RE: [Repeater-Builder] Poor Mans Repeater Project anyone?
You are absolutely right, Nate! One can go broke just obtaining / keeping-on-hand the necessary test equipment to build/maintain a repeater system, cheap (i.e. poor man's) or otherwise. Either way, you'll be a poor man by the time you finish building your project... hehehe Until recently, I was fortunate enough to have a friend who is in the business (also a ham) assist me with the test equipment end of things. But now, he might be accepting a supervisory position with his company; if this does happen, he/I will lose his access to the test equipment we regularly needed to maintain my 440 repeater with remote receivers (SpectraTAC system). So it looks like I'll be haunting e-Pay more often looking for inexpensive test equipment, and trying to appease the XYL in the process. ;-p Add to that that I am trying to build a 900 machine, and the costs continue to rise... 73 de Mark - N9WYS -Original Message- From: [EMAIL PROTECTED] On Behalf Of Nate Duehr On 4/11/07, skipp025 [EMAIL PROTECTED] wrote: Re: Poor Mans Repeater Project anyone? I'd be interested in reading along and learning, but I'm not sure how much I could help -- I was mentored by MASTR II guys... They work so well for just about any type of project (Joe's 6m split-site is easy with a 6m and a UHF Mastr II mobile pair to swap parts around in!) that I don't know much else... But I'll watch, learn, and comment if I think I have anything useful to add... Pretty much, I'd consider myself a poor man when it comes to repeaters -- I work on club systems to feed my habit... since club members help foot the overall bill, and we all get to enjoy the results. That's probably one thing many budding repeater-builders don't realize... if you get sucked in, even a club paying for parts won't save you... you'll end up buying test gear, good cables for bench testing, good quality adapters and connectors, etc etc etc... it becomes a lifestyle choice to blow money on stupid repeater related stuff... to put it politically-correctly. Add in a weak-signal VHF+ habit and well, it's easy to be broke all the time, but as long as it's fun... why not? Cheap, well-engineered, and soon... pick any two! (As the saying goes!) Nate WY0X

[Repeater-Builder] Opening Salvo Poor Mans Repeater Project
Opening Salvo Poor Mans Repeater Project I'm glad to see a lot of you are interested in doing an interactive type repeater construction project. Some of you already have potential and/or available equipment in your hot little hands. Many of you have already done this type of project and we would hope to read about your experiences with the various projects you've worked on. We might start out talking about ideas related to the receiver section of the project... but it's probably better to first talk about potential equipment (radio) sources. Let us assume for this thread that pretty much much of the surplus new two-way radio equipment around can be considered for a repeater project. Many of us find equipment on Ebay... but other sources are easily located. Ham Flea Markets go on throughout the Country and there are various amateur radio web pages with buy sell sections. As Cell phones replace a lot of traditional two-way radio systems that are/were not able to adjust to their various market locations... you can often find radio equipment at flea markets and yard sales. There are a number of used two-way radio equipment dealers around the country... that number shrinking down as internet stores replace traditional brick and motar surplus radio dealers. So what do we really need from the receiver? Consider the receivers front-end performance? Discriminator Audio? CTCSS decoder build-it or external? How do we obtain a carrier (receive signal) operated switch? Local speaker audio? Repeater Audio? DC operation (power requirements)? Cost? Possible examples of good and bad receiver choices? ... and of course hardware ownership. s.

[Repeater-Builder] Zetron 38 vs. 38a
Hello and thanks for having me on the group Does anyone know/is there any difference between a Zetron Model 38 and Model 38A, aside from the obvious descriptor change? I can only find a manual on the Zetron website for the 38A and want to know for sure before buying a 38 that it is the same/very similar animal Thanks in advance
[Repeater-Builder] Mastr II mobile in repeater service Noise in receiver
Ok all you helpful folks. I need some ideas. I have a UHF mastr II tuned to the ham band. I am using a NHRC-3/M2 controller. I have a 2 meter remote base on the 2nd port of the controller. I have both audio delay boards installed. I am running a TS-64 ctcss board in full encode/decode. My output is 25watts out of the cavities. I am using a set of TX/RX Varinotch cans. I am running a ARR preamp. The problem I have is this. Sometimes on the receive signal it sounds crunchy. A signal will be full quieting and then it will get crunchy and then slowly clear up. On weaker signals the crunchy sounding audio will just stay that way. I thought maybe this was caused by the AD but it was still there when i removed the delay board. This system was on 444.450/449.450 for abt 7 years with no problems. I moved and had to change the frequencies to 448.450/443.450. I also had a IFAS board fail a few months ago and swapped it out with one I had from another UHF Mastr II. Thoughts? ideas? places to start? Bring it on!! I need to make this thing work rght or take it off the air. Dan
[Repeater-Builder] Re: Poor Mans Repeater Project anyone?
here are my stories, at melbourne hamfest several of us got a $100/case of 5 deal on 440-470 Ericsson KMC-300 mobiles, some of us sold them at profit, some of us held on to them, and i built a repeater out of a few of them.. i have one machine thats made out of 2 kmc's and an nhrc2 controller.. works fairly well, however, the broad front end is getting hammered by horiffic spurrious transmitters on my building (mostly quantars)as well as an 800 trunked system (also moto). im currently working on a mastr2 station to repalce it.. the other was a built this at 5 am the day before a tower trip deal, kmc for a receiver and a 100w delta (at 40 watts) for a transmitter.. keys up great, but the audio lines were left unshielded, and the 100kw broadcast antenna 30 feet away is broadcasting latin music on the repeater.. which will get fixed this weekend, either with ferritites, or an mvp repeater. what is scottys spectrum analyzer? im curious! --- In [EMAIL PROTECTED], skipp025 [EMAIL PROTECTED] wrote: Re: Poor Mans Repeater Project anyone?

I have both of them. The 38 is the older ver of the two. The 38A will do more it the way of PL tones and the lasted I looked they both do CWID. The other thing the 38A board is a redesigned board.

The Zetron 38A book is on the Zetron page at repeater-builder, anybody have the 38 ? Or any other Zetron books that aren't there? Zetron has a bad habit of not having any books for older gear... the Zetron page is available as a library... At 04:59 PM 04/12/07, you wrote: I have both of them. The 38 is the older ver of the two.
