[Repeater-Builder] Re: ENHANCED RECEIVE
Most of the replies so far indicate a failure to read the original post *SLOWLY*. TWO preamps, one after the duplexer and then another one after a pass-reject cavity. This sounds wrong to me under any circumstances. The pass-reject cavity should have at most 1 or 2 db of loss, adding yet another preamp to the chain is going to do nothing other than decrease intermod performance. If it were me I'd lose the preamp between the duplexer and the cavity and keep the one between the cavity and receiver. Additionally unless I was trying to reject a specific signal other than my repeater's transmitter I'd use a plain pass cavity rather than a pass-reject to get better selectivity. If a pass-reject is needed for the repeater's transmitter you really need to upgrade the duplexer. 73's Skip WB6YMH --- In Repeater-Builder@yahoogroups.com, k2aau k2...@... wrote: I have heard of repeater owners using pre-amps on the receive side of the duplexer and adding 1 pass-reject cavity after the preamp and placing a pre-amp on the pass reject cavity to enhance more receive.

(Yeah I know, welcome to the real world!) Can someone tell me in basic terms what is the difference between an isolator and an intermod suppression panel which contains an isolator? If one has a high power tube PA on a repeater, I assume he would need to use a high power isolator or intermod panel after the PA? Or would it be sufficient to use a lower power one between the solid state exciter and tube PA? Thanks... Paul N1BUG The isolator prevents power from the antenna from entering your transmitter where it can mix with your output and cause intermod products. In the process of doing this the isolator also generates harmonics of your transmitter output so you *MUST* also use a cavity between the isolator and the antenna to suppress the harmonics. An additional benefit of an isolator is that it protects your transmitter from a damaged antenna system. If the antenna has 100% reflected power all of that power will end up in the isolators load so plan accordingly. So no isolator between the exciter and the PA does no good at all in preventing intermod. 73's Skip WB6YMH

The delays inherent in VoIP linking will drive you nuts if you are duplex and listen to the repeater output while you are talking, but since you are talking about a 6 meter repeater I doubt that will be a problem for you.

As an inter-site link, I was thinking of using some sort of VOIP arrangement via the internet. I'm curious if anyone has tried something like this: My idea is to use a point-to-point, private link (i.e. not IRLP or Echo) to pump audio and maybe even some signaling between sites. The receive site would consist of the receive radio, controller (most likely an Arcom), and a PC to do the encoding/streaming. The transmit site would consist of a PC to decode the audio stream, a PL decoder for TX logic, and the TX radio. The basic premise would be to take audio from the RX (PL filtered), fed thru the controller, mixed with link PL, and fed to the PC's audio input. The PC then streams the audio over the internet to the RX site PC, where it is decoded and fed to the TX radio, which will be keyed by a PL decoder (provided the IP encode/decode process hasn't mangled the PL). Whew... Now, question is: will it work? Or more properly, has anyone made this work? I'm going to try it on a small scale just to prove concept, but I'm curious if anyone has tried this already. My intention is to use something along the lines of Winamp with Shoutcast or Windows Media Encoder to stream the audio. I'd rather find a Linux-based CLI encoder if such an animal exists. I had thought about using IRLP nodes as endpoints, but IRLP policy would preclude that. Thoughts? Encouragement?

[Repeater-Builder] Re: software repeater controller
Hi Bob, what I mean is that when building this system a few years ago, I tried several different operating systems with varying degrees of success. I tried Win95, Win98, WinME, Win2000 Pro, and WinXP Pro (first generation). With every operating system except WinXP, I had to find and install drivers for each of the sound cards. 3 of the cards are Soundblaster PCI models, and the fourth is a SoundBlaster ISA unit. The problems I experienced ranged from interaction between the individual mixer controls of the different cards to occassional computer lockups. In contrast, when I tried WinXP, it picked up ALL of the sound cards during installation and I didn't have to install any drivers whatsoever, even for the old ISA card. And, it placed all cards correctly within the sound devices system, assigned mixers, and I have no interaction between them at all. Of course, this is just my experience with my particular computer hardware and your milage may vary. - Darrell/KA7BTV For multiple audio ports these days I'd recommend using USB audio devices. ISA slots are way gone and PCI slots aren't far behind. For an embedded PC controlling radios 24/7 you want something small, quiet and low power, most form factors that fit that description usually have few if any PCI slots. Linux has no problems handling multiple USB audio devices and I'm sure Windows will as well. I've personally used 3, but have read reports of 8+. In addition to audio you'll need PTT and COS/CTCSS sense inputs and outputs and some USB audio chipsets also provide general purpose I/O pins that can be used for that purpose. DMK Engineering makes a USB device called the URI (USB Radio Interface) specifically for interfacing radios (http://www.dmkeng.com/Products.htm ). You may be interested in my VoIP/Repeater controller project called thelinkbox: http://groups.yahoo.com/group/thelinkbox . It's an open source project that runs on Linux.

Frequency coordination boards have no power to get Joe to take his repeater off the air because he doesn't use it enough. In reality when the local frequency coordination group won't/can't do anything most (but not quite all) groups will eventually pick the most likely pair and set up shop on it without coordination. If Joe's group is truly dead they'll be all set. More likely Joe's group will come back to life and make noise. If it's a lot of strong noise the new group will probably pick a new pair and try again. Three points: 1. USE IT OR LOSE IT! 2. We need ACTIVE frequency coordination boards even when all pairs are gone. A frequency coordination council that's nothing more than a bit bucket does no one any good. 3.

Or why users need to command remote repeaters. How often is something like that really used? So which is it, you don't care or you are generally curious? Ok, I'll take a whack at some history that may help you understand where this site prefixing concept came from and why. Hopefully I don't screw it up too badly as I was just a high school kid at the time who was in major awe of the wizards. The site prefixing scheme originated in the days of TTL control systems long before microprocessor based commercial systems existed. My understanding is that Alan Burgstahler, WA6AWD, originally conceived the concept in the very early days of repeater linking (late 60s, early 70s). Alan and Robin WA6CDR linked two existing UHF machines that both had control systems that were originally designed without linking in mind since no one has thought about it yet. The problem: how do you control one machine from the other? Alan came up with a hardware solution called a prefix decoder. This was a PCB with a few (three I think) 88 mH toroids, a few caps, transistors and chips. The prefix decoder decoded just enough tones to decode exactly 3 touchtone digits. When the prefix decoder saw the magic 3 digit sequence it switched the control system from the usual UHF receiver to the link receiver for a while to allow the link to control the machine. Simple, efficient, easy to use. Second problem: How do you keep random touch tones originating from remote 2 meter base stations from accidentally controlling the system? The desire what only UHF control operators be able to function the remote system. Again this was 197x, what would you do? The simplicity and elegance of the solution still strikes me with awe: When the prefix is received the prefix decoder generated a telephone dial tone back down the link. This served two purposes: One the UHF control operator knew he has successfully obtained the remote systems attention and that it was awaiting his commands. And secondly (perhaps more importantly) any 2 meter users trying to muck with the system were immediately stopped in their tracks since the hilltops 2 meter transmitter was now keyed by the dial tone. I'm sure there were other ways to do it even in the 70s. I happen to think the prefix solution was an excellent one. 73's Skip WB6YMH

(GRIN) Here's a way to do it. I don't know what number of macros you could get away with, but probably enough. I'm too tired to look up the limits and do the math. First off, on all sites... SITECODE12345* does something on a specific site and these macros are always active and programmed separately into specific controllers. Next, set up a hidden start-of-activity macro on all controllers on only the local user port's receiver (RX1) that renames macros stored in parking macros to the local macro commands that users would use locally. The parking macros are unpublished. Example, A12345 gets renamed 12345, and A23456 gets renamed 23456. A12345* (and it's cousin, the renamed 12345* whenever local user activity is present) is a macro that calls the local repeater's SITECODE12345 macro. During local commanding, other repeaters in the network will be listening for the parking macros and won't respond to the command. Only the repeater(s) with active RX1's will respond to the local commands. Then an end-of-activity macro calls a 2nd hidden macro that names all local macros back from their new 12345 to A12345. Now, obviously that leaves a problem... if two repeaters in the network are both keyed on their user inputs when a so-called local command is executed, both will respond. To make this more robust... You tell end users that All commands are available by typing the sitecode and the command on any repeater. However, if you don't want to type the sitecode, press 1* plus the command on your local repeater. In this case, you set up 1* to mute DTMF. Your end-of-activity macro now must both copy the local macros back to parking and unmute DTMF. (In fact, if you do this you don't need the start-of-activity macro at all, but I like that one better. You could have *1 do both setup of the macros and the DTMF mute.) To make this work, the default * as enter key option in the S- Com, must be on. This is so users don't even have to unkey to have the 1* execute. The users don't have to know the preceeding 1* is a separate command. They just know to prefix any local simple command with 1*. If they hit 1* and drop key, the local controller will immediately revert back to only responding to the SITECODE commands, and unmute DTMF, resetting everything back to the state where any machine in the system can respond to either a local or remote SITECODE prefixed command. -- Nate Duehr - WY0X [EMAIL PROTECTED] Nate, Renaming macros whenever the mobile input is active would cause all link command ability to be blocked as the macro numbers the link is looking for are currently non existent. For the majority of the time, this would not be a big problem. If however there is a problem with the mobile input receiver (RX1) on a site from either a failed receiver or a problematic user sending unwanted transmissions, you would not be able to resolve the issue from a distant repeater via the links. Processor load could become significant if you have lots of macros that need to be renamed every time the mobile input COS goes active or inactive. What happens to the poor processor when a signal is picket fencing or a 'fly' decides to intentionally send short on and off transmissions (rapid kerchunking). The whole idea of implementing pre-access or prefixing is to emulate the functionality of the public telephone network command structure (not exact, but similar to the simplicity of dialing a phone). Anywhere you go within the system, dialing a local number (sending a local command) gets connected to a local client (if the number is valid). Access to that same local number from outside the local area code (a different repeater) is accomplished by simply adding the area code (site prefix) to the desired client number (command sequence). Simply adding command prefixing on a per port basis resolves all of these issues. This method also allows all commands to always be available to all ports. Each time the port specific pre access DTMF sequence is received, the following DTMF digits are processed during that specific transmission. Ed Yoho WA6RQD

Well if you want to add a VFO mode to a true boat anchor of a radio I designed a code plug replacement for Syntor X called the xcat that does just that. It gives you complete control of all Rx and Tx frequency as well as PL and DPL encode and decode, scan list, and even the transmit timeout timer. You can scan for PL or DPL codes or scan between limits for signals. The primary purpose is to interface Syntor X s to repeater control systems, but you can also talk to it with a Windows program and a Com port. Small, light and convenient the Syntor is not. Bullet proof it is. 100 watt low band (10 6 meters without retuning) and 2 meter Syntors Xs go on ebay for $50 frequently. Shipping and accessories are another matter. UHF Syntor Xs are fairly scarce.

[Repeater-Builder] deviation meter in Motorola test set?
I just picked up a S1059B Motorola test set at the swap meet yesterday that has the peaking generator and deviation meter panel options. I'll probably never use it, but I'm curious how the deviation panel is used. There are BNC connectors on it for an antenna and OSC. I'm assuming the peaking generator is jumpered to the deviation panel for use as a local oscillator. Did I guess right, do I get a fish biscuit? 73's Skip WB6YMH

[Repeater-Builder] Syntor X and DPL
W9TS and K7IC and others have reverse engineered 99% of the Syntor X's code plug (http://home.xnet.com/~pakman/syntor/syntorx.htm). The reason I say 99% and not 100% is that KB8ZQZ discovered that some non-Motorola radios (specifically his Yaesu VX-5R) wouldn't decode the DPL generated by the Syntor with bits 0-2 of byte 5 set to all ones as documented. He also discovered factory programmed code plugs that didn't have the all ones setting. By experimentation Dennis found the bit settings that worked with his Yeasu and incorporated his findings into his excellent syntorxgen program (http://msuarc.egr.msu.edu/syntorx/). A lot of codes worked with more than one setting of the funny bits (what Dennis calls bits 0-2 of byte 5) and he picked the one that worked the best on his HT for his program. This is were I came in. I'm in the process of adding DPL support to my xcat project (http://groups.yahoo.com/group/xcat) and I used Dennis's code as a base. Unfortunately on the air testing was less than successful. The first code I tried (365) worked fine, but the second code (245) failed to be decoded on an Vertex 5000 repeater with a Pacific Research controller. After some head scratching I tired changing the funny bits and found that 0 worked. Dennis's table (http://msuarc.egr.msu.edu/syntorx/dpl_sparebits_data) showed that 0 also worked with his Yeasu. The documented all ones setting for the funny bits did not work either. So here's the pitch: Is there anyone that has access to a suite case programmer with Syntor X support that is willing to generate some test plugs? I'm interested in documenting the golden setting of the funny bits as generated by mother Motorola herself. Hopefully this information will allow code plug data to be generated that will work with radios from other manufactures. Dennis's testing confirmed that the bit patterns in factory generated DPL code plugs he's seen were decoded successfully by his Yeasu. I don't need the code plug themselfs, only the data pattern generated. If you have the equipment but don't have a code plug I'll give you one. Thanks 73's Skip WB6YMH p.s. I apologize for cross posting, the other lists I posted this message to have very low traffic, but are specific to the Syntor audience.

[Repeater-Builder] Re: Kinda of a strange question
You beat me by a couple of years. I built a 22S control system from TTL that was on Palos Verdes and then later on Onyx Peak (9114 feet). The original controller used octal to set the actual N code into the 22S, but I later added a 2708 lookup table. *52 put you on 146.52, *34 put you on 146.34/146.94. Since it was all done by a lookup table it knew the band plan and would automatically select a repeater split if you dialed an input frequency or simplex on the output if you dialed an output frequency, etc. It did the right thing if you dialed *40 (people from L.A. will know that frequency). There were commands to force simplex or reverse. I can't find the schematic any longer, but I did find a control list dated 12/79 that was after the lookup table was added. My best guess is 1/79 when it first went on the air. I know my controller wasn't the first 22S controller as I later compared nodes with Greg (WB6KCD ?) who that had built a controller before I had. It also had cw unkey telemetry that sent the frequency in cw when you unkeyed. I can't tell you how sick I got of hearing 46 and 52 in cw over and over and ... It sounded like a good idea at the time. Boy those were the days ... we had the only ham box on Onyx peak for a year or so and could hear 3 states ... then a 2 meter repeater was installed. The 22S rolled over and died whenever the repeater keyed up (duh!).

I had to use the input filter on the TS-64 and it started to work as good or better than the /\/\ decoder did. The discriminator audio has a lot of low frequency noise that was causing the decoder to delay the decode about 400mS. After the filter was used in took less than 100mS to decode. I have not had a single problem after doing that. Charles Miller. Sorry, I don't follow. You had to use what input filter? 73's Skip WB6YMH Yahoo!

This may allow the decoder to false on some noise patterens, and this is why the original design has the longer decode time. You may want to try different values to get the best timming for your application. Basically a R/C timing circuit. The component changes listed the web site for quicker decode are for a TS-32, not the TS-64. Comparing the schematics leads me to believe the mod doesn't apply to the TS-64 at all. The TS-64 is a micro based design, the TS-32 is a discrete design. 73's Skip WB6YMH Yahoo!

[Repeater-Builder] ts 64 pickup time?
I've recently added a ts64 to a 2 meter Micor repeater and have noticed that the PL decode time is noticeable, probably between 1/4 and 1/2 second. I'm use to Motorola PL decoders that have no noticeable pickup time. The ts64 decode seems to be solid with no problems talking it off. The input is right off the Micor's discriminator. Is this normal or do I have a problem? It's certainly an effective kurchunk filter! 73's Skip WB6YMH Yahoo!

[Repeater-Builder] Re: ts 64 pickup time?
The ts64 is connected to pin 3 of the audio squelch card's connector that drives is the high side of the volume and squelch pots. The discriminator feeds an emitter follower whose output is connected to pin 3 by a .22 ufd cap. Looks like there shouldn't be any DC there, but I'll double check with a scope. Thanks for the tip, I never thought about that possibility. 73's Skip WB6YMH --- In Repeater-Builder@yahoogroups.com, Eric Lemmon [EMAIL PROTECTED] wrote: Skip, Check to be certain that your discriminator audio tapoff point does not have a DC level superimposed on the signal. Even if the audio level is okay, the DC mixed with the signal can cause charging delays in coupling capacitors, possibly biasing off an amplifier for a short interval. 73, Eric Lemmon WB6FLY wb6ymh wrote: I've recently added a ts64 to a 2 meter Micor repeater and have noticed that the PL decode time is noticeable, probably between 1/4 and 1/2 second.

If the TS-64 is slow to open ( 250mS), either you have it tapped wrong (which is nearly impossible on a Micor), the encode tone is poor, or the decoder is malfunctioning. The problem occurs with all users so I doubt it's an encoder issue. The tone is 100.0 hz. I've never had a PL decoder on this particular box before, it use to be a packet repeater. Steve Grantham wrote: I don't know very much about the Micor stuff. Used to work on the occasional Micor unit on the bench in the GE shop some 25 years ago.. I like to use the other stuff.. Anyway.. Did you change to a lower frequency PL tone? Remember, it takes longer for the decoder to recognize the longer sine-wave. Frequency time.. If you want faster, try a higher frequency tone. (Seems like 203.5 Hz is about three times 67 Hz, and it should decode in about a third of the time.) 73, Steve AA5SG - Original Message - From: wb6ymh [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Wednesday, September 08, 2004 9:18 AM Subject: [Repeater-Builder] ts 64 pickup time?
