Re: [Repeater-Builder] Rethinking the Possible poll question
Jim, Right now we have a very good relationship with the building owner and the transmitter in there. Our space rent is very nominal and I want to keep it that way. I thinking of trying to hang a rack on the wall that will give us VHF and UHF in the same cabinet, if possible. Our system is located where a person can not walk around the other equipment in the building. They have not complained and I thought it would be a good idea to try and allow at least that much.

Re: [Repeater-Builder] Rethinking the Possible poll question
Kevin, I think our Micor must have been properly converted because it has been on the air for about 25 years according to the original owner who I talk with 2 weeks ago. Our Micro is on 2 meters and has a 70 cm receiver in the cabinet who's frequency I don't know. Need to find that out!! The main reason for a possible change of equipment is the possibility of some digital work later on. Thanks for the pointers.

Bob, Maybe you said and I forget.. What band is the Micor repeater on? Was it ever properly converted to the ham band? My thinking is that if you or someone did a first class overhaul on the Micor that it *could* run rings around something new. The Micor is one of my most favorite radios for repeater service. When properly done, they operate very well in the ham bands, but unlike a GE Mastr II, they require conversion to do so. If your radio was originally built for the 150.8 to 162 MHz range, and was never properly modified for 2 meters, there can be significant improvements to be had. Even if it's a UHF machine, this can be true. Kevin

Bob WB6ODR Digital is no problem with the Micor - it's a direct FM transmitter and in fact was made in a digital paging version called a PURC. I've seen the PURC exciter schematic and they simply injected the digital modulation into the DPL encoder input theres more to it than that but that's the gist of it. Years ago I put a pager decoder on a Micor receiver and as long as the AFC was disabled I had no problems decoding the digital data off the discriminator. Mike WA6ILQ

I bet it was one of those compace mobile duplexers you can hold in the palm of your hand (IOW, not large, and not heavy). He jsut said it was in-band, and didn't specify the split. Joe M.

Bob WB6ODR Side note for your project there Bob, Just because it was on-air doesn't mean it performed well, or even to spec. If you have things like a UHF receiver in the cabinet that you don't know what it is, now is the time to document, document, document... Later on, you'll certainly want to know things like, Just where is that wire from the controller hooked to, and digital photos, drawings of all wiring, etc... are what you'll need. Attack the thing with a label maker too, and label every cable interconnect and every port they plug into. Take lots of pictures. Go nuts. Digital is cheap. Next, find someone with the right test gear and measure all the basics as it's installed at your site. Receiver sensitivity off and on the antenna system, transmitter power level, duplexer isolation, feedline losses... whatever you can measure, and write it all down somewhere -- start your engineering book for the repeater system, and then require that if changes are made, the docs get updated. You'll be happy you did later. And as friends say, if you haven't measured -- you don't know where you're starting from... Nate WY0X

Re: [Repeater-Builder] Rethinking the Possible poll question
Situations are different for different situations :-) Let me recount one experience. A local club was using a Micor mobile for a VHF repeater. Worked fine until the call sign needed changing. About the same time a new maintenance tech took over and declared the Micor as junk (this after he was unsuccessful in figuring out how to burn a new PROM for the call sign change). Since then the club has spent thousands of dollars on repeaters and controllers with bells and whistles. The members appear happy with their machine but in truth, with the exception of a more modern controller, the audio quality and coverage is no different than it was with the old $30 Micor. 73 de Jack - N7OO - Original Message - From: Bob Linda Smith To: [EMAIL PROTECTED] Sent: Friday, April 13, 2007 7:04 PM Subject: [Repeater-Builder] Rethinking the Possible poll question Dear Chuck and everyone else who gave valuable suggestions, It looks like I, and the club, need to rethink this question.

We do have a Moto tech in town and I will make an appointment to visit him next week for some Micor schooling. Thank you all.

Thank you, Bob Smith WB6ODR Bob, An awful lot of people consider the Micor to be the gold standard for a repeater. With Micor mobiles availabile for next to nothing you should be able to maintain a Micor almost forever. As you say yours is 25 years old. What rice box will be running for 25 years that you can maintain for next to nothing? I'd keep the Micor or replace it with another. Al, K9SI
