[Repeater-Builder] Deviation Limiting/Linearity
Actually, I have two problems so it might take two threads. (Long-winded too...no less) Repeater: MSR2000 Controller: CAT250 interfaced via Squelch Gate card. I have been chasing my tail on two issues. One is deviation limiting and the other is deviation linearity. It seems that if the deviation is not linear when setting up IDC/Repeater Leveland the deviation limiting in the receiver, if has an adverse effect on the DTMF decoding in the VA3TO interface that I use on Echolink. IRLP and WIRES decoders work nearly flawlessly with the same audio. I found that the 147 side of the keyboard would not perform well for a lot of DTMF sources if the deviation didn't track pretty closely from 0 to 3 K or so. We check it by putting in a 1K tone @ 1K deviation, 2K deviation and 3K deviation, etc. There seems to be a couple of schools of thought. One, adjust IDC/Repeater level so it tracks 1:1, e.g., 1=1, 2=2, 3=3, 4=4, etc. The other is to check the deviation with no input and adjust the deviation to compensate for noise in the exciter, e.g., 1=1.2, 2=2.2, 3=3.2, etc. We have done it both ways. It's seems pretty tough to get the linearity AND the deviation limiter in the receiver aligned so that the deviaton is linear and limited to about 5K and see a niceundistorted audio waveform. After we had done an alignment and was fairly satisfied with the results, a month or so later, we began to have what appeared to be an intermod or spur problem which would break squelch and key the repeater. We thought SURE it was a noisy rig somewhere or the TV Channel 11 spur we found a few months ago. We chased it around several days. We re-soldered suspected back planepins on the R1 Audio and though we fixed it. Then it comes back again. Changed out the R1 Audio card and it worked for a day or two, and it's back again! Thought it was the Squelch Gate card and checked every solder joint a few times. Used a scope to lookat everything. This morning at about 4 AM, I put my adjusting tool on the L201 deviation limiting adjustment in the receiver and cracked it a little CW (higherdeviationallowed)and the problem went away. I could see the audio noise waveformchange on the scope at the output of the receiver. I can easily find the ragged edge so I know it's this adjustment. I even put the suspected R1 Audio card back in and it works good. However, 147 won't work on K7IOUs Kenwood (again) nowbecause the deviation is no longer linear. By the way, the repeater still sounds great even if the deviaton is not linear...so long as the limiter is working. Canany of you "gurus" with lots of experience give me a hint on the alignment?Or should I throw away the VA3TO interface? Skipp, I have read your alignment procedure a hundred times, and it makes sense on paper, but I'm not confident that I'm doing it right. I would think that the deviation limiting would not have an effect on the linearity, but it seems that it does. de WD7F John in Tucson Yahoo!

Re: [Repeater-Builder] Re: Deviation Limiting/Linearity
Well hell, I accidently sent the previous before I was finished: As I was saying, when I said: I could see the audio noise waveform change on the scope at the output of the receiver. I can easily find the ragged edge so I know it's this adjustment. And you said: No, it's not... I have to ask: Then what is causing the squelch to break and why did it quit acting up when I tweaked it just a bit? It's obvisouly not aligned properly. I can turn it a tad CCW until the noise increases (possibly going into oscillation?) and breaks the squelch and then turn it back a hair CW until it stops. I can see the audio noise change when I hit the spot where it goes haywire. I have listened to this repeater for a few months with my trusty HTX-202 so I earballed it and left it until we can get to it. We will do the alignment again according to the manual soon. And you said: As I describe in my text, above 3.5KHz (service monitor) deviated test input, the MSR2000 receiver filters start to distort the audio. You can see it with a scope at the discriminator output. I say: Yep, you're perzactly right. However, on our second attemp to set the deviation back in March, we did have it looking pretty good up to 5K looking at the audio at the input of the controller. And it tracked pretty good up to about 3.5K. It held still for a couple months and then we had the Channel 11 spur that drove us crazy. It was so strong, I thought the repeater was broken. One day, there was noise getting through with the antenna disconnected.. During that episode we tweaked it again and probably messed it up. Final comment: Walt, WA4LDS and an engineer at Channel 4 here in Tucson noticed that when the picture changed on our local Fox channel, the repeater noise changed. He was instrumental in getting the Channel 11 engineer to tweak his transmiter and it is all better now.

(Long-winded too...no less) It seems that if the deviation is not linear when setting up IDC/Repeater Level and the deviation limiting in the receiver. For the non Motorhead (Motorola) people, IDC is the channel element contained deviation control. The repeater in-out deviation will never be (track) linear on any repeater ever. There are at least three wild cards in your problem list. The first is the receiver bandwidth and any included (if used) de-emphasis circuit. The other wild cards are the transmitter (both the users radio and the repeater transmitter) pre-emphasis circuits. When these values get really wacked out, we run into an unbalanced tone level (dtmf is made from two tones) called twist. A big abuser is excessive or user radio over deviation. Most people don't realize how little audio is actually required for proper dtmf and sub-tone (PL) decoding. There are standards, but most out of the box user radios are set excessively hot. Specific to your MSR-2000 and Cat Controller. Know the receiver IF filters are tight. You will not get a good detected waveform with any voice audio deviated signal above 4KHz (without sub tone). So don't try... The statement just above is much of your problem. You also didn't say how you set the receiver on frequency. John, Again set the repeater up as described in my MSR2000 to external controller text, easily found at http://www.radiowrench.com/sonic Then follow what I write below (after a few more comments). it has an adverse effect on the DTMF decoding in the VA3TO interface that I use on Echolink. IRLP and WIRES decoders work nearly flawlessly with the same audio. This might tell you about a level and twist problem with at the dtmf decoders. A scope at the controller dtmf decoder chip input will give you the real answer. I found that the 147 side of the keyboard would not perform well for a lot of DTMF sources if the deviation didn't track pretty closely from 0 to 3 K or so.

Everyone setting up a receiver should know how that receiver preforms at X value input deviation. Your target value 1:1 deviation ratio for the the MSR is about 3KHz (set at one

Re: [Repeater-Builder] Patch lead lengh between cavities ?
We used 1/4 and made sure to include velocity factor of the coax. Don't know the technical term for the type of cans, but the passband was set with the cavity and the notch was set with the probe. We used a vector volt meter to get them pretty darned close, a set for the transmit and a set for the receive. All of the probes came in except a couple had to be shortened. The commercial jumpers that were used when the bongos were converted to ham band were too short for our 146.34/.94, but they had been tuned originally as far as I know. When we built a new set of jumpers, we had to retune all six. de WD7F John in Tucson - Original Message - From: Eric Lemmon [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Tuesday, August 17, 2004 6:08 PM Subject: Re: [Repeater-Builder] Patch lead lengh between cavities ? Dave, There is no pat answer to your question, because the optimum length of the jumpers depends not just upon the operating frequencies or the design of the cavities, but also upon the physical length of the loops or probes within the cavities. The optimum jumper lengths are not the same for loops as for probes. Therefore, duplexers of identical design, but from different manufacturers, may require different jumper lengths to achieve optimum performance. It's always best to ask the manufacturer what lengths are correct for the given frequencies. 73, Eric Lemmon WB6FLY dave_g7uzn wrote: Hi Group, I know this question has probably been asked before, but should the patch leads connecting cavity filters be 1/4 or 1/2 wave in length please?

Re: [Repeater-Builder] Re: Astron Supply Help
As a troubleshooting technique, you can plug in one pass transistor at a time and the power supply will work so that you can measure voltage on the output. I have had strange things happen to an Astron 35 which has included a single pass transistor shorting out, a resistor in the reference voltage divider increasing it's resistance and causing the voltage to drop to about 8V max. Good luck. I've got one that took a power surge last spring during a lightning storm and I haven't found the problem yet.

Re: [Repeater-Builder] TLD5322 Exciter is on all the time, is there another way
That's interesting to know Mathew. We're in the process of putting a converted hi band VHF Micor on 220 and as it is set up now, the exciter is keyed. I would guess that it wouldn't be much of a delay anyway. The final stage of the exciter is keyed with keyed A- and I believe the xtal module is keyed ( I think, but I don't remember) as well. If I had that problem, I would hook up the key line again. In the bench test configuration, I do know that with the final stage unkeyed and the xtal module oscillating, we have about 7 mW at the output of the exciter.

Re: [Repeater-Builder] Re: DR-235 for repeater
David, what do you mean by: On a one-way setup, you definitely get discriminator output. When coupled to the second rig, the conditioning takes place.? Which output are you talking about?

However, I found that the treatment after the discriminator on the respective radios applied the conditioning to make the interface transparent to the ear. We have tested in-band range extenders using antenna separation to extend the range of simplex communications by using a pair of 2 meter rigs connected data port to data port. I have also done similar experiments going from 6M SSB to 2m Simplex and back. The audio quality does not have the thin quality you would expect; reinforcing the concept that the radio does the conditioning after the discriminator to the user interface (speaker and audio controls on the receiver). It took me a long time to finally accept that this was the case before even trying to use the data ports for user audio. On a one-way setup, you definitely get discriminator output.

Re: [Repeater-Builder] Re: TKR-820 PL Control
Yeah...I may use a relay. The TX PL EN wasn't the thing I needed. However, the green wire was it. (Thanks Juan) I figure it's not a big deal to short it out because it's the wiper of a 47K pot, not the direct output of an amp. I tried it this evening and it works. The signal level was about 170 mV nominal. Now, I have to switch it with COR which is available in that module too. So, I'm thinking I'll use a reed relay to do the job. It should be quick enough. What's good about it is the regular PL works as advertised while DPL can be switched on with COR. So the plan is to link with DPL and let the repeater do it's regular thing with PL.

Re: [Repeater-Builder] TKR-820 PL Control
Mark (or anyone on the list), is there a Kenwood manual that explains events in the repeater concerned with muting, PL DPL, etc.? I have successfully controled DPL (Tone) on the transmitter to facilitate linking using digital PL so that there's not tone transmitted unless there is a valid received signal. It appears to be pretty clean, but one of the locals that uses Motorola radios says something about the 46 Hz is missingstands to reason since I kill the tone as soon as the COS is dropped. I undestand that during a normal transmitter unkey, there is reverse burst or 46 Hz transmission or something like that to squelch compatible receivers. Sure would like a clear explanation of that. If I knew what I was looking for I might figure out how the signaling unit functions in that respect and come up with a method to make a clean Motorola squelch sequence contolled by COS.

Thanks Eric. At least I understand the basics now. John in Tucson - Original Message - From: Eric Lemmon [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Saturday, October 28, 2006 7:52 AM Subject: RE: [Repeater-Builder] TKR-820 PL Control John, Reverse burst is used only in CTCSS, AKA PL tone. When digital subaudible coding (CDCSS, AKA DPL) is used, a 134 Hz analog tone is transmitted at the end of the message to close the squelch. In both CTCSS and CDCSS, the transmitter carrier is held on for 180 milliseconds or so after PTT is released, so that the CTCSS tone can be shifted in phase (reverse burst) or the CDCSS turnoff tone of 134 Hz can be sent. Either scheme will mute the receiver's audio while the carrier is still present, eliminating the annoying squelch crash that would otherwise occur. One possible benefit of using CDCSS on a linked repeater network, where each repeater uses a different digital code, is that the 134 Hz turnoff tone is common to all CDCSS codes, causing every linked repeater to mute at the same time rather than sequentially. The down side, of course, is that relatively few radios made for the Amateur Radio market have either CDCSS with the 134 Hz turnoff tone or CTCSS with reverse burst capability. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of WD7F - John in Tucson Sent: Saturday, October 28, 2006 7:25 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] TKR-820 PL Control Mark (or anyone on the list), is there a Kenwood manual that explains events in the repeater concerned with muting, PL DPL, etc.?

Turns out that the 22 uFD electrolytic where the 12.8 V comes into the signaling unit had failed. I took it out and the thing worked for a few seconds. I measured the resistance of the in-series 10 ohm surface mount resistor preceeding the cap and it was reading 750 ohms. I jumped it with a 10 ohm resistor and everything started working. I suppose the heat from the soldering iron may have screwed up that resistor, but it seems unlikely. Danged if I know! Ain't electronics fun?

Point of order: Depending on the make and design of your amplifier, Make sure the input to the LM-386 is not left 'floating'. Other wise the amp makes one of the nicest broad-band AM recievers you can get. A 10K pull low resistor is all it takes. Also a 470pF capacitor to ground will help in high RF enviroments.

There are at least three versions of the Mini Amplifier all being the same basic animal. One of the first versions used the lm-386 with a transistor stage in front. The diagram for the circuit was on a paper label inside the case (very nice) and it was slightly larger than the current Mini Amplifier. Working from memory I believe it doesn't need a blocking capacitor in that model. The current Shack version is part number 277-1008 although I also have a version with the 1008c suffix. Adam T.

Re: [Repeater-Builder] Re: COS output for Kenwood
Hook that signal to the base of the transistor through a 10K or so resistor. That should provide enough isolation to prevent loading of the signal. I hope it's going positive when the squelch is open so your COS will be low when active. de WD7F John in Tucson - Original Message - From: jkstrsn [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Saturday, January 20, 2007 7:40 AM Subject: [Repeater-Builder] Re: COS output for Kenwood Jim, thanks for the suggestion. Unfortunately it doesn't have a receive LED, only a bar-graph which is also used for transmitting. The optoisolator idea has merit though. I have located a point in the radio which changes voltage, but only by about 1/2 V and it is very sensitive to loading. So far I've tried one transistor but it loads it too much I guess. I'm going to try again later this morning, I either need to find a point that switches more voltage or maybe try a fet or something so as not to load the other one?

[Repeater-Builder] Another TKR-820 Question
The line-out de-emphasized audio on pin 10 of the accessory jack of the TKR-820 is switched by COR. Discriminator audio is continuous. Does any Kenwood guru know what signal is responsible for switching off the audio when COR is not active? It appears that the microprocessor on the Display Panel could via Q6 and R45, but it doesn't appear to be the case in real life. Anybody know. I'd be happy to take it off line or call you on the phone (my nickel). de WD7F John in Tucson
Re: [Repeater-Builder] Another TKR-820 Question
Well, I figured it out. I guess there's at least one guru ;-) who knows how the line-out works. Me. Man, I hate surface mount technology, especially when your only copy of the service manual is a fuzzy pdf from a scan ! Thanks to Dave's (K7IOU) younger eyes. FYI-IYGAS:I'ts good sounding audio, much better than discriminator audio which has been de-emphasized with a capacitor in the feedback of an audio amp in the controller. Kenwood says it's 600 ohms, -10dBm, -6dB/octave, 300 - 3000, however it appeared very sharp and still required a 0.0047 uf in the audio feedback. Since it used switched line-out, it caused a nice little chirp when the repeater input squelched. Discovering how to eliminate the CO switching was the secret. Plus, DTMF detection works great with this audio so it will remain in the configuration. If it's good to go by the critics, we'll put it on the mountain soon. de WD7F John in Tucson - Original Message - From: WD7F - John in Tucson [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Tuesday, March 06, 2007 6:04 PM Subject: [Repeater-Builder] Another TKR-820 Question The line-out de-emphasized audio on pin 10 of the accessory jack of the TKR-820 is switched by COR.

Re: [Repeater-Builder] ICM Crystals Off Frequency?
Doesn't the MSR-2000 use the crystal element that has an internal range adjustment? Seems to me that when we converted one about four years ago, it wouldn't warp high (maybe it was low) enough. We opened the thing up and found a trimmer in there, moved it slightly and put it back together. We were then able to get it on frequency with the external adjustment.

Re: [Repeater-Builder] Amateur-Grade Radios (Was: Fixed Audio)
You're right, at least right about one we converted to 220 a year or so ago http://home.comcast.net/~micorrepeater/ . I don't know the model number, but it's a hi-band VHF 100W continuous machine in the tall cabinet. How do you handle the IDC adjustment? We ended up having to adjust IDC for 800 - 1K PL deviation and left it there, setting the maximum deviation via the controller. I considered figuring a way to modify the PL card or the exciter so that the level could be adjusted independently of IDC.

Re: [Repeater-Builder] Re: 224 MHz PA fun and war stories
We built a PA for the high band VHF Micor using two Mitsubishi modules. We had some problems getting sufficient drive out of our exciter conversion and we wanted higher power, so we used two modules requiring 50 mW input for 35W out. Turned into a real challenge. Using an RF splitter to divide the input and a phased power combiner/bridge to sum the outputs, we manged to get a very stable and bullet proof PA that once transmitted all night due to a controller malfunction.

Re: [Repeater-Builder] Re: 224 MHz PA fun and war stories
Haven't tried it without a fan. I would guess that the giant heat sink on the original PA would probably handle the heat easily. My only concern would be the small contact area from each module; Would the heat dissipate properly? I have a PhD physicist business partner who could figure it out, but it's about as easy to add the fan. As K7IOU pointed out in the PA site, the fine print on that particular RF module says that the unit was not appropriate for repeater use due to the duty cycle. Not sure why they came to that conclusion. Of course, he read that AFTER the modules had been purchased. So, we went with them anyway.

Re: [Repeater-Builder] Coax length between added cavities
Repeating the experiment? Hmmm. We were re-cabling a set of Sinclair duplexers for a 2-meter machine and had access to a high quality vector voltmeter. It took three of us Keystone Cops over 3 hours to make a set of 1/4, 1/2 and even a couple of 1 wavelength cables. Later, we repeated the process for a 220 machine and even though we had experience, it took about the same amount of time. My point? It ain't easy ! We just weren't ready to use the time and materials to add an inch to a set of cables and then make another set of short ones. In both cases, things worked out great. Many hams who are delving in cavity alignment don't have a vector voltmeter, so we were in good shape. Plus, you have a warm fuzzy comfort factor if you know your cables are the right length when you start the job. If alignment ain't happening, you can say I know it ain't the cables!...right ! And I got some ocean front property here in western Arizona de WD7F John in Tucson So my take is that there are critical cable lengths involved for adding a pure pass cavity to a BP BR duplexer, but I would be interested to hear from anyone aboard who has the necessary hardware kicking around to repeat that experiment and either replicate or refute the results I got.

Re: [Repeater-Builder] Re: SADL or EPLRS ?
Thanks Skipp. Yes, you're right. I'm in the process of locating the guy to talk to. I had a big awakening this morning when I went to the base and tried to find the equivalent of my old job, Avionics Superentendent, and it has drastically changed since I retired in 80. However, through the Command Chief Master Sergeant, I'm on the track and, yes, I'll be nice. I started in Armament Electronics (AE) which begat Avionics Maintenance Squadron (AMS) which begat Component Repair Squadron (CRS) which has evolved into Component Maintenance Squadron (CMS). It's apparent that the military thrives on change...either that or they keep moving things so nobody can figure out what they're doing. Popcorn is what we call it, and we can see what appears to be spread spectrum pulses on the scope. A couple years ago, it would be on during the day and off at night and weekends. Now it's 24/7 and getting stronger. And, I miss-spoke, it's 420 - 450 as you said. At least you give me a little hope with your comments and if I can find that friendly someone and buy him (her) a beer, I might do some good. de WD7F John in Tucson - Original Message - From: skipp025 [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Wednesday, August 20, 2008 9:08 AM Subject: [Repeater-Builder] Re: SADL or EPLRS ? Re: SADL or EPLRS Hi John, You MIGHT be able to find the contact person for the system. Probably your first task... followed by trying to open a very, very friendly dialog with said person(s). Advise them they are able to operate their EPLRS System below 420 MHz where the interference would be less to BOTH parties. A sidebar question of user authority in the band is based on emission designators. Although the Military may be a primary user in the band, their operation as the primary user does not include the type of emissions (emission designation) output from an EPLRS system. Depending on which wind-mill you want to chase... a case can be presented where the EPLRS emissions are secondary to Amateur operation and the resultant interference is a secondary service, which you could request be relocated. The only real world fix is to find the right person(s), provide reasons why their relocation down the band would be prudent and hope like hell they are reasonable. With the proper politics information and attitude you might have some luck (like I/we did). Then along cave Pave Paws... EPLRS will sound like a popping noise in your repeater receiver. good luck s.

Re: [Repeater-Builder] Volt-Amp (Re: APC UPS Charging Power)

I started to respond to this thread earlier, but after a few minutes of organizing my thoughts, my aging pea-brain said, Forget this and go get another gin tonic ! What's another few brain cells anyway ? de WD7F John in Tucson - Original Message - From: Eric Lemmon [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Tuesday, September 16, 2008 9:59 PM Subject: RE: [Repeater-Builder] Volt-Amp (Re: APC UPS Charging Power) John, You are correct that when the power factor is 1.00, the current is in phase with the voltage, as it will be in a purely resistive circuit. In this unique case, watts equals volt-amperes. However, when the load is reactive, the current either leads or lags the applied voltage. A typical case is a lightly-loaded induction motor, which may exhibit a power factor around 0.65, which is considered to be a poor PF. Some of the current drawn by this motor is used to create torque and perform actual work, and this current is nearly in phase with the applied voltage. Some current causes heating of the copper windings and the field core, and this current is also nearly in phase with the applied voltage. Both of these currents consume true power and are measured in watts. However, a significant amount of current does nothing but magnetize the field windings during part of the AC cycle, and that reactive energy is returned to the source as the magnetic field collapses just before the field is built up with the opposite polarity during the other half of the AC cycle. There are additional reactive losses, such as eddy-current and hysteresis losses, but the magnetizing currents are lagging the applied voltage, so they are the cause of apparent power which is expressed in volt-amperes reactive, also known as VARs. As was discussed at great length in this forum several months ago, one cannot measure true power with separate voltage and current meters. That is because the readings of separate meters are not synchronized in time. Even if one uses two true RMS DVMs to measure voltage and current, one still winds up with nothing more than apparent power based upon volts times amperes, or volt-amperes. To measure true power, one must use an AC power meter that synchronously measures current and voltage throughout the entire cycle. This can be performed by a device called a four-quadrant multiplier which, as its name implies, performs the multiplication of current and voltage through 360 degrees of phase rotation. One such instrument is a VIZ Instruments WD-767 Digital Wattmeter, which sold for about $925. Another device which has become very popular with Hams is the Kill-A-Watt meter that costs about $20 from several Internet vendors. Although not as accurate as the WD-767, it does perform quite well. As I stated in an earlier post, the rotating-disk kWH meter on the typical residence measures only true power. It does this magic by combining the magnetic fields of two coils: a voltage coil that is connected in parallel with the load, and a current coil that is in series with the load. The angular displacement of these coil windings is precisely set so that only currents that are exactly in phase with the voltage result in a torque to turn the aluminum disk. A small permanent magnet is placed near the disk so that the speed of the disk is proportional to the amount of true power being consumed. Since speed is movement over time, the disk is geared to a register that accumulates the number of rotations, which represents power over time, which is energy. Thus, the meter measures kilowatthours. You pay only for the true power that you actually use; you do not pay for apparent power since volt-amperes is not true power. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of John Barrett Sent: Tuesday, September 16, 2008 9:13 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Volt-Amp (Re: APC UPS Charging Power) This doesn't mesh up with what I've learned about power factor -- the impression that I got was a perfect power factor was 1 (one) (current in phase with voltage, equipment using everything the the power company charges you for to do useful work). Anything other than PF=1 meant that the equipment was using the power less efficiently, and therefore you were paying more in KWH than the work actually performed. That description excludes the possibly that the equipment could use more power than the power company records as being delivered (heck, conservation of energy says that in any case). any load reactance (inductive or capacitive) and the very low PF numbers stated sound more like what I get off my linear power supplies

I've been off packet radio for years, but one of the experiments I always wanted to do is try and audio DSP unit to eliminate some forms of noise. Many people don't realize it, but you have discovered how destructive noise can be to a packet AFSK signal. I had a bad power line insulator/tie wire combination outside my house that completely decimated my Netrom node digipeater. The signal sounded good to the human ear, but the TNC just couldn't decode anything but a full quieting signal. 73, Joe, K1ike Christopher K.

We even bypassed the filter, turned everything off, and the noise was still present, even on battery power. SWR is fine...the station can be heard 90 miles away. Yahoo!

Trying to add the yagi to the omni using power division topside isn't going to yield easily-predictable results. You'll have all kinds of pattern interaction between the two, with new nulls falling in quasi-random areas lacking sophisticated modeling. Your best bet is to feed the yagi with an independent feedline and bring it into a dedicated receiver. Vote the two receivers, or use different PL tones (PL steering). Depending on where the yagi is mounted on the tower and its proximity to the duplexed (transmitting) antenna, you may need additional filtering on that line as well. How much more gain toward the critical station do you need over what you have now? Chances are you're only going to pick up a couple of dB's by using a yagi as compared to your existing omni assuming it's a decent antenna to start with. A 7-element yagi has somewhere around 10 dBd gain, which is probably only 4 dB or so over a good VHF omni or on par with a high-gain UHF omni (you didn't mention what band we're talking about). --- Jeff WN3A -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Scott Sent: Wednesday, June 24, 2009 2:08 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Dual Receive Antennas OK, I can't get this straight as to how to do it... one repeater, with duplexer, an omni antenna for TX and RX, and a yagi added for RX in one direction to pull in a critical station.

I appreciate the loan offer, both from you and from several others, but I think that he (or I) will want it around for making measurements in the future. I found mine at the dump. It is a 120VAC 15 Ampere, 60 cycle, 2-wire unit. I even got the box with it, and I put an AC cord and plug on the box. This evidently came off one of the old summer homes that are around the local lakes of Connecticut. Many of these summer homes were very small and sparse, no heat not running water, from the 1920's and up in time. Electricity was a luxury and they did have 15 Amp services. That's exactly what we need - a four-wire meter (120V in, neutral in, 120V out, neutral out) at anywhere from 15 to 60 amps. And I've seen one that looked like it had three wires (in out and neutral), but I never saw it in operation. Maybe a local electrician around your area may have run into something similar out where you are? This request came in saturday morning, I spent all day saturday on a deployment, and not many electricians are in their offices / shops on a sunday...

Re: [Repeater-Builder] Radio conversion to 225MHZ
We used a TU-50 splitter and two SAV-15 power modules and modified the existing driver. We ended up with about 73 watts and turned it down a bit. Also used a form of the Wilkinson combiner for the outputs. We ground and polished the existing heat sink to mount the modules on and we know it's just about bullet proof. One at least two occasions the RC-210 controller keyed it all night. No problem.

We build an IPA that supplies the required drive for the two modules, it's a one transistor buffer that puts out about 1 watt but it's output is variable from 1/2 watt to 1 watt. This drives the two modules in parallel and the output is combined with another Wilkinson. I think Scott has pictures - it was never officially written up that I'm aware of. Kevin Yahoo!
