Re: [Repeater-Builder] An advocate for a little audio compression
I use a Behringer MDX2200. I think it has been discontinued for some time. It has all the hot stuff you want. Compressor, limiter, and a noise gate. It doesn't take very long to tune it in. If you don't have it right, you'll know it... Looks like they are going for about $75 on eSlay.

Yeah, I know a decent number of you are in-stone same-in to same-out repeater audio levels types. However, I've changed my opinion. A number of operators don't seem to have voices that drive their radios with adequate audio and I always seem to be reaching for the volume control. So I've started adding a modest amount of audio compression to a few repeaters and the difference is a very pleasant and well received change. Consider 6 to 10dB of audio compression in your repeater system if you're constantly reaching for the volume control while listening to more than one person talk at different levels. I'm experimenting with higher and even dynamic audio compression values but for most situations the above values seem to work well. If you're not sure how to add a bit of audio compression to your specific system... wouldn't be hard to describe it as in most cases the hardware is already in place. Transparent or flat through repeater audio can be made louder without causing the world to come to screeching halt. cheers, skipp Yahoo! Groups Links
Re: [Repeater-Builder] Re: Closed Repeaters
If you do have your tent set up on public property, you would not care who enters it? I value my life, how about you? Or in this case, my license. This stuff about holding a frequency hostage... You are certainly welcome to use any frequency that a repeater uses, just not be repeated through it. If the repeater is deemed limited access, you must ask for permission to use it. If you have a closed repeater or know of someone that does, why is it closed? It is monetary, or a decision to limit access to a group of friends? Most I know of, are a group of friends. John At 09:14 AM 7/26/2009, you wrote: The point has been made that a closed repeater (actually any repeater) is private property and others have no right to utilize it. I would agree to that premise except for the fact that the repeater utilizes PUBLIC spectrum. The analogy would be: I have a large tent that I like to set up on my property. If I take that same tent and permanently set it up in a public park and, I keep others from entering my tent, I am using PUBLIC property for my own, exclusive use. Would that set well with most of you? I have a closed repeater that has PUBLIC spectrum coordinated for it. That has the effect of allocating that PUBLIC asset for my exclusive use.

Re: [Repeater-Builder] Suggestions for Gel Cell Charging - Large Array
These units are very popular with RV boat folks. I have the 60 amp version in my truck camper, I am very happy with it. By what I can determine, it will give a full charge in about 8 hours. I have it feeding a 190 AH battery string. You will have to work the numbers to find out the charge time, I would buy the 80 amp version. It will take a while to bring a string that size back up. Make sure you add a low voltage disconnect to protect the batteries. If they go flat, they will never come back to their original capacity. If you use a charge controller, and a 13.6 supply, the job will get done eventually. Note the charge curves. http://www.progressivedyn.com/prod_details/charge_wizard.html Best Converter seems to have good pricing on them. http://www.bestconverter.com/80-Amp-RV-ConverterCharger_p_173.html If you want really snaz it up, use a battery monitor gauge. http://www.xantrex.com/web/id/274/p/1/pt/5/product.asp You can use the alarm relay to trip your controller, to tell you when the battery capacity has gone below the set threshold.

Previously, our repeater was piggybacked on a commercial user's battery back up which gave us working power for about 3 days (duty cycle on the commercial gear was much higher than our equipment). That company has since gone belly up and removed their equipment and back up power leaving us with nothing but AC to rely upon. I've inherited several dozen Gel Cell batteries previously in use for CATV line equipment power supplies. These are rated at 85-90 amp hour. Our plan in the spring is to put 10 of these up on the site for roughly an 800 amp hour array, with plans to go up from there. The vast majority of the Ham plans I've seen on the web are designed for 7-12 amp hour Gel Cell charging at a rate of less than 1 amp. Is there an a relatively inexpensive method of charging these batteries without completely breaking the bank?

Re: [Repeater-Builder] Help with intermod between repeaters.
I hate to tell you, a definite way to eliminate the problem, is a frequency change so that the output of the two transmitters are no longer not 600 khz apart. It is possible that the mixing is occurring in one of the PA's. If the problem is a mix in the TX, an isolator on the offending TX should solve it. I like the Sinclair isolators. 2A-B Most likely a 3rd order intermod product 146.76 X 2 = 293.52 293.52 - 147.36 = 146.16 Bad place for it to end up on. I have run into this problem several times. Telco : I think you meant to say, the trouble must be on your end, it is leaving here ok... I can't use that excuse, my SXS office does not talk to the outside world yet... Good Luck John At 06:34 PM 2/14/2009, you wrote: Bare with me this is a bit long. Our repeater is on 146.76TX / 146.16RX. In the next town the repeater having the problem is on 147.36TX / 147.96RX. Both repeaters are Motorola Micors. Our repeater is a 100 watt PA running about 60watts with a single band pass cavity between TX and a 4 cavity BPBR duplexer connected to 250 feet of 7/8 hard line and a DB224 antenna. The distance between repeaters is about 18 miles line of sight with no obstructions. The other repeater is running a smaller PA driver with an output of 25 watts. I am not sure of the full power capability of this driver. This PA then drives a ¼ KW tube type final set at about 90 watts. This is connected to a 4 cavity BPBR duplexer, 200 feet of ½ hard line, and a DB224 antenna. The problem is when the our repeater 146.76 is in transmit and someone keys the 147.36 repeater a loop condition is set up locking on the 147.36 on until the 146.76 drops. Also audio feedback is heard on the 146.36 repeater. This is typical receiver transmitter intermod. Here is what I have done so for. I checked the 146.76 repeater and there is no signal on it on 147.96 or any other frequency other than 146.76. I then drove to the 146.36 repeater location and from my car in front of the repeater building duplicated the problem by transmitting on 146.76. As we used to say in the phone business, the trouble is leaving here OK. Next I put a calibrated receiver on the TX port of their BPBR duplexer and measured about -50DB when the 146.76 repeater was on. Also I could not squelch out the .76 signal by holding my hands over the antenna of my handheld radio in the building. There is lots of.76 signal down there so I suspect transmitter mixing of the 146.76 with 147.36 in the .36 PA. But where? I disconnected the ¼ KW PA and hooked the driver up directly to the duplexer and the mixing signal on 147.96 is worse. I then put one band pass 147.36, band reject 147. 76 cavity between the PA driver and the duplexer. To my surprise the mixing signal on 147.96 is even higher! I also tried a single band pass cavity with about the same results. Having run out of cavity's I came back home. I realize their PA driver most likely needs to be checked. If the driver PA is ok they will need 30 to 50 DB of isolation between the 147.36 final and the duplexer which will be at least two cavities. I was able to duplicate this mixing with a couple of 2 meter radios, a lossy T connector and a signal generator. I took two high pass cavities out of a duplexer tuning then to pass 147.36 and reject 146.76. I ended up with around 70DB of rejection and 2DB in the pass. I recorded the amount of signal needed to cause the mixing. I then put the cavities between the signal generator and transmitter. To my surprise the amount of signal to start mixing was about the same. The cavities are the type with a T on one port and a compression capacitor for the reject tuning. Some questions I have for the group are: 1. What is the best type of cavity filter to use in this situation and where should it be placed? 2. Has anyone else seen that, been there, done that, and what was your solution? Any information or ideas will be appreciated. Yahoo! Groups Links
