[Repeater-Builder] Remote Base Project
Question is, I a am putting a remote base on my RLC2 controller with the RBI-1 interface. All is working ok. What I need some ideas on is how to keep the transmitter from killing the receiver of the repeater? What can be done to isolate the two radios. The radio is a Kenwood TM-731 and is running only 5 watts. What are some thoughts. Thanks. Mathew Yahoo!

Re: [Repeater-Builder] Remote Base Project
More details needed.What is the repeater? WHat frequencies are you trying to use? If running the same band on a remote,you will need lots of antenna separation. We use 140' of vertical separation. You also will not be able to work frequencies close to your own without filters of some type.Some close frequencies will be impossible to use. It all depends on the frequency separation vs. antenna/filter isolation. - Original Message - From: w9mwq [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Friday, May 21, 2004 9:11 PM Subject: [Repeater-Builder] Remote Base Project Question is, I a am putting a remote base on my RLC2 controller with the RBI-1 interface.

Re: [Repeater-Builder] Remote Base Project
Well the repeater is one that I built from a couple of regency repeaters, which is going to be changed here in the near future. The duplexer is a TX RX setup. Won't be able to get that much seperation, at most about 40 feet is what I will be able to get, maybe 50. I can understand the seperation. Would there be any advantage to putting the radio in an RF box for shielding?

Re: [Repeater-Builder] Remote Base Project
I guess it depends on the amount of filtering you can have for each of the frequencies you want to use, and the cable switching needed to use the cavities for that freq. Imagine a coax switch with a port for every frequency you want to activate, now duplicate that so that you can transmit and recieve, you will need a dummy load for each unused transmit port to keep the impedance correct there on the recieve side you will just need the filter with a deep enough notch to get the remote base freq in and keep the rest out. The 731 has 10 memories if my memory is still holding up, so when you are finished you will have a controller with 10 outputs, 20 sets of cavities, 9 dummy loads, 2 10 port switches, 2 more antennas and feedline runs and then you can begin to tune out whatever else you find once you connect the antennas to the outside world. There is a way to do it but it depends on your desire to aquire the components needed to allow it to co-exist, and the patience to get it all working together. In the commercial market it would probably cost about 35-40k to make this work, but with tower tenants on long enough leases to amortize the capital investment it will even pay for itself if nobody gets cold feet. As for a ham radio project, it may not be practical as every time you want a different freq. you will have to go try tuning the associated cavity set/s and that will grow old after a few cold or hot trips to the tower site. It is not a push button adventure if thats what you were thinking, there is a ever present noise floor to contend with not including the noise you have already on-site.

I have successfully installed in-band remote bases at most of my 2 meter repeater sites, and where you cannot get a bunch of antenna separation, filtering is a necessity. Most of the time, a notch filter placed in the remote base line tuned to the receiver frequency can really help. It does the same thing as your duplexer, notches transmitter side band noise on the repeater receivers frequency. Kevin Yahoo!

One of my lower powered 2 meter repeaters will successfully remote base at the next channel, 15 kc away. I use about 100 feet of vertical separation, hand tuned to find the null, and a nice clean link radio. The link radio is a ICOM 2-AT and I run it at 200 mW most of the time.

[Repeater-Builder] Maxtracs as Repeaters, some Questions
Hi All! As the title suggests, I have a couple of questions about the use of Maxtracs as repeater radios, links, etc. I'm a die hard Micor man with 3 Micor and 1 Mastr II repeaters on the air so forgive me as I movefrom 1970s to1990s technology! Hi Hi!! I hope these don't sound to elementary. 1. I've seen the MRT articles for linking 2 maxtracs together, besides theRICK and these adapters,has anyone rig a full blown controller, say a Scom 7k to these bad boys using the 16 pin plug on the back? 2. Under the software control of these radios (RSS) can the RF power out be dialed down low enough as not to mess the finials and still drive an external PA? Low enough maybe to drive a Micor 60-100 PA. (In the Micor, if you turn the power down to low the finals don't like it... a lot!) 3. Not being as robust as a micor/mastrII, what about heat, cooling, fans? Do these radios have any kind of continuos duty rating? 4. Some have called these radios "barn doors" for being so wide open on the front end. Has this been a problem? Can they be preselected? This was a good thing on the Micors! 5. What other pit falls have I missed? A couple of Club members in our weather spotter group are crossbanding an UHF to VHF maxtracs to get back to the repeater and it sounds good and is surprising simple (KISS) to rig and operate. It almost seems to simple. I know this is basically a GR300 so how do they compare? They have done their homework so now I need to do mine! Thanks all! Keep the flames to a minimum!

RE: [Repeater-Builder] Maxtracs as Repeaters, some Questions
The PA's can be turned down but thre is a limit..I have not bothered looking how low it will go but I am sure the Micor PA probably needs in the area of 350mw or so and I doubt you can do that. I don't have the time now but I am actually curiousas to how low it will go. The 16 pin connector will do just fine, try to get Maxtrac's or 16 Channel GM300's. The 8ch GM's with 16 pin can still be used but the pin configuration is not programmable. Also NOT ALL Maxtracs are 16 pin be careful when doing E-Bay. I have used these radios with the ICS controllers without a problem, a controller is not an issue with radios. As long as you have the outputs or are willing to tap inside of the radio any controller will work with any radio. These heatsinks are not very much of anything. I would go 50% and put some high flow fans on it, they can get "red" hot inno time at all. The RICK is fine but audio is somewhat poor, the radios can do much better with some of the other controllers out there.

Re: [Repeater-Builder] Maxtracs as Repeaters, some Questions
Brian Yes the Maxtracs can be used in the same manner as the GM300/M series in the GR repeaters, Uually Maxtracs don't like the power being turned down to far or they will generate some interesting spurs, I usually don't go anylower than 10 watts, on some radio's I have played with I've gotten lucky and been able to go down to 4 watts without any wierd stuff happening, the PA's aren't ment to be continuous duty even turned down they will heat up so a fan is good. I have interfaced maxtracs to Link Communications RLC4's without any problems I also have a 2 watt maxtrac on an RLC3. receive pl will help but as you noted they have a "barn door" for a front end we are currently using a GR400 at 1 of our sites without any major problems Steve KC7YNS Yahoo!

Why? I've done it for about 15 years. I can't use it within about 60 kHz of the local repeater, but otherwise it's fine. I just used a cavity to notch out the repeater TX.

It almost seems to simple. I know this is basically a GR300 so how do they compare? A GR300 is just two GM300 mobiles in a box with a Rick interface and usually a celwave notch only duplexer with 15 amp supply. They have done their homework so now I need to do mine! Thanks all! Keep the flames to a minimum! Brian, WD9HSY PS ... OH Boy! SMT! Just what I need with Bifocals! Oh yeah, no internal mods or jumpers needed unless you don't have a 16 pin accessory connector ...

Re: [Repeater-Builder] Remote Base Project
Hi Kevin I run a star uhf linked system all on uhf between 430-440 here in South Africa , both the repeaters 439/431 and link 434/433 .I have had success with this but there are many factors influencing the end result .

Only if you put the antenna(s) in a shielded box too. You're asking too much of physics by trying to run a remote base on the same band as your repeater :-) I disagree. One of my lower powered 2 meter repeaters will successfully remote base at the next channel, 15 kc away. I use about 100 feet of vertical separation, hand tuned to find the null, and a nice clean link radio. The link radio is a ICOM 2-AT and I run it at 200 mW most of the time. One thing to remember is you usually don't need much power when linking from a repeater site, so, use as little as necessary. Kevin __ Do you Yahoo!? Yahoo!

His problem is the remote base xmtr is taking out the repeater receiver, not the other way around. The (notch) cavity goes in the remote base line, to reduce the remote base transmitter side band noise out of the repeater receiver. Yahoo!
