[Repeater-Builder] Another Voting Equipment Question.
Hello to the group. I am building a 3 channel voting system for a local repeater group and I was wondering what the rest of the world is using as a interface for the voting reciever/transmitter package. How are you configuring your pl? I have built up some MVPs and that part was a slam dunk. I have purchased an ICS Basic that I have installed in one of the MVPs but I am not getting the results I was hoping for. It does not seem to pass the pl as I thought it would. I have the de- emphasis cap pulled, and I am feeding the CG Hi line on the exciter, (don't have a cow, I am going to use a limiter before I install the package) ;-) but the audio seems to sound a bit funny, and it doesn't want to pass the pl properly as it is intermittent at best. I know that many use nothing more than an audio interface with a cos to ptt linkup but I wanted some control over these things as well as an ID'er if they are going to be 75 miles away so I opted for a controller. So, the question is, what are you folks using? What say ye? Thanks in advance. Johnab6li Yahoo!

Re: [Repeater-Builder] Another Voting Equipment Question.
Hi John, I doubt that the problem lies in the controller, but rather your 'modulator' isn't flat. If you scope the audio path, you should be able to make sure that you don't have excessive roll-off or distortion in the audio chain. My suggestion is to change the exciter to provide True FM. This can be done by adapting a Mastr II PLL ICOM and installing it into the MVP. The AP-50 is a nice solution to feeding discriminator audio to the FM ICOM. While this article isn't written around the MVP, it can be generically followed to do what I have explained: http://www.repeater-builder.com/ge/mastrII/ap-50-fm-mastr2.html If I were doing this, I would feed Vol/Sq high to the AP-50 *and* the controller, using a simple resistive splitter. Have the controller there to do all of your necessary functions for control, but not run the audio through the controller to be repeated. I would modify the controller so it couldn't pass audio, by removing the gate transistor. This will allow you to feed audio to the controller for processing of tone commands. The AP-50 would take Vol/Sq high and feed it directly to the FM ICOM. Set the AP-50 so it doesn't de-emphasize, or pre-emphasize the audio. Take the audio output of the controller and feed it to the CTCSS port of the AP-50 so the responses of the controller can be heard. This will insure that the audio is not muted and the least amount of *stuff* exists in the audio path, but still having the necessities. Kevin John Everson wrote: Hello to the group.

Re: [Repeater-Builder] Re: Sinclair Q 202G Tuning Problem
The loops can be rotated a slight amount, as they are mounted in round holes on top of the vertical cavities with the notch tuning rods extending horizontally from the loop assembly. Three screws clamp the assembly to the can. The rods would interfere with the cavity beside it if rotated more than 5 degrees or so. I suppose the internal loop could be bent or twisted to space it away from the internal quarter wave as the whole assembly lifts right out of the cavity when you remove the screws. I measured the jumper cables end to end including the connectors (10.5 inches) and also measured the two new cables I made (12.5 inches) the same way. Tinkering with the capacitance would sure be a lot more trouble than rebuilding the cables I think, so this was definitely the right way to modify the 170 meg duplexer down to 147 meg. If the whole harness assembly is still available from Sinclair then Eric (WB6FLY) had the right idea to just replace the whole thing. Just buying a couple of cables would cost $50 or so, and the whole assembly at $150 would be a bargain. 73 - Jim W5ZIT That was suppose to be 10.5 of cable before the N male connectors are put on. Adding the connectors adds more length to the assembly. Where did you measure the 10.5 of cable? Rg214/u or Rg213/u both have the same velocity factor so the lengths would be the same. Can't remember if the loops on that configuration were rotatable. Rotating the loop would change the insertion loss and the pass to reject spacing. There are several variables that effect the overall response.

What to look for to determine this? Well a big first step would be to figure out what sort of line it is. There should be a number printed on or embossed into the jacket every so often. Visual inspection for any damage to the copper jacket, kinks, water intrusion.. Hardline does not like to be bent, you need to observe a proper minimum bend radius that is specified for the type of cable. Connectors: Well, be prepared to be amazed at pricing. Ebay is a good source, but of course you need to know what sort of cable you have first. Many connectors can be re-used, but you need to carefully follow the directions to apply the connectors. It's easy to make an expensive mess by being sloppy or taking short cuts. Yahoo!

What to look for to determine this? What kind is it? It should be listed on the jacket. In general, N and PL259 connectors for most kinds of coax can be found for not a whole lot of money on Ebay. I've also found good deals at swaps. If the coax is unterminated, look into it with a flashlight. If you can see water marks on it, you probably have something which at least needs the ends chopped off to get around the water damage, to having a somewhat worthless chunk of copper. Even hard line with no obvious damage can be bad; I found that out the hard way once. Really, the best way to test it is to stuff some connectors on it and see what the loss is with a watt meter. --STeve Andre' wb8wsf en82 Yahoo!

[Repeater-Builder] Re: Sinclair Q 202G Tuning Problem
The side mounted loop stub Q202s had different loops based on frequency and spacings for a given a given isolation. Most cavities were designed for 0.6dB Insertion Loss so 4 cans produced 1.5dB or less per side. You could distort it to change the insertion loss. You can rotate the loops on the top mounted cans for both the stub and capacitor types of Q cavities to change the insertion loss and notch depth but you should have the proper test equipment to see the effects of those changes. Distorting the loop will also affect the can's insertion loss and notch depth and locations. Opening up the loop to have more area inside or rotating the loop so that it becomes more in line with the radial line out from the center gives the cavity less insertion loss but when the notch is adjusted for the desired separation, the notch depth is less and it becomes narrower. The notch might not come in close enough either. Conversely, if the loop is squished smaller or rotated away from the radial line, the insertion loss increases at the pass frequency and the notches move closer to the pass. Adjusting the notch to the desired spacing will produce a deeper wider notch than before. Doing this to a duplexer, improves the midband isolation between the TX and RX ports. Note, when a loop is rotated or distorted, the pass frequency of the cavity will move and will have to be adjusted before adjusting the notch frequency. You should not distort the loop of a loop with a capacitor since they are extremely fragile and will break if there is force applied. Also, soldering the loop on the capacitors is tricky as well and must be done quickly and so that it doesn't unsolder apart.

[Repeater-Builder] Semi-Rigid Coaxial Transmisson Line.
There is a formula in most hand books where the characteristic impedance can be determined from the inner diameter of the shield and the outer diameter of the center conductor. I have built many makeshift connectors using an UHF barrel, PL258, and slotting the outer conductor of the cable with a hacksaw, then driving the barrel over the center, applying passivating compound, and using a hose clamp to secure the shield to the barrel connector. I have used UHF barrels on 1/2 and 3/4 lines with good success. Also there is not a whole lot of difference between 50 and 75 ohm cable. Also, for a given diameter, the loss is pretty much the same with some difference due to dielectric losses. Steve -- Ham Radio Spoken Here.NU5D YAHOO!

Differant dielectrics usually let you use a larger center conductor for the same outer conductor diameter to keep the impedance. __ Do You Yahoo!? Tired of spam? Yahoo!

There is a quick fudge method to determine yes/no 50 or 75 ohm line (if the line is good). A good 50 ohm line properly terminated will have an SWR of 1.1:1 (one to one or flat). If the line is 75 ohm line, the SWR will rise to about 1.4:1 or 1.5:1 when driven with a 50 ohm source and terminated into 50 ohms. The above is only a relative check/test when the line is assumed to be good. Mini Circuits makes a bidirectional 50 to 75 xmfr, which can be used along with 75 ohm terminations to verify the 75 ohm segment. If you were using the 75 ohm line for receive only applications, you could just keep the Mini Circuits 50/75 xmfr in line. If you wanted to put rf power into the 75 ohm line, you'd need to make a matching network. Not hard really, but it's much more frequency range or band dependent.

I've done similar with a trip to the better local owned hardware store plumbing section where a number of copper pipe adapters can be used to adapt different sizes. Using a 75 ohm line on a 50 ohm system often means an instant 1.4:1 to 1.5:1 SWR. Relative to the grand scheme of things... some people can and do live it the mismatch quite well. cheers, skipp Yahoo!

[Repeater-Builder] TKB or TKR-720 on 220 Mhz band
Hi I received a new KPT-50 programmer for the Kenwood TKR-720 and 820, and TKB-720 and 820 radios. The manual for it indicates that the 720 series of radios can be programmed from 130 MHz up to 230 MHz. I wondered if anyone has programmed and retuned one of these radio to operate on the 222 MHz band? I wondered how well the receiver worked and how much RF power was output? Thanks Byron NJ7J Yahoo!

Re: [Repeater-Builder] Two bands, one antenna, many problems?
You may run into an issue of that the Local Oscillator of the UHF repeater would create interference if one of the stages in a crystal multiply up chain was the input of the VHF repeater. Look at this: 146.13 * 3 + 10.7 = 449.09. Of course the reverse is also true with the possibility of the VHF's transmitters and local oscillators 3rd harmonic jamming a UHF repeater, which happens quite often on repeaters with remote bases. 146.73 * 3 = 440.19 Yahoo!

The tk-720 probably won't operate outside the 148-165 band without mods or at least retuning to the desired section of band if it's within the limits of the radio design. We see things like the 130-230MHz range because radios were made for other countries where operation in non US standard bands are considered normal (standard) Hope you like the programmer, I have 2 more in stock and then they're gone... cheers, skipp skipp025 at yahoo.com www.radiowrench.com Hellewell, Byron [EMAIL PROTECTED] wrote: Hi I received a new KPT-50 programmer for the Kenwood TKR-720 and 820, and TKB-720 and 820 radios.

I wondered if anyone has programmed and retuned one of these radio to operate on the 222 MHz band? EEWW.. I know the 720 was made in at least two band splits, because we got the wrong one at first and it wouldn't come down into the ham band. Wether you can program it there is a very different question from wether it will operate there. Inherently broadbanded designs are inherently bad for repeater use. In our case, we were finally able to eke out 18W without the solder melting on the finals, after I replaced the regular solder with silver solder, and added small heat sink fins. The 720 we had also had a synth issue. After being in service for 3 months or so, it started hopping between our frequency and the local airport tower frequency. This happened very quickly, such that it appeared to be transmitting on both bands at once. The synth was madly signalling to the CPU that it was unlocked, and the CPU was blithely ignoring that. I'd be very surprised if there was a single 720 model that covered this spread. I'd be even more surprised if using it that way was a good idea. Yahoo!

[Repeater-Builder] Ques about hardline
David [EMAIL PROTECTED], who eschews obfuscation, said: I have some hard line I that a friend gave me and was wondering how to determine if it is any good? If you can borrow one, a Time Domain Reflectometer can't be beat. You can backtrack the impedance and velocity factor if you know the length of the cable. Vary the velocity factor until the TDR indicates the proper length. Then inspect the cable carefully from end to end and look for any impedance bumps which are reflections. The TDR will tell you the distance to the fault, and the screen or outboard scope is you use one will show you the type of fault. I used the TDR to find a bad splice on a run, and water in the hardline to antenna jumper on top of a 285 foot tower with 600 feet of feedline.

Re: [Repeater-Builder] Two bands, one antenna, many problems?
Dave, the problem with the diplexer that burned up is that its power rating was given in PEP and not CW. You need to find one rated for your total power in CW. As you know, PEP is a low duty cycle mode in SSB. I think your Comet unit was faulgty going in because it shouldn't have failed at those power levels. Have a look at the Diamnd MX72D 100 W CW UHF; 150 W CW VHF Note that its power rating is fotr CW and not PEP. 73, Dick - Original Message - From: Dave VanHorn To: Repeater-Builder@yahoogroups.com Sent: 24 April, 2006 13:32 Subject: [Repeater-Builder] Two bands, one antenna, many problems? While I wait to see if the horrible noise has been eradicated, I'd like to see thoughts on the next thing I'll be turning my attention to: I can't change my antenna, other than to replace it with an identical one. What's up there now, is similar to a Comet GP-9 dual band antenna. We're running the VHF pair now 146.85- at 30W, without any issues. We're coordinated for another pair at 441.9+ and 50W I had a comet bandsplit unit (they call them duplexers, but I'm not going to for obvious reasons) which suffered an internal meltdown at this relatively modest power level, despite a nameplate rating of 800W pep. So I'm looking for feedback on bandsplit units, and basically anything that I can do to make this work as well as possible. We are still looking for another site, but that has proven very difficult.

[Repeater-Builder] Vertex VXR-7000V
I am in need of a service manual or at the least a schematic for a VXR- 7000V repeater. Yaesu/Vertex has not been responding to requests. We purchased this repeater new and would like to put it in service. The site where the repeater will be installed is a solar powered site. The 7000 normally runs on 115 VAC. There is a hookup for an emergency battery. When the AC mains fail the repeater switches to the battery. However, the output drops to 10 watts to conserve battery power. I am hoping that this is done by reduced drive, and not a change from say a 28 VDC power supply to the external 12 Volts. If anyone knows and can help out I would appreciate it.

RE: [Repeater-Builder] Re: TKB or TKR-720 on 220 Mhz band
The one with two splits was the TK-710, the 720 can be programed to full bandwidth, only needs retuning the front end and the both VCO's.. Juan Tellez A, XE2SI EEWW.. I know the 720 was made in at least two band splits, because we got the wrong one at first and it wouldn't come down into the ham band. Wether you can program it there is a very different question from wether it will operate there. Inherently broadbanded designs are inherently bad for repeater use. In our case, we were finally able to eke out 18W without the solder melting on the finals, after I replaced the regular solder with silver solder, and added small heat sink fins. The 720 we had also had a synth issue. After being in service for 3 months or so, it started hopping between our frequency and the local airport tower frequency. This happened very quickly, such that it appeared to be transmitting on both bands at once. The synth was madly signalling to the CPU that it was unlocked, and the CPU was blithely ignoring that. I'd be very surprised if there was a single 720 model that covered this spread. I'd be even more surprised if using it that way was a good idea. Yahoo!

Re: [Repeater-Builder] A couple of questions about hard line
Correct, MF tones were used on inter office trunk circuits. These were the tones that people used to simulate to dial free toll phone calls. Each digit was made up of two tones, but not similar to the Touch Tone frequencies.

Re: [Repeater-Builder] telco and ctcss tones
As someone already pointed out, the PL tones are weird frequencies so they're not harmonically related. DTMF tones are similarly set at odd frequencies. DPL/DCS codes use only about 100 of the 512 possible codes for the same reason, so repeating bit patterns aren't falsely decoded. Paging tones are also similarly unrelated. And of course you want to avoid 50 and 60 Hz, and some common harmonics of those. Bob M. == --- DCFluX [EMAIL PROTECTED] wrote: Here is an age old question that has yet to be answered satisfactorly.

Re: [Repeater-Builder] Vertex VXR-7000V (and another question)
Don't have a book in front of me, but I am sure that unit is entirely 12 V DC inside. The change in power level is a programming issue (factory default output for low power is 10 watts, and you can change it from dealer mode in the CE27 software) NOTE - I never did check to see if the low power setting in the software really does change it for the battery mode as well. Now for my VXR7000 question ... Is there a way to turn on or off anti-kerchunk. I have two units in service, both narrow band with DPL access. One of these units comes up right away (ie, no delay in tx from a received signal), and the other unit has more than 1.5 seconds that it seems to delay before it will turn on the transmit after receiving a valid signal.

I can send you the parts LIST that you need to change in the TKR- 720S VCOs (Both TX and RX) to make it a K2 if you would like. That is what I have done with both of mine here and they work GREAT!! Thanks, but no. That's over and done with. Although the receiver was pretty good, the transmitter rather sucked, and it's the best kind of problem now (someone else's!) Yahoo!

It may be that there simply is no easy integer relationship. I've toyed around with the idea of doing a PL encoder/decoder in software, but hadn't gotten around to it yet.

I haven't found any simple relationships between the tones. More trivia, Actually, adjacent CTCSS tones are approximately 103.5 % apart, so that they have no harmonic or simple integer relationship. Any closer in frequency would increase the likelihood of falsing by adjacent tones and any further would waste spectrum. The tones were picked back when the encoders and decoders used mechanically vibrating devices similar to tuning forks to select the proper tone frequency. The Q of the mechanical devices then and the manufacturing tolerances dictated this spacing. This was state of the art in the late 1950's and the tones were probably picked by Mother Motorola although GE, RCA and the others soon followed. Multiply a tone by 1.035 to get the next higher tone and divide by 1.035 to get the next lower tone. This usually comes close. They are rounded off to a tenth of a cycle. The use of CTCSS signaling was touted to allow up to ten times the number of users on a channel as compared to using simple carrier squelch. 73, Al, K9SI Yahoo!

RE: [Repeater-Builder] Re: TKB or TKR-720 on 220 Mhz band
I did not say TKR-720 repeater, I said TK-720 mobile radio or the TKB-720 base radio... -Mensaje original- Juan, I hate to say it but on this one you are wrong. The TKR-720 was build with two different splits. The K (or K1) split ran from 150.00 MHz to 174.00 MHz and the K2 split ran from 136.00 MHz to 150.00 MHz. Dave, I can send you the parts that you need to change in the TKR-720S VCOs (Both TX and RX) to make it a K2 if you would like.

Juan Tellez A, XE2SI EEWW.. I know the 720 was made in at least two band splits, because we got the wrong one at first and it wouldn't come down into the ham band. Wether you can program it there is a very different question from wether it will operate there. Inherently broadbanded designs are inherently bad for repeater use. In our case, we were finally able to eke out 18W without the solder melting on the finals, after I replaced the regular solder with silver solder, and added small heat sink fins. The 720 we had also had a synth issue. After being in service for 3 months or so, it started hopping between our frequency and the local airport tower frequency. This happened very quickly, such that it appeared to be transmitting on both bands at once. The synth was madly signalling to the CPU that it was unlocked, and the CPU was blithely ignoring that. I'd be very surprised if there was a single 720 model that covered this spread. I'd be even more surprised if using it that way was a good idea. Yahoo!
