[Repeater-Builder] Unidentified part in msf5000 vhf station
I just aquired a second msf5000 to make a 2 meter repeater our of and it has a part not present in the first station. I suspect it could be a rx preamp due to the fact it has coax input and output and it is wired in series between the duplexer rx port and the receiver rf input. It appears to be an aluminum block rack mounted just below the power supply and is about 1.5 thick and about 8 or 9 inches wide. I did not see any electrical connections so if it is a preamp it must get power from the coax into the receiver. I am not familiar with this device. My other station did not have this part. Perhapps it is sopme kind of filter? Both stations are the digital capable models which I program with the rib and old laptop. Any ideas please! Pictures on request if needed.

I'm thinking of using one bp/br can that will have the notch wide enough to cover both channels and one pass can on our RX freq. I can also add more pass cans or something like the DCI window filter. The real question is where to these can go and in what order. We have a standard Q-202 duplexer that worked fine before the pager was put in. I'm thinking that the pager cans will go on the RX side of the duplexer, but does it matter if the pass goes on the duplexer side or the RX side of the bp/br can?

They are heterodyne receivers after all. I'm considering an ICE broadcast high-pass filter that cuts off at 1.8Mhz (model 402). I have an email into them to see how well it might work at 448 Mhz.

In doing some more research, I found a 1250kHz AM station within a mile or two that changes pattern between day and night. The interference mentioned above would appear around drive times (like 5pm) so that had me chasing other sources. Still, it was puzzling that a 5Mhz signal could be causing the feedback (it didn't appear when doing normal receiver testing with a service monitor). The recent give away was that I could hear talking underneath my test signal (like a sports show). So, if we take the 1250Khz signal or 1.25Mhz x 4 = 5Mhz. I realize that the 4th harmonic of a 5KW broadcast station isn't very powerful, but being in its nearfield might be enough to cause a mix with the UHF transmit output. Does this make sense? This phenomenon can be duplicated with both a 450 and 440 repeater system - both with standard 5Mhz offsets. I don't think any sort of filtering would work since the mix happens in the air. Only by having split PL's can the lockup be prevented, and equipment was both MSF5000 and Micor systems, through correctly tuned duplexers. Thanks, Tony Yahoo! Groups Links Yahoo!

Repeater, we are using a TRAM 1481 Dual Band Antenna on. This is the high gain 8.3 dB VHF/11.7 UHF. The system uses UHF Repeater, VHF Simplex, and IRLP. The antenna works very poorly on UHF and much better on VHF. The SWR is about 3-1 on both frequencies. The antenna is not DC Ground and there is no shorted connectors. Lack of help prevented us from taking the antenna down and apart at this time. We ran tests by putting the antenna on a portable and working a fixed base and again the VHF pinned the meter and the UHF was weak, only a couple of S units better than the portable rubber duck. Has anyone had a similar problem. I understand that the antenna is a compromise and not as good as a single band folded dipole for example, but several of us have these and they work great except for this one. I am thinking there are enough Tram 1481 out there and someone may have had the same problem. I can't speak for the 1481 since I never had one, but I never had any matching or duplexing problems with the 1480 (lower gain 8' version). I also have a few Comet GP9s in service they work fine, with advertised gain on both bands - no compromise. Also there has been many posts about the LMR400 used in repeater service. It is my understanding that the foil type should NEVER be used between duplexers, from the TX, RX to the Duplexers, but I am not sure about between the duplexer and the antenna. Comments please! You definitely don't want LMR400 any place where duplexed signals are present. This means between the duplexer antenna. Not sure why it would be a problem for the TX RX connections to the duplexer unless the connectors weren't installed properly, but then again why take the chance on a short jumper where loss isn't an issue?

Apologies if this has been answered before, i searched but couldn't find anything specific. Any info gratefully received, Cheers, Where is around here ? From what you are saying it sounds like whomever set up the repeater(s) does not understand de-emphasis and pre-emphasis. From the article at http://www.repeater-builder.com/tech-info/flataudio.html ... Another problem that rears its ugly head unless you know the equipment you are working on intimately... If you pick off raw (i.e. not de-emphasized) audio from the receiver discriminator and pipe it into the microphone jack of a transmitter you will end up with an extra level of pre-emphasis (commonly called double pre-emphasis) that will cause the audio to sound very tinny or shrill (take your home hi-fi, tune to a talk radio station, center the bass and the treble controls, note the audio characteristics, then crank the bass control to minimum and the treble to maximum - and mentally double or triple the overall effect). On a true FM transmitter you can sometimes bypass the pre-emphasis network, on a phase modulated transmitter there is no way around it without adding a de-emphasis network in front of it to compensate. This is why many repeater controllers have a built in de-emphasis network that can be jumpered into the circuit or jumpered out as needed. Likewise, picking audio from the receiver after the de-emphasis network (in some receivers that point is after the volume control and the audio muting part of the squelch circuit) and piping it into a true FM transmitter modulator can produce audio with extra amount of de-emphasis (commonly called double de-emphasis) resulting in a very muffled, bassy sound with no high frequencies (same example as above, but crank the bass control to maximum and the treble to minimum - and mentally double or triple the overall effect). Either of the above two situations is instantly recognizable by an experienced ear. Mike WA6ILQ
Re: [Repeater-Builder] DB-224 patterns on side of tower.
Done this several times. The tower will cause a shadow on bhe back side no matter how you position the dipoles. If you are wanting maximum gain in one direction away from the tower you must like up the dipoles in that direction. Moving some to the side really wont help the sides enough to tell and it will reduce the gain in the desired direction. I believe the DB products engineers know what they are talking about. For example if all dipoles are away from the tower leg in line you might get 9 db in front, 6 db to the sides and very little to the back. If you turn dipoles to each side you still get about 6 db on each side but now only 6 to the front. Dipoles are not very directional and when all are in phase together you get maximum gain in that direction. You will never get an omnidirectional pattern on a side mount nd if you need the offset patern to shift the signal in 1 major direction follow the manual directions. I have an 8 bay on the side of a tower with 36 leg spacing and it is located 16 miles away from the center of the desired coverage area. At 450' above ground it gives aprox 60 mobile miles to the front, 45 miles at 90 degrees and 25 to the rear on the 2 meter band. WB5OXQ.

However, one of the old salts here (who has final say-so) says that you really have to put some left and right angulation on the elements to get that pattern.

While not a true repeater, I hoping the gurus here can help me. Station info can be seen here; http://www.n8wct.com/n8wct-4/ The noise is a subtle low-frequency bacon crackling. It is apparent across the whole 2 meter band. Every piece of (my) equipment has been replaced, or substituted. 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. Even though the noise is subtle, the pops seem to be on frequency with the packet tones, thus, the radio requires an S8 strong receive signal, before the TNC can decode it!

Re: [Repeater-Builder] Re: Are you ready for narrowbanding?
I purchased a used MSF 5000 UHF repeater from a Motorola shop and they installed the narrow band filters and set it up for a nb commercial channel for me and it works great. It does not deviate past 2.5, receives well and the ctcss noise is not noticeable on the stations. Having programmed another vhf MSF 5000 for 2 meters, I know the ctcss level is not separately adjustable. Apparently these stations work well modded for bum wb5oxq.
Re: [Repeater-Builder] Six Meter Repeater Noise Issues
I had a problem like this but it was all the time and it was caused by a faulty matv amplifier in a apartment building a block away from the repeater. It cause the rooftop TV antenna connected to the matv amp to radiate. A now retired and possibly deceased FCC examiner out of the Dallas field office made a trip to our town at the request of our ham club and he tracked the problem down and made the owner of the matv system shut their equipment down until it could be repaired A low band TV antenna amp going into oscillation can cause a lot of problems on 6 meters. BTW a first phone tech who installed the matv unit argued with the FCC inspector and got his license revoked in the process.

Re: [Repeater-Builder] Kenwood squelch quality
Guys I was not trying to stir up discontent. I got my ticket in 1974 when very few if any ham repeaters had ctcss. It was a lot of fun and when the band opened you could work dx on your local repeater. I really liked that. Now, however, in Central Texas at least, there is so much congestion that you have to run ctcss or have your repeater become almost unusable much of the time. Then the coordinators got really insistent on ctcss so I got on the wagon. At one time I had 5 repeaters on the air in this area that I had built for various hams and we put ctcss on all of them. We mostly all use 123.0 in this county so everyone here knows which tone to program into their radios. We are too close to Dallas and FtWorth not to use tone to stay out of each others hair. There are few pairs left around here to put a repeater on 2 meters. I loved the 70s but it is over for many of us. If you are in a remote area with a good antenna site carrier squelch could be fun! Thank goodness I only have 1 repeater (on ham bands) to maintain now. I spend much of my time on 75 meters AM and many don't like that mode either!

[Repeater-Builder] MSR 2000 alignment problem
I have a uhf msr2000 which I recently changed frequency to 464.075/469.075. Original freq was about 1.5mhz away. I sent the elements in and had them recrystaled. After I installed them and tuned up the receiver it worked pretty well for a month. I noticed it loosing sensitivity lately so I got out the service monitor to check sensitivity. Here is the problem. If you tune the frequency trimmer for best quieting you get very scratchy audio. If you tune for best audio you loose sensitivity. I did not bother the discriminator coil but if it is misaligned will that be my problem? If aligned for best quieting it breaks squelch at around .21uv but at best audio recovery it only makes .8uv. This is with the generator passing through the duplexer with the transmitter disabled. The duplexer is factory Motorola.

Re: Re: [Repeater-Builder] More on Copper theft
A local AM station here in Waco recently had much of its rack mounted equipment stolen during the daytime and it was not noticed until that night when the site which was only on the air after sunset would not come on line. Thieves got away with this since many tower sites are located in cow pastures with nobody around to see what is going on (except the cows). I have since installed alarm systems on the buildings with wireless cellular backups in case thieves cut the phone line to the transmitter site. Too bad thieves did not try to touch the tower when it was energized. 10kw of rf can burn you pretty bad and I doubt the transmitter would shut down quickly from only a human body shunting it to ground.
