Re: [Repeater-Builder] An interesting squelch problem
If the Micor Squelch Chip is driven with a bunch of audio, the inverse of the normal situation happens. I'll explain; lets say you have a perfectly working Micor receiver or a receiver with a Genuine Micor Squelch fashioned to it. Now, turn the squelch until it just closes and one little 'youx' more. When your receiver is hearing a signal that has good quieting, remove the signal; the squelch closes very quickly because the amount of squelch noise presented to the squelch chip was much lower than normal wide open squelch noise. Now, input a noisy signal into the receiver and do the same thing, unkey and alas a squelch burst before closure. Now, take your perfectly working Micor Squelch and wind the squelch pot a bunch tighter, maybe clear tight, and input a full quieting signal then unkey. What? You hear a squelch crash? Yes, you will. Why? Because at this point you are feeding a bunch more noise into the squelch chip than it needs to operate, and it's confused. It thinks the quiet signal is noisy because the squelch pot is mis adjusted from where folks would normally run it. This is a feature of the Micor squelch, and you can't do anything about it. Try re-setting the squelch control to just close and a wee little more and see if proper squelch action doesn't return. Let us know your result.

RE: [Repeater-Builder] Help with Wacom WP-639 Duplexer
All Today I have spent a couple of hours sweeping the cavities and come to the conclusion that they are all high pass low reject. (Originally of tx152 rx158) Looking at the cavities 25mhz either side of my desired frequency RX145.1625Mhz TX 145.7625Mhz I can a second notch but this never comes within 2Mhz of the pass with the invar rod all the way in. They tune perfectly for pass high notch low. So it looks like I have a set of useless cavities unless anyone knows what the physical difference is between the High Pass Low Reject and High Reject Low Pass. Can I make any modifications?

A friend has attempted to align the filters but is having problem aligning the notch down to 145Mhz.The problem he tells me is he can only get the notch down to 148Mhz with the Invar rods pushed all the way in. He has made up new patching loom and still the same result.Has any body played with these and could offer any advice? Have him swap the ports and try again, in other words, tune the duplexer backwards from the way it is presently tuned using the opposite sides for the receiver and transmitter. Minimum frequency separation happens with the rods all the way in, which leads me to believe he is attempting to tune the duplexer upside down, on the 'wrong' notch; there are two notches, as explained below This article explains the basic principal for the Wacom WP-641 and 639 style pass notch network. While specifically written about the 641, the effects are the same for the 639, however, the notch depth won't be as deep with the 639 as what is stated in the article: http://www.repeater-builder.com/wacom/wacombpbrnotes.html Complete tuning directions are available from this page: http://www.repeater-builder.com/wacom/wp6xxVHFtuninginstructions.pdf If you still encounter difficulty after attempting the switch-a-roo, email us back Kevin Yahoo!

The duplexer was likely set up as a "wide spaced' unit since you have passed the original frequencies along. The notch spacing from the pass is determined by the length of the center conductor in the notch stubs. These center conductors will likely need made longer to get the spacing closer. This center conductor is usually simply a length of brass rod soldered into the connector. Also, depending on the depth of the line boring in the dielectric rod, it too (the depth of the bore) might need to be deepened, but try the rod lengthening first. Let us know how you make out.

[Repeater-Builder] Re: Mitrek PL Deck
Hi Ken, Did you get your Dayton picture I Emailed in? If not maybe Kevin will send you a copy. Anyway, working from memory... the dual reed mitrek board will duplex, but it took a bit of work. You just need stare at the circuit for a while to figure out the mods. You can also populate some models of the single reed board for duplex operation. One trick is to add a com-spec encode or decode module. Some of the T/R Logic will have to be modified... but it will work duplex. Another side-bar. The encode/decode chips are the same as used on the MSR-2000 pl board. They do have different part numbers. Ken Arck [EMAIL PROTECTED] wrote: We're talking an HLN-4020A, dual reed type.

What happens when the repeater is idle for a while, and then the whole unit goes below the dew point. :-P Passive water cooling makes sense to me. We're looking at a 100W UHF system here, that I just might use it on. Similar setup to existing systems, I won't run the water pump 24/7, I'll turn it on after the repeater has been keyed up for 30 sec or so, and then shut it down after a few minutes of idle, along with the cooling fans. Pull a slight vaccum in a static tube that runs up above the system, and then any leaks pull air in, not let water out. The drop in vaccum triggers an alarm. For an inaccessible site, I think it's probably a bad idea though, at least with current technology. Yahoo!

Hi yes I found the link, but it is a phone number to ring in the States, I don't think so from the UK :-) Anyone got an email for Ted Jansen ?, the guy who does the GE Manuals. I expect the sets this week and no way am I just going to dive in without knowing what does what, I fix too many sets were people have done that. Many thanks for the suggestion. 73 Steve - Original Message - From: ian.ashford To: Repeater-Builder@yahoogroups.com Sent: Saturday, June 04, 2005 11:48 PM Subject: Re: [Repeater-Builder] help, wanted Steve, have you tried this : http://www.repeater-builder.com/ge/gemanuals.html (From the repeater builder website) Ian G8PWE - Original Message - From: steve To: Repeater-Builder@yahoogroups.com Sent: Saturday, June 04, 2005 9:43 PM Subject: [Repeater-Builder] help, wanted Hi again surely someone in the group either has or knows were I can obtain a service manual fr the low band GE Rangr.

[Repeater-Builder] Simulcast: Anyone done this for ham repeaters
Has anyone implemented a simulcast (multiple TX's on the same channel) system for a ham 440 repeater system? It looks like you have to have TXCO's capable of tracking within a few hertz of each other. You can't do this with standard TCXO's, so I'm wondering if anyone has tried modifying a TCXO to lock to a GPS source, or NTP source. Steve WA6ZFT Yahoo!

Re: [Repeater-Builder] Questions on Kenwood TKR-750 Repeater
Try using a real repeater antenna like a DB-224 with 1/2 hard line type coax. The Kenwood TKR disclaimer says you need to install a circulator on the repeater out put. If you e-mail me direct I will send you the Kenwood disclaimer back to you direct.

Unfortunately we can't hear anything beyond one kilometer. Here are the frequencies we are using: TX 15900 RX 16000 TONE1413 The equipment are being used in africa in a remote location for an NGO helping refugees. I am back here in the states now.

Re: [Repeater-Builder] Simulcast: Anyone done this for ham repeaters
Steve, I'm experimenting with that concept on VHF, duplicating an identical installation in my county's public-safety UHF system. Although I am using the Kenwood TKR-740 repeater, the county system uses Kenwood TKR-840 and Motorola MTR2000 repeaters with Hewlett-Packard/Symmetricom GPS-disciplined oscillators that provide phase-synchronous 10 MHz reference inputs to the repeaters. Both of these repeaters come standard with 5 or 10 MHz reference inputs. Once you have multiple transmitters constrained to 0.01 Hz of their assigned frequency, you need only account for differences in audio phase and delay. Of course, this is much easier said than done, but the ready availability of GPS frequency standards on the surplus market makes the application achievable for Hams. Even so, a simulcast system is not a cakewalk to design, and the system can crash profoundly if one of the transmitters loses its GPS synchronism, so multiply-redundant components are advised. 73, Eric Lemmon WB6FLY Steve Rodgers wrote: Has anyone implemented a simulcast (multiple TX's on the same channel) system for a ham 440 repeater system?

Re: [Repeater-Builder] HJ9-50 loss
5 Air Dielectric HJ series Loss per 100' 50 MHz = 0.0547dB 150MHz = 0.0981dB 300MHz = 0.143dB 450MHz = 0.180dB 800MHz = 0.250dB 960MHz = 0.278dB 960MHz is the highest usable frequency because the inner conductor to outer conductor distance.

Re: [Repeater-Builder] HJ9-50 loss
Thanks for the quick reply. I couldn't find that anywhere on the net. I have a guy who is telling me that 0.34 dB (at 900 MHz) is too much loss on a SCANNER antenna run. LOL! I'm going to ask him if I should use HJ9-50 instead. ;- Although I have no idea how I could connect it to the antenna! I guess I could just connect it and not worry about the support mast! Joe M.

Re: [Repeater-Builder] HJ9-50 loss
Why is that? Does the feedline start acting like an antenna (or dummy load) when the conductors are 1/4 wavelength apart or something? Joe M.

Re: [Repeater-Builder] HJ9-50 loss
Exactly. For example 1 5/8 hardline can't be used for 2.4GHz, but 7/8 works fine. On 6/4/05, mch [EMAIL PROTECTED] wrote: Why is that?

[Repeater-Builder] Micor mobile repeater - no audio?
Hey gang, I've got a "Repeater Builder" UHF micor converted mobile repeater running great for several years.. Last week sometime it stopped passing audio.. dtmf, etc... I can key it fine from places like usual, but it doesn't seem to pass any audio.. Would this be more of a controller issue or possibly something awry with my micor?Its running a CAT250 controller. Comments appreciated ofcourse. Rod NJ Yahoo!

[Repeater-Builder] Re: Remote monitoring of repeater site
You should also check out MAC+ or Mini-MAC+ - made by a company called Comlab. (www.comlab.com) I would say they are state of the art. I'm familiar with both Comlab and Protek, and for my money Comlab has the edge right now. Depending on the size of your system/requirements, multiple digital analog inputs, and relay outputs, and probably even more that I'm not familiar with. True: Have actually had instances of a Protek on a system; power amplifier starts to go soft, and pages me out. Before the end users can notice a problem in coverage, I'm on the phone to alert customer contact what's going on that I'm on my way to take care of it before they go completely down. It's very impressive, but you do want to be careful what you're monitoring, and how you set your trip-points, and be esp. careful of 'false positives' - alerts that come to you when there's nothing really wrong; it can be easy to get complacent if you don't investigate WHY you're getting alerts that are wrong. Granted, that's better than NOT monitoring something that IS important! I'm by no means an expert on their applications, but I am sold on their use, especially in a critical system.

Comments appreciated of course. I'd check and see if audio is present going into the controller with a scope. If it's several years old, it might have a MicorMuteboard installed. If so, the LM-386 might have gone bad. This would be a 8 pin dip IC on a little board. Replacements might be obtained from a local Radio Shack. Do you hear the controller responses okay, like courtesy tones, etc? If so, at least part of the controller and transmitter are likely okay. Kevin Custer Repeater Builder Yahoo!
