[Repeater-Builder] Doug Hall Voter - What Would One Pay.
Hi Guys, I am wondering what one would pay for a single Doug Hall voter module in good working condition? Be happy to get your replies directly. Regards Kevin.
RE: [Repeater-Builder] Doug Hall Voter - What Would One Pay.
Hi Mike, You did not buy my voter. I still have mine here. History - I brought one a couple of years back for a project in your repeater system Plan was to build 3 remote RX sites and feed it back to the main site (4th RX) and expand the coverage. However our MED (Your FCC) decided to charge for every repeater in the country, this included Amateur repeaters. So if I was to put the 3 remote sites and then have to add a TX to them to get back to the main site they would be required to pay. The group already had 7 repeaters and links, and as most will know getting money to fund repeaters is not easy. Power, rents (ours is good), repairs and now fees, the extra could not be justified. So the project went out the door. So I have been sitting on dead equipment (or money), so decided I would let it go and have someone else make use of it. It's a shame as it would of given more coverage on one freq. in the area. L And thinking now, I believe digital will be the way of the future, but I only wish it could be like the trunking systems, it is intelligent enough to do the switching as and when required to stay online when moving around.

[Repeater-Builder] RLC-3 Controller Question - Related to all Repeater Types.
Hi All, I am in a situation that I need some advice on implimenting an access DTMF tone for you repeater. So far. We have installed a CTCSS tone on the RX of our repeater, and have been asked How does one access it if they don't have CTCSS onboard? Should mentioned the repeater is open, the CTCSS is just to stop the intermittent interference we get from either a garage door opener or home digital TV transmitter. Anyway back to my problem. I am running a RLC-3 controller (6 ports) and I would like to add a feature that would allow someone with a DTMF keypad to enter a tone, like a long-0 or 0-0? Idea would be then for the controller to stay active in COS for around 1 min after the tail drops. Don't want them having to enter the access tone too much, K.I.S.S. I do have the repeater setup for pre-access as it is part of a linked system, the main repeater is set for * then the access codes. I do have a little bit of code that might do the task, but I would like to see if there is any other ideas before I proceed too far into it, might even already be done? Look forward to any replies. Kevin, ZL1KFM.
Re: [Repeater-Builder] Re: 2 digis into 1 antenna
You can TX on both bands at the same time through a diplexer. It does not matter as long as you don't go over the rated Max power for the two. I have run 50watts on both bands through a diamond diplexer without any problems (was using two single band radios) This was then fed into a dual-band diamond antenna. Easy way to get up and running.

[Repeater-Builder] Use of GM300 for Telementry at Repeater
Hi Guys, I am in the process of building a telementry logger for our repeater, using a POCSAG encoder into a GM300. I have gotten the connections coming in from the rear 16 pin socket. Radio is a 8 Ch, but will most likely only be programmed with 1 Ch. Still got to program the Telementry freq into the radio. I do not have a scope or analiser to check the audio out, and going to roughly set it up by ear. So far the audio sounds hot, too high. I do not have a service manual so ask where do I look for the adjustments? Better mention that the pins I am using are 3 - PTT, 5-POCSAG input, 7-Ground, and 10-12volts. These are the 4 connections the POCSAG encoder instructions said to hook up. Pins 15 and 16 are tied together for the speaker, not that it is going to be used. Also on the standard connector that came with the GM300 pins 7 and 9 were jumpered together, however I had to pull pin 7 so I could use the ground encoder. Any help would be grateful. Kevin.
[Repeater-Builder] Slightly OT - Motorola GP328 Disasemble Help
Hi All, Sorry for asking this group, but I know there is a heap of knowledgible people on this group. Right I have a GP328 standard H/H (not the plus model, which is smaller) The front case got damaged and I got a replacement front to make the radio usable again. I have been able to remove the guts from the old one but I am having problems getting the external mic part off of it. I took the black coated piece off, destroyed it actually but I can not seem to get the main connector strip off. Without doing too much damage is there any tips on removing it. I see I have to lift it somehow to be able to get it through the slot in the front case. Speaker and mic are free. Now back to repeaters Thanks Kevin, ZL1KFM.

Re: [Repeater-Builder] Re: Anyone got a Amp-meter Circuit to Repeater Controller for Telementry Readback?
Ed and Others Thanks for your ideas and thoughts. The solar cells have a small regulator in line to the batteries, then batteries to repeater system. We do have mains to the site but this is only for requirements when there is heavy usage and the voltage gets down. The controller will switch to the mains.

Kevin, are you using a charge controller between the solar panel, rpt, and batteries? Does your controller provide any kind of monitoring of current or voltage or state of charge? The op-amp circuits can also be extended in range beyond the VCC by using a voltage divider on each side of the input voltage. 1k 1% resistors are my fave for this divider type of app. Keeps the impedance low enough you can get good gain on the op amp with reasonable component values. You might want to consider some sort of outboard microcontroller based data logger. It could tell you how many charge hours you are getting, and peak amps, total amps, and at what time of day your batteries reach full charge and when the charge controller begins to dump excess voltage. This can let you know your batteries are doing through the days / nights. I built an APRS digipeater some years back that ran solar. Low power short burst tx, It would fail in late December due to lack of sunlight, and be fine otherwise throughout the year. Enjoy tinkering! Ed N3SDO

If so, placing a current transformer in the black lead will give you a output current proportional to to the input. Put a resistor across it and use the voltage input to the controller. The downside to this approach is the controller will talk the current and label it volts. Martin

I also use automotive gasket maker under the crimp ring to help seal out the elements.

He's over 80 years old and still goes out on field news assignments.Can anybody in broadcasting top that? He's seen it all - from the early spinning disk experiments to seeing Klaus Landsberg - a ham - invent the studio to transmitter link to the first flying remote (the Telecopter in 1958) to today's HD cameras that fit in your hand.

It is connected to the groups repeater system of 2x 2mtr repeaters and one 70cm repeater. There have been some DX contacts through it as well as local and with pleasing results, both on quality, strength and distance. Equipment is 2x Mitrek Low-Band radios at split sites, TX is running 50 watts and using Wolf Dipoles for antennas. These are controlled by RLC-2a and RLC-3 controllers. It has voice and CW id's and Top-of-the-hour beacon Ident. It has taken far too long to get up and running, but it is now there. Would be interested once things improve (propergation) in what it operates like further away. Regards Kevin, ZL1KFM. Owner/Trustee. Get Skype and call me for free. sparc_nz Description: Binary data
Re: [Repeater-Builder] New 10mtr Repeater Active from Auckland, NZ (ZL Land) - Slightly OT
Hi Eric, In responce to your email. In NZ the regulary body (Govt) states that access to any Amateur Radio installion must be available to all access. What this means to us that we can only use carrier access, no tones like in a CTCSS system. Unlike in the US there are not that many repeater systems close by that would require some form of tone access to prevent interferance. In our case the closest 10mtr repeater on 29.64 is in Australia some 1200Kms away. Hope this helps explain why we can not use a tone. The short answer is Legal. Regards and Thanks Kevin, ZL1KFM.

This approach would be way better than tacking some added wire onto the existing coil or modifying the screws in which I know that is a bad idea. Is there something special about the Mitrek front-end that you believe would prohibit such a conversion?

[Repeater-Builder] Tait T700 Mobile Repeater
Hi All, I came across a web site that had a listing for a Tait T700 Mobile 70cm Repeater. It appears that they are using one T700 and turning it into a full duplex unit. I have a few T700 UHF radios sitting on my shelf and was wondering about using them as a portable/moble repeater. Does anyone have any information on the conversion?

[Repeater-Builder] Diamond X510 Failure
HI All, After 15 years of faithful service our Diamond X510 dual-band RX antenna has failed. We started getting some noise and poor signal input to the 2mtr repeater. We had decided to check the 2x X510 antennas (1x TX and 1x RX). A couple of weeks ago the TX was checked and found to still be in fairly good condition, we did however solder the crimp joints. Today we pulled the top antenna down which runs the 2mtr RX and the 70cm repeater. Once we opened the antenna we found that it had come apart just above the bottom joint, and the very top of the element was split. Now we know why the RX had turned bad. No recovery for this antenna. We want to replace it with something that can be used for the 2mtr and 70cm repeaters. So far other then the antenna dual-band antennas there is nothing to replace it with from a commercial type. But maybe there is something that could be used? There is a thought that maybe due to the lenght of the antenna and the winds we get up on the hill this has added to the damage. We are thinking to replace it with a Diamond X300 dual-band, a third shorter and a little less gain. Any thoughts on a replacement would be helpful, I will pass it onto the other trustees.

[Repeater-Builder] Power Supply from a PC. Slightly OT
Hi All, This request is slightly OT but still for Amateur and possible Repeater use. I read an artical about using a PC power supply as a 12 and 5 volt/ high amp atable power supply for the bench. Looking over the specs it looks good for 12v at 19A and 5v at over 30A. Was interested and due to the size of the PC power supply takes up a lot less room on the bench then my standard Ham power unit. Before I go and use one of these (Have a couple of spares), I would like to know if anyone has already tried this, and if so what problems has it caused? Being a switch-mode is it very nosiey on HF or even the upper bands? Thanks Kevin. Get Skype and call me for free. sparc_nz Description: Binary data
Re: [Repeater-Builder] Getting a Freq Counter to Read Lower
Jim, Thank you for that information. I remembered a DMV I have with a freq reading on it. I had forgot about it because I had a mishap when moving and the LCD spread in the bottom left corner and put t to one side. Still able to read most of the display. Anyway I pulled it out, and it was able to read Hz, and I was able to use it to set the CTCSS freq. It was bang on with the freq, as I compared it against one a setup with the NZ$1000+ gear I used at work, not bad for a NZ$200 DMV. (CHY 22, Chinese brand) Once again the group came to the rescue.

It only goes up to 1 mHz, and has the counter function as one of the capabilities. It also will tell me the value of unknown capacitors and inductors, along with all the normal volt, ohm, current multimeter functions. I think the meter puts a known inductor across the unknown capacitor and counts the freq that it oscillates on to determine the capacitance. Likewise it places a known capacitor across an unknown inductor to count the osc freq and determine the value of the inductor, so the freq counter was necessary for those functions. I have used mine to tune a PL on freq when it was one of the variable type and it worked fine after the adjustment, so I know it is reasonably accurate. 73 - Jim W5ZIT --- On Sat, 7/19/08, Gmail - Kevin, Natalia, Stacey Rochelle [EMAIL PROTECTED] wrote: From: Gmail - Kevin, Natalia, Stacey Rochelle [EMAIL PROTECTED] Subject: [Repeater-Builder] Getting a Freq Counter to Read Lower To: Repeater-Builder@yahoogroups.com Date: Saturday, July 19, 2008, 4:16 AM Hi All, I have a Optoelectronics Handi-Counter Model 2300.

[Repeater-Builder] Need a Switching Curcuit for AC/Battery Power
Hi, I have a need for switching AC and Battery power at our repeater site. Current setup is mains 230v AC and 12v Battery charging via solar cells. Due to the increasing chargers for mains (and still going up) we want to utilise battery power more and use the mains for back-up and when the batteries drop below 11v. The mains is connected to a power supply at 13.8v, this is in parallel with the batteries. I had built a small switching curcuit with 2x relays. One relay has the AC inline so the mains power supply can be turned off by the controller remotely or by the scheduler. The second relay was triggered by the AC line so that if the mains went off it would tell the controller which would then switch the repeater to low power mode, timers etc. The problem with the way I had set it up was that when the mains was switched off, even with a solid 12+v on the battery the relay would click continusally because the controller for some reason would see a low voltage and switch the mains relay back on. When the volts was back up to the 13.8v the mains relay would switch off again, back to battery power. I may be pulling straws here in what is actualy happening. I have tried to remendy the problem, and had it working for awhile, but it then started doing it again. I woud like some suggestions on what way to go?
