[Repeater-Builder] NWS SAME Decoder?
I'm looking for a SAME decoder to interface to my repeater controller via TTL outputs. It'll be taking audio from a UHF receiver tuned to a link frequency, so a product with a built-in VHF receiver is not what I'm looking for. The CAT WD-100 would do (and then some), but is there another similar product out there right now? James K7ICU
[Repeater-Builder] Re: IC FR4000
Aside from any possible receiver deficiencies, you might want to consider that the Vertex VXR7000 has a pretty weak PA section. The earliest ones came thru with a discrete transistor PA. They became a problem like so many other PA's in that the collector current was too much for the pad melted the solder surface mount caps off. The next step was to add a rf module. This was ok but they didn't resurface the aluminum PA extrusion to accept the module directly. Instead, they created a new pcb added a copper heat spreader plate as a retrofit to the existing aluminum heat sink. The problem there is the copper heat spreader doesn't have enough contact area to the aluminum heat sink to remove the heat from the heat spreader fast enough. I still use the VXR7000 in new installs but not in areas of high use. I still keep several of the retrofit kits rf modules install them as the old units die. Lastly, the internal duplexer, unless tuned with a return loss bridge, can present a poor swr to the PA module pop it prematurely. I've run across a few that I tuned with a tracking generator attenuators that looked good in all other respects but once the factory cables are attached, the output drops the tuning goes off. You have to kinda' fudge the tuning once the factory cables are attached to get the power isolation back. I also noticed the internal duplexer as sold with the unit (Sinclair) is very temperature sensitive. If I mistakenly hold my palm on the duplexer while tuning, that cavity will be tuned wrong once it cools down to room temp. The heat from the power supply the PA will warm the chassis the duplexer throw the tuning off. If you can, use an external duplexer. It won't detune itself due to the heat buildup offers better isolation/less loss. --- In Repeater-Builder@yahoogroups.com, Nate Duehr [EMAIL PROTECTED] wrote: On Jun 2, 2007, at 12:35 PM, barrypal wrote: Anyone running the Icom repeater in the ham bands?

I was under the impression that as long as the transmission was one of direct benefit to the ham community at large, it was not considered broadcasting in the usual sense. Hence, you have W1AW the other news caster org. I don't know that short duration control tones are illegal provided they don't interfere or last for more than a certain time frame the intention of sending the control tones was for the direct benefit of the Ham non-ham community. I could be wrong, I've never been much on rules regs being the bit of a scofflaw that I am.

RE: [Repeater-Builder] Coax length between the TX and diplexer
Not always true. Even if a duplexer presents a flat 50 ohms at the operating frequency to a transmitter, the transmitter may not work properly and you may have to experiment with different lengths of cable between the transmitter and duplexer. The reason is that off frequency the duplexer can be highly reactive and that off frequency reactive load is seen by the transmitter as well as the flat 50 ohms on frequency and some transmitters don't like any reactive load on the finals. They will not load properly and you will not get full power out. Sometimes spurs will be generated by the off frequency reactive load. Now if there is an isolator on the transmitter then the transmitter always sees a flat 50 ohms regardless of what the duplexer is presenting and in that case the length of cable makes no difference. 73 Gary K4FMX The only time that you need specific lengths of cable between pieces of equipment is to cover up an impedance problem.

[Repeater-Builder] Re: slightly OT: securing feedline to the side of a tower
Andrew is not the only source of hardline hangers. I buy pretty much the exact same snap in hangers with a generic brand name from Talley for about 1/3 the price. skipp Great advice! I know how much the andrew hardware costs... That would bankrupt this project. I ended up going the all home depot route with galv unistrut and strut clamps, minis and my spacing is 8'. I will evaluate the load on the feedline, and add additional supports in problem areas.. Jeff DePolo wrote: Nope, because like you said, they would draw the feedline into the strut, smashing it all up... I regularly use cushioned clamps for attaching rigid feedline to unistrut. I usually buy them from McMaster-Carr, but I'm sure they're available elsewhere. McMaster-Carr has them available in tubing sizes in additional to normal trade sizes- 1 5/8 or 3 1/8 rigid line is really 1 5/8 or 3 1/8 OD. The soft plastic insert prevents the clamps from damaging the line. Here's what they look like: www.mcmastercarr.com - search for 32625T62 However, I wouldn't use them nor mini's (Minearallac-type EMT clamps) on a tower, nor would I use any kind of off-the-shelf galvanized, anodized, any kind of plated unistrut on a tower. The galv on regular electrical-grade hardware doesn't hold up as long as most other tower-grade galvanized structural steel. Valmont makes good hot-dipped galv strut if you wanted to go that route. And as always, use only high-grade galv or stainless bolts, nuts, and other hardware to attach to the tower. Never ever use any kind of plated steel components on a tower. They will quickly rust and become semiconductors, and you will almost as quickly be banished from the site (assuming managed by diligent/competent people). Personally, I'd stick with the real stuff - stainless round member adapters (hose clamps) or stainless angle member adapters (beam clamps), and stainless butterflies or snap-ins. Do it once, do it right. If you make a few calls to local tower companies, I'd bet you'll find someone that either has a surplus that they'll see you at a fraction of the new cost, or maybe even a few 5-gallon buckets of hardware taken down that might still be in good condition and can be reused. As far as spacing between brackets/hangers, it varies with wind speed, icing conditions, and line size. Here's Andrew's chart, based on EIA-222: http://www.andrew.com/search/BN_96221.aspx http://www.andrew.com/search/BN_96221.aspx Most towers around here come from the factory with brackets spaced at 4'. And remember, coax hangers really aren't hangers. They aren't meant to hold the vertical weight of the line - that's what hoisting grips (aka Kellems grips) are for. The job of the hangers is to keep the line from flopping around horizontally in the wind, not to hold the weight up. A properly-installed butterfly is only tight enough to keep the line from moving, not hold the weight. As an alternative to butterflies or snap-ins, on big towers where feedline bundling is a necessity due to congestion and to reduce the windload, the traditional techinque is to install runs of rigid conduit the entire length of the tower (inside preferably), and then using tie wires (12AWG THHN solid) or band it stainless straps to aggregate the lines together around the conduit, again at regular (4' nominally) intervals. Hoisting grips are still used every 200' to hold the weight of each cable individually. Tie-wiring a cable directly to a leg is generally considered bad practice for a number of reasons. First, what do you do when you come to a leg flange? If you hug the cable tight against the flange, the sharp edges of the flange creates a spot for it to wear through. If you form the cable loosly around the flange, it leaves it open for room to move and create new problems that way. Also, by being mounted to the leg, it becomes an obstacle when someone else comes along and wants to attach an antenna mount to the leg. It's also more likely to get damaged by climbers and rigging lines. The list goes on and on... Hope this helps. --- Jeff -- Jay Urish CCNANetwork Engineer http://jay.unixwolf.net Home)972.691.0125Cell)972.965.6229

RE: [Repeater-Builder] NWS SAME Decoder?
I have no idea how the Softronics units work but avoid the Midland branded SAME receivers in ham radio repeater use. The midlands have a design flaw that the Radio Shack receivers don't have. The programmed SAME code opens the squelch, but the midlands then start a timer (built into the firmware), and shut the audio off when the timer expires, even if it's in the middle of a weather alert announcement. The same timer keeps the audio on for no good purpose after an RWT (required weekly test). On the other hand the Radio Shack receivers actually listen for the SAME turnoff code and act properly on it... they actually unmute the audio for the message, and remute it when it's done... what a concept. I was told that one guy modified the RS receiver to insert audio from an external receiver into its decoder section, but I've not tracked him down.

RE: [Repeater-Builder] Chassis mount so-239 with hood?
Dan, Are you making up jumpers in the literal sense, or do you actually need a bulkhead-mount UHF female on one end? If the latter, I suggest using a UHF female bulkhead connector that crimps right to the cable. That way, you can take full advantage of the shielding afforded by the RG-400/U cable, without the leakage of a hood. Ideally, the jumpers in a station cabinet should be point-to-point without any barrels, adapters, or couplings. However, if you really must have the hood, they are available from Mouser. See Item V on this page: www.mouser.com/catalog/630/954.pdf 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Dan Sent: Sunday, June 03, 2007 5:17 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Chassis mount so-239 with hood? Anyone know of a source for these darn things? I want to make up some jumpers. I have the RG-400 coax but I cant seem to find any so-239's with the metal hood over the back! Any ideas? Thanks for your time! Dan/NØFPE
RE: [Repeater-Builder] NWS SAME Decoder?
The new model RS radios work just like the Midland- Timer Based. You want to find the older model RS radios to have it actually shut off at the end of the message. Found that out the hard way.

Re: [Repeater-Builder] Do Anyone Use Their Repeater For This
I experimented with this years ago. I used a Motorola Dimension 2000 (aka BPR-2000) voice pager and an SCom 6K repeater controller. The Dimension 2000 required several parts and a crystal to be replaced in order to bring it down to 147.015Mhz (my repeater output freq.). The original freq was 158.700Mhz. After modification, the pager was extremely sensitive and was able to decode the tones in situations where I could just hear the tones on an HT. Pretty impressive, seeing as the pager has no external antenna. The SCom controller was fairly easy to program after I figured out how to interpret the address on the pager. A touchtone sequence on the repeater would set off the pager. I also programmed the autopatch macro to set the pager off when someone made a phone call. After all this, I decided it was not a practical idea. People were not going to carry around a pager, HT, cell phone, maybe a PDA, etc. just in case an alert was going to go out. It was just too many gizmos to put on your belt. I abandoned the project after having some fun playing with it. 73, Joe, K1ike At 12:11 AM 5/31/2007 +, you wrote: Does anyone out there that is using their repeater to support emergency operations, have it setup to also send out a page to pagers that emergency operators may have.

[Repeater-Builder] EAS Emergency Alert System decoder
I saw a thread about SAME WX decoders. I am wondering if anyone has found a reasonably priced hardware or software decoder for EAS messages. I would like to be able to decode them from our LP-1 local broadcast station. Suggestions? 73 Tim KD7JZ
Re: [Repeater-Builder] Do Anyone Use Their Repeater For This
Likewise, several years ago I experimented with re-crystalling 2 Motorola Spiritone pagers. Pager A went from 35 MHz to 29 MHz worked well, extremely sensitive after changing a few RF stage components. Pager B went from 43 MHz to 53 MHz worked well, extremely sensitive after changing several RF stage components. My RLC-3 controller was able to call the pagers very well. -- Original Message -- Received: Mon, 04 Jun 2007 09:53:23 PM CDT From: Joe [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Do Anyone Use Their Repeater For This I experimented with this years ago.

RE: [Repeater-Builder] NWS SAME Decoder?
Hi Mike, As far as I know, morris softronics has nothing to do with midland radios, 'midlands' is just part of their domain name. Their SAME decoder board allows insertion of any radios audio source, in my case a GE M2 voter rx on 162.4. I know its a little over kill, but hey the rx works good in a high IM site :) It has a couple of control bits to and from the card for wx alert status and on/off over-ride control of the wx audio. Those tie into your repeater controller of choice. Its serially rs-232 programmed for the SAME codes of interest. 73's Ralph W4XE -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] Behalf Of Mike Morris WA6ILQ Sent: Monday, June 04, 2007 6:30 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] NWS SAME Decoder?
