Yes, you are correct.

[Repeater-Builder] Vertex VXR-7000 battery backup
We have recently accuired a Vertex VXR-7000 repeater for 70 cm ham service and planned to hook it up to our site battery backup system (~650 Ah with dedicated charger). However the repeater manual states Never reapply AC power to the repeater with a discharged battery connected, as the DC startup current can damage the repeater and battery. Does anyone know if the repeater trickle charger can be disabled? The minimal manual included with the repeater doesn't tell. regards, ---per Yahoo!

[Repeater-Builder] Re: 440 4 Pole Antenna
You might want to download and compare the db-408 sheet, available in the same section. The text includes the coax harness lenghts for the DB 450-470 MHz segements. Through the years, the commercial antenna versions of this antenna had some changes... the mount changed from a tube to the current 1 bent bar (which appears pretty easy to duplicate). Charles' article shows the dipole welded to the mount tube. The early DB versions used pressed and rivot fits with hose clamp mounts. Might be easier to press/rivot secure the elements if you don't have a welder, but Charles method is much more hardy. I could snap some pictures of the older vs new mounts and have Mike make them available. (If there's any interest in said pictures...) One yet to be sorted issue is the dipole centering. Most of the commercial models have the dipole centered around the mount tube. I have one or two factory DB versions of these dipole antennas with the dipole shifted (ie more of the dipole toward the ground or high side). I'll be asking a few antenna enginners I know (at IWCE in April), why the shift done. cheers, skipp Gerald Pelnar [EMAIL PROTECTED] wrote: I think this is the article you are looking for: http://www.repeater-builder.com/antenna/440fdipl.pdf 73, Gerald Pelnar McPherson, KS [EMAIL PROTECTED] http://members.cox.net/wd0fyf/ - Original Message - From: Richard D.

RE: [Repeater-Builder] Re: Digests and stuff, etc.
We used to call those that bought their repeaters like that Appliance Operators and the equipment Jap-Trac's. No slur intended. My radios in my truck are both Icom just because I don't want to put up with all the cables that it takes to make my full duplex Micor work! Paul -Original Message- From: Al Wolfe [mailto:[EMAIL PROTECTED] Sent: Friday, March 25, 2005 9:54 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: Digests and stuff, etc. Kevin, Keep up the good work. I think your poll is a good idea. I was one of those who unsubscribed a few weeks ago when we had a major outbreak of the Russ-and-Dean show. Couldn't stay away, though, and a couple of weeks later re-subscribed. You run a good sig. I believe that Cooktowers is probably a fine company with which to do business. I recently got a quote from them on an item and it was very fair and competitive. I plan on doing business with them. That said, I don't think Dean is generating a lot of business for them here lately. As far as Russ and his radio station goes, Good luck! You'll need it. Having been an owner in the late 70's and 80's I came to know the meaning of Money Pit. Went back to engineering and haven't regretted it. As far as build goes , yes, a lot of us build repeaters. Of course, any yoyo with enough money can buy a box and put it up but where is the satisfaction? A large part of ham radio to me is seeing a need, collecting the parts, and putting the equipment together to fill that need. Putting a machine together that works better than a commercial off-the-self one for ten per cent of the money is challenging and very satisfying to me. I have always built controllers from scratch, too, thinking that the ready-mades were cheating somehow. But now they are so cheap it's probably not worth the hassle to figure out the logic, dig through the data books, make a board, interface, debug, etc. IMHO, the Micor and Mastr II receivers are the best repeater receivers ever made in terms of value. There may be a better receiver made but not for anywhere near the same money. There are probably enough parts out there to keep them running another 30+ years and far beyond. Hang in there. Yahoo!

[Repeater-Builder] Duplexer's Are tuned, Thanks again for the help
Just wanted to let everyone know that I got the duplexer's tuned this afternoon. I was from the start in the right direction, you gentleman led me straight down the path. Only part I missed was reversing the input and output when aligning up the notch side of the duplexer. Makes sense after I had it explained why it was not working. In the end, no decense on the receiver what so-ever, and all the power is not transferred forward from the transmitter. Just have to remember, the signal goes one way, and the notch goes the other, and then it all comes together. Mathew W9MWQ Yahoo!

Re: [Repeater-Builder] Re: TX-RX Duplexer halp again
Thanks Laryn, I found that they were hooked up ok. I think I was just getting super frustrated when nothing was going right. However the duplexers are tuned. Got them going a little while ago. Was doing everything right, just had the rejection turned around on them, actually did them in revverse of what they should have been. You are right, generally these are a 4 can set, mine is a six can set, not sure why they got the extra set, but they are there, and working excellent now.
