Hey guys, I have a hipro r1 UHF repeater for sale. It's in great shape, wired for an arcom rc210. It has the flat audio mod, cat squelch board, and she's ready to plug and play. Asking 500 for it or any reasonable offer. Sincerest Regards, Jed
Re: [Repeater-Builder] Re: HAM Mototrbo Systems
From what some are saying, all 'colors' are active on all repeaters. It's like having a repeater that passes CTCSS. Anyone can use your repeater and you cannot shut the code (or color) off. Again, this is what I'm hearing from some people. Joe M. Nate Duehr wrote: The color codes are like CTCSS or DCS, someone wants to use your repeater they have to know your frequency, and what color codes are active on the repeater, I assume.

[Repeater-Builder] Re: Commercial-Grade Repeaters for 6m
Hi Eric, Before I pointed a bad finger I wanted to make sure they are the same company. We have a pretty decent number of the black face DX-Radio Systems Repeaters on the VHF band and the receivers are pretty bad. Since I don't have to deal with them a lot (IE not really my problem) I haven't paid much attention to where the black face ones were made other than a casual glance when they go into a receive chatter mode from adjacent frequency operation. But I went over to the Sun Valley DX Radio Systems web site and they look pretty much the same radio, just gray faced and obviously a slightly newer design. So... next time I get over to a vault where one of the VHF versions I talk about is in service... I'll get the company information right off the radio. Then I'll confirm they are the same company and really bad mouth their VHF Receiver in a more proper form. But I do suspect they are one and the same company... not to mention I just saw their displays at the IWCE (Las Vegas) convention. If you want to Email me direct... I'll tell you the problem we're having with most all the black face VHF Versions... And on to the next item... I spoke to Kenwood's #1 big cheese (VP Mark J.) and one of the companies top engineers (Toshi, from Japan) at IWCE about no current low-band repeater (and a few other products I'd like to see made available). They realize the lack of a current Low-Band Repeater product there but also acknowledge the market in low band is very small for the required development dollars required. But they both promised to revisit the low-band product line where practical. I currently make 100 watt Kenwood low band repeaters from 690 RF trays and they work just killer (very good). If any of you are going to be at Dayton and would like to meet some of the mentioned inside Kenwood People, please let me know and I'll happily introduce you (in person). cheers, skipp Eric Lemmon wb6...@... wrote: Skipp, The company we're discussing is in Sun Valley, CA: http://www.dxradiosystems.com/ 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of skipp025 Sent: Tuesday, March 09, 2010 8:59 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: Commercial-Grade Repeaters for 6m Try DX radios their repeater are very flexible.

Re: Uniden ARX-1250 and ARX-2125 (on 223 and 224 MHz) Good luck trying to get any help from Cresend Milcom on the circuit diagram. Both the above listed amplifier models are different chassis layouts from each other. the ARX-1225 is what I describe as a more traditional Milcom Cresend layout, where the ARX-2125 is the in a drawer of up to 5 layout. I have a very limited amount of information related to the control circuit of the 1250 because I bought a manual off Ebay for the 1250 layout... on 900 MHz. The manual has a very modest amount of circuit information but anything is better than none. After you initial post I contacted the N2 station web page guy (he's a ham) who had also converted a number of the 2125 units over to FM-Repeater Operation in the 223/224 MHz range. Although his original web pages are down, he said he still had them in archive and that he had sold off that equipment. You might search him out and ask for copies of his conversion web pages. I can probably Email you the model numbers off the/some Milcom Amplifiers, but Cresend is (probably) not going to be any/much help. Email me direct and I'll look at what I have.

[Repeater-Builder] Re: HAM Mototrbo Systems
Answers to most of the Mototrbo questions can be found in the Mototrbo System Planner. Here is some information on color codes and groups copied from that document: Color codes are defined by the Digital Mobile Radio (DMR) standard and can be used to separate two or more MOTOTRBO digital radio systems which operate on common frequencies. The total number of available color codes per frequency is 16. From a radio user's perspective the color code is similar in nature to a Group ID. However, it should not be used for this purpose. Just as Groups are intended to separate users into groups, the color code is intended to uniquely identify systems or channels which operate on common frequencies. In MOTOTRBO systems, capabilities for Group Calls are configured with the portable and mobile radio CPS. The repeater does not require any specific configuration for groups. Radios can be configured to enable the user to select among multiple groups using the radio channel selector knob or buttons, or using the radio menu contacts list. Which group a radio user hears on a given channel depends on a configurable parameter called the RX Group List.

Someone else had forwarded me a copy of the system planner document just this morning, but I hadn't had any time to read/review it. Quickie question (that'll be answered when I get around to reading it, but I suspect the answer is no)... does the System Planner document cover the new(er) trunking functionality at all? (Not that I can afford two or more repeaters, nor need them, nor even a TRBO radio right now... ha... just curious more than anything.) Comparing all these similar-but-different digital systems keeps the brain sharp... digging through their specs looking for something REALLY innovative, is always fun. Nothing in TRBO is all that innovative, so far in my reading. It's well-implemented, and as one local pointed out... it behaves like I expect a commercial radio system to... he was comparing to D-STAR where you *have* to fidget and mess with callsigns, etc... to really utilize all the features... in TRBO, he switches the rig to Channel 1 to talk locally, and Channel 2 to talk to a pre-defined group of IP-linked repeaters... obviously, this is dirt-simple, and keeps the complexity for the user away, and places the complexity choices on the system operator/administrator. Not as flexible by any means, but sometimes you're just looking for it to just work. I'm SERIOUSLY curious to find out how it behaves with collisions in the IP routed world. And their announcement that they have transmission interrupt functionality is fascinating. There's a couple ways they could implement that, but I assume it's a priority decision made by the repeater... one station talking on a particular TG, another keys up (on second channel) on same TG, repeater sees they're a higher priority user, and stops passing the first user's transmission and switches to the second user's... could get very confusing in practice, if the rigs don't have a good way to signal the stop of one transmission and the beginning of the next, but if they higher-priority traffic gets through -- okay, that's good. Now start mixing the collision problem in the IP-linking and the new priority feature. Ahh, a system's integrator/systems testers dream Excel spreadsheet of possible tests comes out of that... would be fun to document it all. Well, if I were getting PAID to do it, it would, anyway. LOL! That testing would be time-consuming, but fun. I bet a few sure-fire examples of unintended consequences would come out of that testing. Then add trunking. The matrix of required tests to document all the scenarios is almost already out of control, mixing all of those features together. They keep adding stuff, they'll hit the too complex to test point, pretty soon. Thanks for the info. Nate WY0X

[Repeater-Builder] Re: Antenna Phasing Question
here is the way to do it, with yagis. I met one of the individuals involved in this effort on a trip to Quincy and also was able to purchase several of the Yagis that were made using the criteria that came out of this excellent work. http://www.repeater-builder.com/antenna/pdf/wr9aea-antenna-n9sn-hr09-79.pdf You can see that aiming the Yagis straight away from the tower gives a really poor radial fire pattern, compared to tangential placement. As I recall, he said they used the Harris Broadcast antenna testing field during off hours but if they had done it as a project the company would have charged a lot of $$ so much they could have never accomplished the work. Note that the antenna modeling was done at 955 MHz so it should be directly applicable to the present discussion. Personally, I would use several panels with combiners to cover one side or the other of a large tower at 900. To get a textbook perfect pattern requires a top mounted antenna.

Thanks both Bob and Skipp for explaining that one odd-ball configuration that would crush the receivers with random cable lengths that just happen to hit the right sweet spot to do this. I suspect, that if someone saw a 20 dB loss while installing this setup, they'd at least STOP and start asking questions -- maybe they wouldn't get it that they'd hit this perfect storm combination -- maybe they'd think they had some kind of receiver failure when it suddenly was really deaf -- but I also doubt that *most* people would hit the problem. Would you agree with that assessment? (Skipp's comment that if there's a train wreck to be found, he'll be there... I know that feeling.) In this case, the owner wrote the poor sensitivity off to site noise. The club was based a good 30 miles from the repeater, but before it was transferred it worked just fine in the target area. After the system was modified/deafened, an article was written in the club newsletter explaining how the repeater was too far away from the club's user base for HTs to work there. Funny how after the repeater was sold off to yet another trustee, it suddenly began to receive well again. That's when I found out what was done that made it so deaf in the interim. Bob NO6B

Some of the documents posted there may answer your questions. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of MCH Sent: Friday, March 12, 2010 12:47 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: HAM Mototrbo Systems Great info. I assume that users are shut off via a 'kill code' to the radio since the repeater cannot be used to allow selective access. Also, is there a URL for the system planner? Joe M. nj902 wrote: Answers to most of the Mototrbo questions can be found in the Mototrbo System Planner. Here is some information on color codes and groups copied from that document: Color codes are defined by the Digital Mobile Radio (DMR) standard and can be used to separate two or more MOTOTRBO digital radio systems which operate on common frequencies. The total number of available color codes per frequency is 16. From a radio user's perspective the color code is similar in nature to a Group ID. However, it should not be used for this purpose. Just as Groups are intended to separate users into groups, the color code is intended to uniquely identify systems or channels which operate on common frequencies. In MOTOTRBO systems, capabilities for Group Calls are configured with the portable and mobile radio CPS. The repeater does not require any specific configuration for groups. Radios can be configured to enable the user to select among multiple groups using the radio channel selector knob or buttons, or using the radio menu contacts list. Which group a radio user hears on a given channel depends on a configurable parameter called the RX Group List. Yahoo! Groups Links
