Shouldn't the 147.765 subscriber station be counted in the mix? While the distance and field strength may vary, the user sending to the 147.165 does make a contribution to the mix. sb

Kevin, Please allow me to pick your brain. I was just informed of an intermod problem with 2 two meter repeaters. They are on towers about 2 miles apart. The frequencies are 147.33+ tone 107.2 & 147.165+ no tone. Two weeks ago I replaced the 147.33 equipment with a Mastr II station repeater & 4 cavity DB duplexer. I believe the 147.165 repeater to be a Micor. When the 165 is on the air, 33 can be heard on the input of 165. I show a third order of 270 kHz away & a fifth order of 270 & 105 kHz away. ------------------------------ Site Name: BG33 Frequency Separation: 600.00 KHz Site Description: Ham Calculate 1st Order: true Company: Calculate 2nd Order: true User Name: Fred Flowers Calculate 3rd Order: true Address: Calculate 4th Order: true Time of Printing: February 03, 2007 Calculate 5th Order: true ------------------------------ *Transmitter Frequencies* 147.16500 MHz 147.33000 MHz *Receiver Frequencies* 147.76500 MHz ------------------------------ *Transmitter Freq(s).* *Receiver Freq.* *Freq.

I have worked on Mastr II's sense they came out. I have spent the same amount of time running from Micor's. J BTW I heard through the grape vine that the owner of 165 added a preamp in the last day or so. I don't know what kind. I don't know how he's dealing with desense. Thanks Fred N4GER
