monitor is well filtered, or the signal is too weak to be picked up by the 1.2 GHz receivers... I have thought about an external tripler circuit... Any ideas on this or other possible solutions other than buying a new signal generator (too costly).
