Hi Cort, Just something to keep in mind... You can use a regular radio as a signal generator just as you can use another for your receiver/detector function. Duplexer adjustment is more easily done with some RF-Pads (attenuators) placed on each coax port. I use some 3dB pads fairly easy to

Hi Keith, Do you have the equipment to check each location for desense and effective sensitivity? It would be very hard to make a notch cavity from Hard-line with enough Q to allow a decent 100KHz split. Even placing a band-pass cavities will help only so much... A DCI Filter would not be

Keith, Some of the local guys here had a similar problem and setup as you on ten meters. It turned out that the transmitter, even though several miles away, was saturating the extender (noise blanker). Turning off the extender on the receiver solved the desense problem. These were not

I have found that the main problem in using a talkie as the receiver for tuning the notch in a duplexer is the possible leakage of RF between the signal source directly into the talkie. Most talkies are not shielded at all, and any leakage will cause you to tune a combination of the signal
