Yes, if you have enough isolation between them. if so how far should they be spaced? Varies with the site, the receiver performance and the transmitter power level. if not anyone got a awesome deal on a duplexer? The type of duplexer needed (notch only versus pass-notch) is dependent on the RF level at your site and several other things. Note that you will need a better antenna and feedline if you use a duplexer than if you run two antennas. thanks to all who have helped me so far with getting info on this unit. p.s. am licenced for gmrs and ham.

Re: [Repeater-Builder] 220 MHz E F Johnson 529
Snip I got almost 800 milliwatts out of the transmitter/exciter, I am going to feed that into a Japanese RF module when I get the power control working where it won't burn the module up. Paul, Instead of turning the power set control down to 200mW to drive a typical M57776 power brick, consider using the additional power to drive multiple modules. If you run about 400mW of drive and use a power divider and combiner to run two bricks in parallel, you'll have an amplifier thatworks great and makes about 75W. If you're really adventurous, use 3 splitters and 3 combinersto run 4 modules with your 800 mW of available drive. That should make you about 160W or so. If you have sufficientreceiver sensitivity or multiple receivers to supportthe additional transmitter coverage, it'll make a great system. We built a 50W version for a customer in Tucson. He's at (I think) 9000' AMSL. I think he told me his repeater covers 3 states and 2 countries!!

RE: Radio quality (was RE: [Repeater-Builder] UHF Power)
Ok, I'll bite-what's AIP? I have a G707, and don't remember seeing anything labeled like that. Kenwood's AIP = Advanced Intercept Point. It reduces the sensitivity of the receiver which has the effect of reducing receiver-induced intermod by lowering the TOIP/compression point. Although I thought it might just be an attenuator that is switched in, Bob said that what it's really doing is reducing the gain of the first RF stage (I guess there's an RF amplifier before the first mixer). I didn't get a chance to re-measure my V7A with the AIP turned on yet. Course, intermod isn't what it used to be either.

You'd think it should be getting BETTER with all of the VHF/UHF paging activity having dropped off in many areas, IMTS being dead (or in some cases, the channels re-used for other purposes), etc., but that doesn't seem to be the case.

I've seen too many situations where brackets were made by some group member with a welder and they broke, or the bolts broke, or they rusted and later on broke. I purchase brackets from the antenna manufacturer and use the best stainless bolts I can get. Years ago I saw a photo of a superstationmaster that had gotten away from a installation crew when a bracket broke.

There is a split in half capacitor on the main board with the following markings. Can anyone make any since of this or has a circuit diagram of this model or even a wild guess as to an appropriate rating for an audio amp circuit? Here it is: There was a capacitor split wide open on the circuit board – gold one says ade w7 10/25 ebs J-03 GPF If you can steer me in the right direction, that's cool too! 73, Brian -- MZ YAHOO!

Re: [Repeater-Builder] Stationmaster Brackets Refinishing

Im also looking for suggestions to refinish a stationmaster antenna. Ive tried the instructions ive seen on the internet but minimum orders of refinishing materials are 4 gallons. Anyone have any alternate suggestions ? In an email that I received commenting on the painting article it was pointed out that a paint brush is the least practical way to paint an antenna, and a painters mitt was found to be the most practical. And you will drip more than you planned. Don't forget that you will want to put on at least two coats, maybe three. Higher altitudes (like in Denver) have more UV light, and an additional coat may be appropriate. In short, you will use more coating material that you think. Maybe you could find some other groups that have flaky antennas that want to have a recoating party? Mike Yahoo!
