Keith, Are you willing to share the engineering drawings? Kevin

The cavity will not go into the milli Hertz range. If you meant mega Hertz, please use the correct designation. As far as the screw size goes, take another one out and take it to your hardware

Thanks for the 0.1 ohm with 30 A fuse suggestion Andy, as regulation is not critical. I was thinking about using the SS-30s for a repeater power amp. One could be a Micor 75W amp that could be set

Chad, Some of those under $20 miniature surveillance cameras have SD card slots and will capture 2 weeks of video. There is no reason to stream live video to see if the paint is drying. You can also

Hello, I checked the loops on my 4062 cavities to verify the range of the duplexer. The HIGH pass cavities used loop "005", LOW pass used loop "004" Am I correct to assume this duplexer is a "B"

I have a set of those too.? Same issue.? I was able to procure the engineering drawings for the loops and I am looking at making a set for myself. And possibly building a die set to make multiple

Hi, were we going to swap controllers? Or was I going to buy the northcomm from you? I would just buy a new northcomm but the northcomm site doesn't accept PayPal so I can't use my PP Credit

Hi to All, I have a Zetron 48-JR with a receive audio problem and was wondering if a members has the schematic of this contr?ler? On the R-B web site I could only find the brochure and installation

John, I think to give an intelligent answer, we also need to know the application. If this were a repeater, I would recommend that you just have one on the PA and one on everything else. Marlo

If you run AllstarLink with the repeater, there is a module for Echolink that has setup parameters for incorporating it in AllstatLink. AllstarLink also makes repeater linking in the future a bit

I’m glad it was helpful John. I know there is some info out there on how to do it, and I’m not saying it can’t be done… just really not a recommended configuration. I work for

Thank you for the extensive information Marlo, and the other great replies also. It sure was tempting to do, until your reply, as these Astron SS-30 supplies have overvoltage, overcurrent, and

I work for an industrial power supply manufacturer, in the engineering dept.? This is not a recommended configuration unless the power supplies are both designed for it. You risk uneven load sharing

There’s an article on the Astron page at repeater-builder that walks you through it.

Sounds good. I will make up the ones for the cavities I have. Thank you, Jim.

Is the PS isn’t built for it, there is always a challenge in balancing current. Even when using diode devices, one unit always supplies a greater portion of the current. There are a number of

I've never done it, but I have a couple astron supplies that have a third connection that is supposed if hooked in parallel. I don't know what it does. Butch

All of the cables both between the cavity "T"'s and the antenna "T" is the same.

Operating 2 supplies in parallel without isolating diodes works until one power supply output shorts out, then takes both supplies down..Isolating diodes should always be used or other method to
