MY OTHER REPLY WAS AIMED AT THE PERSON RUNNING +-9kC DEVIATION. 73 --- In Repeater-Builder@yahoogroups.com, mch [EMAIL PROTECTED] wrote: The 'correct' maximum depends mostly on your neighbors when it comes to the ham band, but you should never run so much as to interfere with adjacent channels. If you are operating in a 15 kHz bandplan where the next adjacent channel above and below you is 15 kHz away, you should run not more than 4.5 kHz deviation (resulting in a 15 kHz bandwidth). That leaves no room for frequency error, but if you're on frequency, and your neighbors are, too, it will help minimize any problems. If you're in a 20 kHz spacing area, 6 kHz may work OK. You would have a bandwidth of 18 kHz. That would allow for up to 0.5 kHz of frequency error on both your part and that of your neighbors. Running 5 kHz deviation would give you both 1 kHz to play with for frequency error since your bandwidth would be only 16 kHz. If you're running UHF in Ohio, give it up - you only have 12.5 kHz to deal with. That means a technical maximum of 3.25 kHz deviation (12.5 kHz bandwidth). You may as well convert to SNFM (2.5 kHz deviation). That said, some receivers, particularly scanners, are now designed with much more narrow filters in them that will cut off at 17 kHz. That means listening to your system on one of those will sound choppy on voice peaks if you're running at 6 kHz deviation, or an 18 kHz bandwidth. So, sticking with 5 kHz is the best bet. It will retain compatibility with commercial specs (who are limited by law to 5 kHz maximum deviation for NBFM). Joe M. mbloom0947 wrote: Dear John, Thank you for the helpful feedback. I can be a bit pig-headed at times. I really wasn't sure exactly what deviation to set. I did monitor other repeaters and they are as wide as I mentioned. Having said that, I will adjust the deviation back to 5 KHz max if that is best practice. Michael Bloom, W7RAT Yahoo! Groups Links -- No virus found in this incoming message.

Re: [Repeater-Builder] Re: HELP: 2 meter repeater intermod problem from pager tr
What some repeater owners don't take into consideration is the accumulated effect of all audio going out on the transmitter. You may find that testing with a single tone, or maybe voice peaks, will give you a good reading. Voice+PL tone+the repeater voice ID can drive the deviation well beyond 5Khz or 6Khz on some repeaters. It's accumulative. A limiter really needs to be used, but some homebrew repeaters don't have this. 73, Joe, K1ike --- JOHN MACKEY [EMAIL PROTECTED] wrote: That should also be the max for a 20 Khz bandplan, to allow a little room for accidental overshoots. -- Original Message -- Received: Tue, 21 Dec 2004 11:38:25 PM CST From: mch [EMAIL PROTECTED] SNIP factual reasons) that 4.5 kHz should be the maximum in a 15 kHz bandplan.

Re: [Repeater-Builder] Re: HELP: 2 meter repeater intermod problem from pager tr
Very true. I always inject my repeat audio right back into the mic circuit so it will have a limiter stage. Also, that is why I always recommend people set their repeater deviation at 4.5 KHz; to allow a little room for over-shoots. -- Original Message -- Received: Wed, 22 Dec 2004 07:32:01 AM CST From: Joe [EMAIL PROTECTED] What some repeater owners don't take into consideration is the accumulated effect of all audio going out on the transmitter.
