Re: [Repeater-Builder] Re: coordination question for the seasoned owners
Yeah, as the former 2 meter and at one time 6 meter coordinator for NARCC here in norther california, I know what you mean about folks wanting instant satisfaction. Stuff takes time! We are volunteers who have actual lives other than our day jobs and coordinating. Paperwork, research, phone calls, plotting coverage, etc. is time consuming. People should wait a while longer before launching thier bitch and moan tirades against a coordinator or the coordinating body. I deal with the commercial side of things these days. Try getting a part 74 950mhz link (radio studio/transmitter links) coordinated *and* licensed in less than 6 months or so. That being said, it is the coordinating body/coordinators job to try and git 'er done in a *reasonable* amount of time.. For some reasonable means the same as instant, unfortunatley. 7treez, Dave Fortenberry, NA6DF - Original Message - From: mch [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Wednesday, January 24, 2007 10:37 AM Subject: Re: [Repeater-Builder] Re: coordination question for the seasoned owners Now the 'rest of the story'. WPRC does not accept modifications of coordination from anyone but the holder of the coordination. That includes in writing or in person. Would YOU want someone else changing YOUR coordination? The transfer of the coordination in question was just requested by the holder days before the meeting and his letter was only seen by the Secretary as of the start of the meeting (as you said - it was in the incoming mail). It never even made it to the coordinator yet! You can't expect something to be processed before it is received. The item in question was received by the Secretary 1/18/07. Rather than mail it to the coordinator, he held it for physical hand-off at the meeting to save the postage. (which is reasonable and common practice) As you noted, once the transfer was brought to light, there was no problem. Had this transfer been sent in earlier, it would not have been an issue at all. Do you send a check in the mail then complain when it is not cleared your bank a few days later? It's exactly the same thing. There is a process paperwork must go through, and it's not a three minute process or even a three day process. Yes there was confusion because someone was talking as if this paperwork was submitted years ago when it was days. It was quickly cleared up when the fact that it was just received was brought to light (as you said). As for they made him relinquish his coordination, and required him to reapply at the next session., what are you talking about? That is an outright lie. The transfer is being processed and will be complete within a week from the day it was received by the coordinator. (and only taking that long due to the fact that 11 other coordination requests were received the day before his). Joe M. Bathgate, Ed wrote: I attended a local repeater coordination meeting WPRC in Butler Pa this past weekend. I was amazed at the amount of argument and bickering the board members did, and seemed to go out of their way to make life difficult for a fellow from a repeater group who travelled several hours to be there. He was there, in person, with documentation, they insisted he dident have the correct information, and refused to even read it.Then the WPRC secretary finally got them to shut up for a moment and read their own mail. Turns out they did have the paperwork in their incoming mail, that they hadent read. He requested a modification of the callsign, and trusteeship. They were not going to fix it. That's just not the way its done Then they chewed on him because somebody else made an error on the paperwork years ago, and instead of just doing a modification, they made him relinquish his coordination, and required him to reapply at the next session.

Re: [Repeater-Builder] antenna site installation / grounding help ( very long )
Well, I had problems with transients sags/surges at one of my broadcast sites, which gave a lot of grief to some of my equipment there. I installed a Tripplite on-line UPS, which solved the issue for me. An on-line UPS allows the equipment to run on the inverter/battery power at all times, and the shore power just keeps the batteries charged constantly. It would take an input of anywhere between 85vac about 140vac, if I remember right. A real lifesaver! just my 2 bits worth... dave NA6DF - Original Message - From: doug [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: Repeater-Builder@yahoogroups.com Sent: Monday, March 22, 2004 7:28 PM Subject: [Repeater-Builder] antenna site installation / grounding help ( very long ) I have a unique site that I need some help figuring out exactly how to handle a unique site installation. Reading through both volumes of the R56 site standards books. I have yet to find anything that talks about abnormal site installations. Here's the background. One BIG bridge. Four concrete pillars. Roadway is approximately 200 feet above the water. Pillar height above the road is 460 feet - about 660 feet AMSL). Equipment access point is 100 feet below the top of the pillar (about 560 feet above the water). This is where the equipment MUST be installed. No option of placing it at the roadway due to some contractual limitations. Access to the site is pretty severely limited due to the traffic, coast guard, police, etc. This is truly one of the best sites still available at no cost - very high - great vantage of the city - free, and a minimal hardline run (100ft) - did I mention free? Besides the fact that the equipment has to be man-handled up to the access point (been there, done that before - cargo net and a bunch of fat guys can work wonders.) there is a problem with power and grounding. The power in the access room is tapped from the bridge lighting system - it's entirely adequate for our requirements (about 16 amps absolute max) but I am unsure of what the best way to protect the equipment from transients would be. In the past, and in my experience, a simple transtector (or similar MOV/SAD device) was entirely adequate for a site installation (think typical, properly outfitted radio site). However, there is NOTHING on the bridge AC system to my knowledge that provides even a little protection to the power circuits on the bridge. Let me tell you that the equipment being installed is a Motorola Quantar repeater - not your run of the mill micor or MSF. Both of those (and other) legacy gear have massive ferro-resonant power supplies that can withstand a lot more abuse than the switching power supply in the Quantar. Since this Quantar is mine (and not some billion-dollar conglomerate) I would like to provide well above average power filtering for it. I am debating some kind of APC UPS or something for the repeater. I know I'll hear volumes about that - but I definitely want something that will prevent sags in the AC power as well as the ability to clamp anything that gets past the old reliable Transtector. The idea here is to plug an APC/UPS into the transtector.. Hopefully providing a little better protection for the repeater. No, I am NOT hauling 4 deep cycle marine batteries up 460 feet to the access point. Ok, on to question #2.. Grounding. Or lack thereof. The only grounding (besides the AC power system) is the lightning rods at the top of the pillar. Besides the fact that there is no way to ground the Quantar cabinet. The big question here is grounding the hardline. In all the installs I have been a part of in the last few years, the hardline outer shell was grounded at the TOP and BOTTOM of the tower - to the tower. I have no luxury of this at this bridge. Discussing this with a local Moto technician who installed a federal gov't repeater on one of the other pillars at this site revealed that the tower crew grounded the hardline TO THE LIGHTNING RODS at the top of the pillar. Don't think 10 foot rods here. more like rooftop 1-2 foot rods. With the antennas mounted to the railing (yes, it's sturdy gavalized pipe sunk into the concrete). The hardline on the other repeater is also grounded at the bottom of the pillar near the government repeater (don't know where though). I need some opinions here. Should I even ground the hardline at all? My concern is that the antenna (direct grounded) will need a proper ground path to shunt any (!) strikes to ground - no ground = nowhere for the energy to go (except blow apart the antenna). trust me - I am NOT a big proponent of tying the hardline to the lightning rods. Anyway, if anyone out there has been there - done that - I'd love to hear your thoughts and opinions. If you made it this far - thanks for the read - i am also looking for what motorola calls a modular rack or T-rack - basically an open 19 rack that has a pedestal at the bottom.

I thought that this was the same all over the country. Maybe this is different in your area. Nothing is fixed in stone, one broadcast group I work with uses both directions for Duplex and direct RPU operation. Sometimes at the same time... go figure. All I am trying to say is that with the Broadcasters repeaters transmitting near the low end of 450 Mhz, it seems prudent that the amateur repeaters would want some frequency isolation from them especially at a co-located site and would want to use a low input frequency for their repeaters. It just make sense! Maybe for better adjacent or co-site operation. Most of the time, there probably isn't a choice. In Northern CA, we deal with a High Power, Over The Horizon - UHF Military Radar problem in the low portion of the band. Just pick your dragon of choice and grab a sword... I guess your local bandplan will take precident in how you operate with either a low input or high input. The current 440-450 bandplan was setup long before I became interested in UHF Amateur Repeaters. I'm happy to say that our current Dysfunctional Coordination Group had nothing to do with that choice. We probably adopted an option of the original ARRL Plan from decades back. Combiners and antenna management are a must in high RF environments! I agree, wish everyone felt that way... By the way, all we had back many years ago were GE mobiles and repeaters so we just bought the crystals for the Ham frequencies we wanted to operate on. Still have a few Pre-Progress, Progress and Master Progress Repeaters in storage. The first boat going down the freeway near my shop might find them attached to the anchor chain. I have to keep them away from the Motorola G Strips, Sensicon and Research Line Cabinets, else they fight with each other or gang up on the RCA Series 500 repeaters.
