Bob M. wrote: It probably varies according to the guidelines of the coordinating group in the repeater's coverage area. Certainly if the footprint changes (emitter moves, changes power, antenna, feedline, height, antenna type, etc) you will probably need to resubmit paperwork to that effect. In some areas, repeaters are so closely spaced that they're all locked in at their existing power levels and you may not get coordinated if you want change them. I don't recommend that you just go ahead and do stuff anyway, because that just ends up hurting neighboring repeaters, then the FCC may get involved, and if your parameters differ significantly from what's on file, you may lose. If the trustee changes, that should really be a simple paperwork issue. Better to transfer trusteeship of the repeater than to lose coordination because a person died, moved, or their license expired (if at all possible). Some groups think this calls for a completely new coordination effort; I dont. So the bottom line is it depends which isn't very reassuring, but what else can you do. In most metropolitan areas, there's a waiting list for new or modified repeaters on some bands; use it or lose it. If you've got a good site and good equipment, better to try hanging on to it any way possible. Bob M. == --- w2drh [EMAIL PROTECTED] wrote: I think I must be confused.

[Repeater-Builder] Re: Bad adapter
I was really glad I had a new camera from eBay with me for testing. It was unusual that I had it along but I think I should change that and make it a habit to bring one on service calls in the future. I appreciate all the comments; nobody else could relate to this like you guys do. Hmm, I wonder if the miscreant is in the Group, reading about what we think of him... The site manager was there when we arrived, and pointed it out to us. Unfortunately, the owner only cares about collecting the rent, so it's pretty hard to get kicked out. Other than end over end, I mean. :) Although my original message may seem to imply otherwise, we don't really think the guy who hijacked the antenna is the same person who cut the coax. But it's still a really sleazy thing to do, as well as at least slightly criminal (theft by conversion). We also had an antenna stolen at the same site. It was 12 of house wire and a PL-259 connector screwed into a bulkhed connector going through the top of the cabinet. Clearly no one would need such a thing or find any value in it; it was easy to take so it disappeared. This is indicative of the caliber of person attracted by a certain notorious repeater group here in Southern California. They've been thrown out of every other site around, and they've finally landed in ours. If we don't get some support from the owner, they may end up in there alone. There are certainly other places we could be.

[Repeater-Builder] Re: coordination question for the seasoned owners
Coordinators are a savvy lot (well, some of them are), and they know that sometimes a fellow will repeatedly claim that his gear is on the air when in fact it is not. So, they want to be able to kerchunk the thing for themselves. Even if it's closed, the PL tone should be in their files and they should be able to key it up. If they can't, they're going to doubt your veracity. Now, maybe you just had the box functioned off when they checked it (every time), but how are they going to know that? If that's the case, you need to take the bull by the horns and arrange to demonstrate the repeater's existance at a mutually convenient time. If you can't they're going to believe that you have a paper repeater, and they're going to give the channel to someone else. They clearly have doubts about your operation, and you're going to have to meet them half way to straighten it out.

Three times last year I was sent a email asking if the repeater was on the air and three times I answered yes each time. I had even had a on going discussion about having multiple transmitters on the same pair coordinated. I was never asked to prove the repeater existed or even to prove it in any other way. They are trying to de-coordinate me on this pair using this reason. when it has been coordinated as a CLOSED machine for 2 years. My question to you is have any of you guys have ever heard of having a repeater coordination recinded because of this. I know that the FCC rules say that Closed repeaters are allowed and the coordinators will allow coordinating a repeater as closed. I'm looking for further replies or suggestions as how to handle this. The local director and vice-director are actually the ones behind this.

No, you're right. It's got 5 finals and a driver. I've taken a closer look now. Thanks for the help.

That PA takes about 100 mW to drive it, again not for sure though. I will look for a 7792 book. If I have one there would only be that one and I don't want to get rid of it but may be able to copy it. I also may still have a friend in California that has a couple, will email him and see. That PA sounds like a 7792, it does take 24 volts to run that final. The station had a funny analog exciter and a FSK adapter that sat just under the exciter to make it work on digital paging.

[Repeater-Builder] Re: Rule on tampering with a FCC licensed transmiter
From WWII onward it was a federal crime to tamper with a licensed radio station of any kind. It was a matter of national security. But, about 10 or 15 years ago someone noticed that the rule hadn't been used in decades and it was dropped. The only remaining recourse is under local property laws; vandalism, willful destruction, trespassing, etc. Jeff --- In Repeater-Builder@yahoogroups.com, mch [EMAIL PROTECTED] wrote: They most certainly do license transmitters. It's only in the Ham type services the operators are licensed and can put transmitters anywhere (almost). That's why the commercial licenses have coordinates and frequencies on them. As for the rule, I know it exists, but I don't know exactly where offhand. I think it's going to be in the 'lower CFR parts', not in the rules specific to any one service. On the other hand, all the tower signs I've ever seen don't reference any specific rule - they just talk about the site being under the jurisdiction of the federal government. Nobody I know of quotes a specific law. Joe M. Gary wrote: Not sure what you mean John.
