[Repeater-Builder] Interfacing RLS1000 to Rc210 Controller
Good Morning to the Group. I have a new RLS1000 Hub and a RC210 and have read where Skipp and others have been successful in interfacing the hub with the controller for more ports, but don't see how the connections are made. Does Skipp or anyone else have any notes on hooking the two together? Would much appreciate the information and help. Thanks in advance. JIM KA2AJH
[Repeater-Builder] Tram 1481 Dual Band UHF/VHF Antenna
Hi Guys, We spent most of yesterday working on a UHF Mastr II Exec. Repeater, we are using a TRAM 1481 Dual Band Antenna on. This is the high gain 8.3 dB VHF/11.7 UHF. The system uses UHF Repeater, VHF Simplex, and IRLP. The antenna works very poorly on UHF and much better on VHF. The SWR is about 3-1 on both frequencies. The antenna is not DC Ground and there is no shorted connectors. Lack of help prevented us from taking the antenna down and apart at this time. We ran tests by putting the antenna on a portable and working a fixed base and again the VHF pinned the meter and the UHF was weak, only a couple of S units better than the portable rubber duck. Has anyone had a similar problem. I understand that the antenna is a compromise and not as good as a single band folded dipole for example, but several of us have these and they work great except for this one. I am thinking there are enough Tram 1481 out there and someone may have had the same problem. Also there has been many posts about the LMR400 used in repeater service. It is my understanding that the foil type should NEVER be used between duplexers, from the TX, RX to the Duplexers, but I am not sure about between the duplexer and the antenna. Comments please! My friend has the LM400 on the repeater mentioned above and I know it is NOT the present problem as even on simplex the antenna performance on 440 very poor. Thanks again an advance for your experiences and thoughts. 73 JIM KA2AJH
Re: [Repeater-Builder] Higher Output Exciter
Thanks for the information Kevin, I have some factory made 5 watt, 3dB attenuators. If your custom made 10 watt amp was turned down to five watts and the attenuator was used I could get my 2.5watts for the one PA and my 5-10 watts without the attenuator for the other. Do you see any problem using the attenuator with your PA so I could drive the lower power input PA if I needed? What does Repeater Builder (the business) get for the Custom 10 watt amp? Thanks JIM KA2AJH Kevin Custer [EMAIL PROTECTED] wrote: Jim Cicirello wrote: Hello to Kevin and the group. Still another amplifier question: In my case I have a great Micor Repeater and I have a need to increase the output of the exciter to either 3-5 watts or 5-10 watts to drive some commercial amplifiers that operate in that INPUT range. I am wondering what is the best way to get that kind of drive, from the existing 400-500 Mw Drive I have from the Micor Exciter. Have Repeater Builder (the company) build you a custom 2 to 10 watt IPA. (Intermediate Power Amplifier) Since you said the exciter is putting out 400 mW, I'm assuming you need one for 2M or High-Band, but maybe you mean something else. Here are some pictures of a 10 watt 2 meter unit that is stable and adjustable from 5 to 12 watts. The 'secret' is in the custom wound output transformer. Also note the metering shunt that enables the original metering socket to work. I also build a similar version with only one transistor that is stable from .5 to 3 watts. Mathew Quaife, N9LV is running one of these (the prototype) and maybe he will comment on how it is working for him. Let me know... Kevin Custer Pictures Below: Yahoo!

Re: [Repeater-Builder] mobile repeaters
Give this company a try. http://www.pyramidcomm.com/svr214.html You can interface their mobile repeaters with about any radio. Good Luck JIM Glenn Little WB4UIV [EMAIL PROTECTED] wrote: What band? For VHF, it would be very difficult, even if only on one channel due to duplexer size. For UHF, the duplexer is doable, however, it would have to be retuned when you change frequencies, so, not practical. 73 Glenn WB4UIV At 10:41 AM 11/16/05, you wrote: I am curious,what would it take to build a moble repeater,I am wanting something that I can possibley change channels depending on what freq I want to use,it will be more for my use only cause I am in a rural area and want to be able to have my handheld go to the truck and then out with something like 100 watts or even 50 watts,I think that state patrol use something simalar to this but I dont know how to make one for the freqs I want or the cheapest way to do so,THANK YOU Yahoo!

Re: [Repeater-Builder] Chance of a Lifetime (kinda OT)???
Before I built my tower I looked into a situation similiar to yours. I backed away because of the following concerns. The taxes on the property would have been excessive. Check to see what you would have to pay as the new owner. I know of sites that went for 3K and the property was NOT assessed for the selling price. Does the tower need painting or 24 Hour lighting in lieu of painting. Do you have to paint or put up strobe lights. If you have to light the tower which you may if you are close to an airport or over 200' what will it cost you per month for electric. I have heard the average is $75 per month. I kept my tower at 180' away from the airport and no paint or lights are necessary. Is there a fence? Liability is a concern if a kid was to climb the tower. Then there is insurance. Not trying to discourage you but just pointing some things out that I had to consider. Good Luck. JIM KA2AJH Steve Matda [EMAIL PROTECTED] wrote: Here's my situation. I have been looking for a new repeater site for quite awhile. One of my potential sites was owned and previously used by a BIG utility company for a microwave site about 10 years ago. It has since been abandoned and left to deteriorate. It's at about 3000 ft elevation, with an access road about 1/2 mile long that has for the most part eroded away to a four wheeler trail. There's still a transformer on the pole, but no drop, and a 20x10 concrete block building with two 4 masts sticking up about 15 ft from the roofline. Just for kicks and giggles, about a month ago I shot off an email to the corporate website to see if I could get access. Their land agent called me this morning. They want to sell it to me. At appraisal. 1 acre of mountaintop. Am I nuts for thinking this may be the opportunity of a lifetime--if not from a ham radio perspective, then as a business venture (site leasing, etc.)? Just curious if anyone had experience with this. Steve, KE4MOB Yahoo! Groups Links Yahoo!

[Repeater-Builder] Dayton
Hi Kevin: What spaces will Repeater Builder be at this year at Dayton? Looking forward to stopping by again this year. 73 JIM KA2AJH Kevin Custer [EMAIL PROTECTED] wrote: Eric Lemmon wrote: The most recent instance was with a Cushcraft ARX-270 2m/440 antenna. I tried one of these antennas first as a low profile repeater antenna, then as a remote base antenna. I was so disappointed with it that I took it down and threw it in the trash. Yes it was brand new. That antenna will never bother me or anyone else again. I'm not a big fan of Cushcraft antennas anyway, but whoever designed the ARX-270 didn't have a clue Repeater Builder is currently vending a dual band antenna that works well in duplex service. We'll have several at Dayton, with a special show price. Scott and I have installed several for non critical ham repeater duty and are very pleased with their performance so far. Kevin Yahoo!
