RE: [Repeater-Builder] MSF-5000 PL encode deviation
Guys, Thanks for the comments. Hopefully I'll get some more time to work with it over the holiday and get it up on site. A friend has another MSF-5000 with the same high 900 Hz PL deviation, he's going to look at a resistor change or pot addition experiment.

It's a fixed percentage of the total deviation. It is very clean however, so even though it might measure rather high, it'll be quite inaudible. You'd have to add a resistor somewhere to lower just the PL level. Make sure you measure and set the deviation with the PL turned on. Your total deviation should be set for 4.5 to 5.0 kHz; it will be less without PL. I haven't seen a spec on the PL/DPL deviation in any MSF manual either. Bob M.

Great piece of hardware. But more used to working with GE Mastr II's. Have an MSF-5000 repeater we're trying to get going on VHF. Have experimented with both the on-board controller stand alone as well as off board CAT. Several ee-pots to adjust in the software setting output audio levels, but none specific to just PL encode level. We got it adjusted for 5 KHz output deviation, but noticed the PL encode deviation is a little high at about 900 Hz. I usually like to see around 600 to 750 Hz. I couldn't find in the manuals anywhere what Moto spec'd PL deviation at for the MSF-5000. Looks like the PL level is a fixed percentage without an independent output level adjust. Probably something we are doing wrong in setting levels, but wanted to get some feedback from the group. Thanks in advance! Ralph W4XE

Ralph W4XE One thing I have seen some people do mistakenly is assume that the +/-5KHz deviation spec is for voice audio. It is TOTAL deviation. You should be staying under, really, 4.7-4.8 for ALL audio, WITH CTCSS running...just checking... That said, I remember hearing on a list that the ratio is fixed. Chances are, if you are getting 900 KHz of PL, your voice deviation is too high too.
Re: [Repeater-Builder] MSF-5000 PL encode deviation
I put up a 5000 about 6 months ago and it works well but you are correct in that the ctcss deviation is not adjustable separately. Mine runs around 900hz also with the total with voice set at 4.9khz. Nobody notices a hum though. wb5oxq - Original Message - From: wd8chl To: Repeater-Builder@yahoogroups.com Sent: Wednesday, December 10, 2008 11:09 PM Subject: Re: [Repeater-Builder] MSF-5000 PL encode deviation Ralph Hogan wrote: Gang, New to MSF-5000's.
