Yes the repeater has CTCSS but I turn it off for testing. When on the CTCSS will false but that's not what I'm talking about when I say that the repeater sometimes keys up after the beginning of the page.
I'm going to take another repeater which has a different 1st IF up and test with just as you suggest. It's a VXR-5000 with a 1st IF of 21.6 Mhz and a 2nd IF of 455. The current repeater (a Micor) has a 11.7 IF and is single conversion. Yes, it happens out of the blue. I'm confident that the repeater TX is not part of the mix. The paging does sound a bit different. I've been think that's due to the wide dev (15 Khz plus) and that different receivers would hear that differently. I talked to the tech and he told me the system has a satellite feed. He also told me the same feed goes to their transmitter on 929.0375 Mhz. Basically, there is one controller for both the 929.0375 and the 157.74 transmitters. They also have two other transmitters on 929.6375 and 931.6625. -- Tim :wq On Aug 21, 2010, at 9:18 AM, Matthew Kaufman wrote: > Tim Sawyer wrote: >> >> >> It seems to pick up most of the page.
