Dan, I knew a Motorola (or Harris) solution was probably going to be the result of my query. L.M.A.O. I've heard your "sales pitch" before, having sat through similar sales and engineering briefings,

Most of us on this list are advanced to expert level in repeater design, installation, acceptance testing, performance verification, operation and site environmental considerations. Although you

Hi John, I noticed you are centering in on the repeater's input. I doubt that's the strongest frequency (that would be like winning the reverse lottery). Look around elsewhere. and probably, you may

Hi John, I listened to the audio and noticed a few things. Each pulse is fast rise/fast fall, 2 or 3 strengths, random, but in spread clusters. Almost like static discharge. Area of coverage suggests

I would agree with that. Environmental noise is almost always above top quality high performance receiver noise floors, so therefore your definition of desense would be occurring, even on a receive

Gale, A friend of mine had one of these early "repeater controllers" that was intended to take two mobile radios (of that era) and make a portable repeater for emergency use.? As I recall, it's a

I accept your apology and look forward to properly educating by using facts backed up by solid engineering.? We all have opinions, but not many of us have the ability to write in a manner that's

I'm looking for a copy of the documentation that came with a device called Port-A-Peater, built by a company called W-S Engineering located in Pine Hill, NJ.? A quality control tag on the inside of

I started this thread and as a relative noob in this area I have appreciated the discourse as to grades of repeaters and some of the issues that come up more often in some than others. Different

I haven't found a way to edit a post. The 2007 Allied catalog lists the series 251 as a diameter of 0.095. Lead diameter 1/16 to 10A 0.025 and 12 to 15A 0.032 The current series 251 are fatter.than to

On my previous post before that I mentioned both environmental / site noise and transmitter noise. I was corrected by David McGough that desense is only defined as degradation due to your transmitter,

John, A few questions: 1) Do you have an attenuator to put between the antenna of the 2nd video and the receiver? This would allow you to narrow the directivity of the source. 2) Have you explored the

Mr. Woodie, Your initial statement about desense was " EVERY repeater has some level of desense, even with the best hardware and duplexers.? It is unavoidable as any high-powered transmission will

I eagerly await an actual technical conversation. How does a GTR8000 outperform other repeaters? Something more than “better components.” Do you have spectrum analyzer plots you can share showing

Clarification of my inclusion of 275 series NOS ONLY.? Low current only. Currently available 275 series are ONLY 20 to 30A and 32V rated.? Specified at 0.133" Old cut sheets for the 275 listed 2

Whatever it is, you will be surprised. You need to do a little more, especially in the DF area. The good news, compared to a human jammer, is that is is there all the time. Can you hear it on a

Hello all. I'm hoping someone can help me track down a new source of noise we're hearing on the input to our local 2m repeater at 147.990MHz. Here's a couple short videos of what it sounds like while

I wonder if he knows of any good repeater controllers to use? ; ) Mick - W7CAT

As a Kenwood Dealer, we sell quite a few of the NXR series for Amateur use (as well as commercial of course). They work excellently in the Amateur service, are pretty much bullet proof and will
