Re: [Repeater-Builder] MSF5000 Squelch
Great info and just what I needed. Thanks again Bob! Adam N2ACF Bob M. wrote: You've got several more hours (or even days) of reading ahead of you! Thanks for the comments. The MSF5000 squelch is a single-level noise-based squelch system, much like the MaxTrac and most mobile radios. The squelch-tail duration is fixed. However there are two distinct and electronically different squelch circuits in the station: one for the Repeater, one for the Receiver, and they are independently set via EEPots. To confuse matters, the Receiver squelch can be set from the front panel Squelch pot instead of the EEPot IF the Acc Dis switch is raised. The only official way to tell if the squelches are closed is with a digital metering panel, as it has LEDs on both squelch signals. You can also measure the squelch circuit outputs with a DC voltmeter. The station's CW ID will NOT fire if either squelch circuit fails to close. Whichever way you're not using the station (repeater or receiver), then set its squelch EEPot to 99 or some high setting to insure they both eventually close.

Since the original post referred to a CXB station, the operation of the squelch circuitry in the SSCB is as follows: The receiver squelch switching circuit operates in two modes. With a weak signal just above the opening sensitivity, squelch closing is slow (approximately 150 ms.) which results in the long squelch tail heard at the end of a received message. The long squelch tail is present to prevent the received message from being chopped during a weak fluttering signal. With a strong signal (approximately 10 dB above opening sensitivity), a squelch closing occurs immediately after the end of a received signal. This prevents the squelch tail from being heard. ... The repeater squelch detector circuit is very similar to the receiver squelch detector. (repeater slow squelch closing time is approximately 200 ms.) Yahoo! Groups Links

Re: [Repeater-Builder] WX-200 with CAT-1000
Mike, I'm doing just what you want but not with a CAT1000 but rather an SCOM 7K. I have the audio from the WX200 being fed into one of the three ports on the 7K and have made that port the lowest priority. This way, we receive all of the weather reports from the WX200 but if someone has an important transmission, they can talk right over it and the controller priority by port does the rest. It works perfect. Last night in my area of New York, we must have received a dozen watches and warnings for severe lightening. Everything worked flawlessly just like you desire on your system. Does the CAT1000 let you prioritize ports? Adam N2ACF At 20:59 6/16/2008, you wrote: My club is considering the purchase of a WX200 to go with our repeater/CAT-1000.

[Repeater-Builder] SpectraTac Housing - SMA Connector?

Hi Bob, Thanks for the reply. I too didn't think that there was anything special about the cable or connector.

Adam N2ACF At 15:06 4/24/2008, you wrote: I don't think there's anything special about the connector or cable. You can just buy a regular straight SMA male (crimp or solder) for RG400, use a short piece of RG400, and attach it to the existing N-female chassis socket. Or make/buy a short SMA to N-male cable and install a bulkhead thru-connector, N-female to N-female, in the chassis. There should be room for that much. There are plenty of places on the web that will make any custom cable you want. You tell them what connectors you want at each end, the type of coax, and the length, pay about $30, and you get a very nicely made cable. The cable in my 900 MHz chassis is maybe 8-10 inches long and is arranged in the shape of a 2 with a tall tail at the top that is soldered to the N-female connector. There is an official part number for the entire cable assembly in the manual, but I doubt Motorola would have it any more, or if you'd want to pay them for it.

You should be able to bypass the 12v to the audio PA on the regulator board as it only feeds the audio PA to the best of my recollection... It does indicate a problem if 2 IFAS boards do it, but in the bigger picture it is an unused circuit in a voter rx, so it may be easier to move on... If the caps are weak on the 12v, it could just be allowing the audio PA to be unstable as there is a feedback loop in the windings of the audio PA transformer and if power is unstable it could become an oscillation and be what you are seeing run off and blow the fuse The mod I described is on older IFAS boards and eventually became incorporated into new boards, swapping the component in the feedback winding of the transformer.. Off hand I think it was a cap to ground which was changed to a resistor to ground... and it stopped oscillation in the circuit... The LBI's are RB website, quick and dirty may be disable the 12v to the audio finals and it should draw a lot less current. It also seems to me one of the audio pa transistors was tab ( collector ) hot and maybe the hot tab mount insulators melted causing the 12 to short to ground of the heatsink... if you have a direct short, start there... but 2 IFAS boards doing same... is curious... ohming 12 v to ground on the IFAS side of the fuse would tell if you have a direct short or a current run-away or similar...

[Repeater-Builder] Recommendation - Vane Switch
Hello All, I'm looking for information from anyone who has experience and could recommend a good vane switch to be installed on several repeaters. Some of my machines are 2 1/2 hours from my house so visiting them often just doesn't happen. I would like to install a vane switch to monitor the PA Fan and connect the output of the switch into the sites SCADA system. Manufacturer, model #, price, and opinion would be greatly appreciated. Thanks! Adam N2ACF
RE: [Repeater-Builder] Re: Recommendation - Vane Switch
Thanks guys for the interesting thoughts. All 6 of the PA's are solid state. They are the Quintron / Glenayre 90 watters. At 12:46 PM 7/23/2007, you wrote: If the blower is used to cool a tube pa the thermostat detection hardware is probably way to slow. I was assuming a SS PA, but maybe that was a mis-assumption. Many vane indicators are of the long arm micro switch type. Easy enough to make your own but you can probably find them through companies like McMaster, CH Sales Company, Grainger (all in Southern California) and many Heating Air Conditioning Supply Stores. I hate vane switches, having seen way too many failures over the years. Vanes breaking off, microswitches getting stuck due to all of the gunk that accumulates, etc. Good transmitters use differential pressure sensors to measure the difference between the two halves of the tube compartment. Too much differential and you've got a blockage in the tube fins or socket. Not enough differential and either the blower isn't running, the intake filter is clogged, or the chimney is blocked. I always monitor stack temperature too as a backup. For a SS PA, I still think a thermostat is the most reliable. I had a 5kW watt FM transmitter that somebody bypassed the air interlocks on. The squirrel cage blower lost a blade and jammed up. Looked like a miniature version of Cheryobyl in there after all was said and done...and off to the scrap yard it went (it was 30 years old and due for retirement anyway). --- Jeff Yahoo!

Re:[Repeater-Builder] SpectraTac receiver on 12v
I could be mistaken, but another reason why it would be easier to just replace the caps is that I think you will then have to find and disable the emergency power alert tone if you go direct to 12v. Unless you completely remove the supply that is. Adam N2ACF - Original Message - From: Bob M.

Easier to fix it than to bypass it. Unplug the power to the unit. Unplug the cables going to the cardcage backplane so you can get the back cover off. The back cover is held on with four screws. There should be two screw terminals on standoffs coming off the power supply board; these are the 12V battery backup terminals. They're very close to the voltage adjusting pot on the board. The station should work just as well on battery as on AC. It would be better to replace the bad caps. However, you probably won't find exact replacements available any more, especially for a big aluminum can capacitor. I have a full manual on the SpectraTAC receiver. I could send you the schematic, board layout, and parts list if that would help. I can either scan them and put them up somewhere, or make copies and mail them to you.

The 8381 is the small fat reed used in the Motrac, Motran and Micor PL decoders. The 6209 is one of the small thin reeds, and is factory spec'd as the decode reed in Mitreks that use reeds (there were two tone boards for the Mitrek, only one used reeds). The fat reeds were about 30% thicker than the thin reeds, and it makes a difference: if your decoder expects a fat reed and you plug in a thin reed you get less coupling and it can cost you some decode sensitivity. There are some thin reeds that will work in place of an 8381 but not all. It depends on the decoder and the reed.

If you want to use discriminator audio and de-emphasize on the controller, you need to change R19 to 510 K, change R20 to 51K, and install a .0068 uf cap in location C10. See page 2 of the schematic. Regards, Jeff At 05:43 PM 4/17/2004, you wrote: Hello All, Today, I fed the remote base receive audio input of an NHRC 4/M2 with descriminator audio from a Motorola Maxtrac. I'm taking the audio right from the 16pin accy plug on the radio. When listening to the primary port of the controller, the remote base audio seems a bit high pitched and not rolled off enough. Has anyone else experienced this on this controller or perhaps I'm doing something wrong? Any help would be greatly appreciated. Thanks! Adam N2ACF Yahoo! Groups Links Yahoo! Groups Links Yahoo!

[Repeater-Builder] 900mhz Spectra Tac Receiver
Hello All, I sent this to the AR902 list with negative results so I thought I might try here as well. I have acquired a Motorola 900mhz Spectra Tac receiver. I also have the service and tune up manual as well. However, the manual only covers the low band, VHF, UHF, 800mhz receivers. Does anyone happen to have the tune up procedure for the 900? Any help would be greatly appreciated Thanks! Adam N2ACF Yahoo!

Re: [Repeater-Builder] 900mhz Spectra Tac Receiver
Hi Russ, Thanks for the reply but I think that you may have misunderstood me. I'm seeking information on the tune up procedure for a Micor Spectra Tac receiver, not the Spectra mobile. My book has every band except that one. Thanks anyway Adam N2ACF - Original Message - From: russ [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Thursday, April 01, 2004 8:15 AM Subject: Re: [Repeater-Builder] 900mhz Spectra Tac Receiver We have 9 Spectra's all the info came from the Bat Labs web site (www.batlabs.com) I think is the url. Most help full on the 900 MHz stuff. Remember most if not all of the 900 stuff is norrow band (2.5 KHz) Not 5KHz like two meters. We are useing all 2.5 on the Metro-Comm system so we will not have to convert every radio from 2.5 to 5 kz. Just works out better that way. If you need some one to covert it down to 902 to 927 contact me off line. ([EMAIL PROTECTED]) I will pass the name and phone number along to you of the person who does most of the work for the folks (users)on the Metro-Comm system. 73 Russ, W3CH Trustee W3PS Metro-Comm, INC repeater network. - Original Message - From: Adam C.

[Repeater-Builder] M6709 vs. M7716
Kevin All, I have a Micor SpectraTac Audio Squelch Card with a blown up M7716 IC. I have the older version chip as a replacement, the M6709. Will I see a difference in squelch performance from the new chip to the old? It's the only replacement that I have. Thanks! Adam N2ACF Yahoo!

Re: [Repeater-Builder] Re: Interference Found!
Ken, I went back to the site today. There are absolutley NO markings of any kind on the box. Wow, that thing has some signal on 147.457!! It's really killing my input. Anyway, thanks for the help. I'll be making some phone calls tomorrow morning. If you don't mind me asking, what do you do for Verizon? Would they get you involved in soemthing like this? Thanks again..

Hi Adam, The person you should try to get in contact with at Verizon would be the Outside Plant Engineer for your area. Can you email me some information such as the location of this Light Span box? I can try looking him/her up on the company website Monday. Ken --- In Repeater-Builder@yahoogroups.com, Adam C.

Rest assured, every cent of the cost of correcting this interference problem will be paid by Verizon, not you. It will greatly help your case if you can show that the offending carrier is at 147.457 MHz, and is not the result of an image response in your receiver or of IM occurring in a poorly-designed receiver's front end. It will also add credence to your complaint if you can use repeatable T- Hunt tactics to pinpoint the source of the carrier to a specific antenna or cabinet. Take note as to whether or not the carrier is modulated and/or identified in any way, and whether it is continuous 24/7 or intermittent. Turn off all of your equipment before making these searches, just to be absolutely certain that the carrier is not generated within your own repeater. Many receivers, and a surprising number of controllers or IDers, generate birdies that render certain frequencies unusable. Be certain your own equipment is innocent before filing a complaint. Of course, you had better be certain that Verizon is, in fact, the offender before pointing a finger at them! If your repeater is officially coordinated, your case is even stronger.

[Repeater-Builder] Interference Found!
Hello All, Back in September, I sent out a message asking if anyone had any interference experience with the 2 meter pair 146.460 / 147.460 as I have a constant carrier on my input. I didn't really receive any substantial replies and have been looking for the source ever since. Yesterday it was found! My input (147.460) is being crushed by a Verizon Light Span which is mounted in an outdoor enclosure at the site. It is emitting a strong carrier on 147.457. Does anyone have any experience in dealing with a company like Verizon who I assume is NOT really too RF savvy? I believe that the equipment inside the box which makes up the Light Span is manufactured by a company call Nortel, but I don't have that information confirmed yet. Any help and guidance would be greatly appreciated! Adam N2ACF Your use of Yahoo! Groups is subject to http://docs.yahoo.com/info/terms/
