[Repeater-Builder] Re: Pacific research ri300 controllers
I like them, but they are expensive. They used to make a RI-310 which replaced the factory control boards inside a Vertex VXR-5000 repeater entirely, the RI-310 controlled the receive and transmitter oscillators and power which meant you could do some really neat things with macros. The RI-300 (and 310) have a smart squelch circuit which in my experience works quite well. I have two of them running now on UHF GE Mastr II stations. I don't connect a COR line at all from the receiver up to the controller. It's very convenient to be able to remotely adjust the repeater's squelch threshold. I buy the RI-300's with the audio delay board as well, I run 62ms delay and never, ever hear any receiver squelch crash come out the transmitter audio. The Pacific Research macro capability is unbelievably flexible, to the point that it's somewhat daunting to understand as a novice user. Also I would not even try to deal with one of these without buying the computer programming interface. The Windows programming software will save you eons of time if you are trying to do anything fancy with macros. We also use pairs of RI-300's with a VHF+UHF radio make cross-band repeaters. PacRes used to make a circuit board that replaced the motherboard inside Vertex FTL-series mobile rigs, in much the same fashion as the RI-310 controls the Vertex repeater. We have several of these for our local RACES group and they make really neat frequency-agile cross band repeaters. Other big advantage, the CTCSS encode/decode is built in. You can also run multiple tones, and you can switch the tones on/off and change the encode and decode tones remotely with programming commands which is also handy at times. All-in-all the RI-300 is extremely capable and very compact, but if you are just looking for a box that ID's and plays courtesy tones it's probably more than you want to spend. Feel free to contact me directly if you have any questions that I could answer. 73 Mark Hagler KK7U --- In Repeater-Builder@yahoogroups.com, Jed Barton [EMAIL PROTECTED] wrote: Hey guys, Anyone ever run the pacific research ri300 controller?

Re: [Repeater-Builder] Astron P/S question
Clip the purple wire going to the crowbar. The crowbar in the Astron is one of the most messed up deals ever. Astron also makes and auto reset kit for the crowbar. Or better yet, go find a Mastr II 35 amp supply and be done with it.

RE: [Repeater-Builder] Pacific research ri300 controllers
Jed, I am using the RI310 controller, which is designed to be a drop-in controller for the Vertex VXR-5000 repeater. It is very flexible and capable. Best of all, you can pose any questions about its use to the designer at the factory, and get sound advice directly from the source. www.pacres.com 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Jed Barton Sent: Wednesday, December 10, 2008 10:36 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Pacific research ri300 controllers Hey guys, Anyone ever run the pacific research ri300 controller?

[Repeater-Builder] MSF-5000 PL encode deviation
Gang, New to MSF-5000's. 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.

[Repeater-Builder] Opinions on telewave duplexers
Hey guys, I am in the process of designing a rather large repeater system. Any thoughts on telewave duplexers? I've heard a lot of great things about them, but the only thing I have to compare it with is txrx. Thoughts? Thanks, Jed
[Repeater-Builder] Tait tb7100 verses tb8100
Hey guys, I have a project where a customer wants to go all tait. Here's the million dollar question, what repeater should we get? What holds up better, the TB7100 or TB8100? Can someone point out the differences? I'm a little new to the tait world. Thanks, Jed
