[Repeater-Builder] SS-32/5K/Micor
I am installing a Comm Spec SS-32 encoder in a Micor repeater. I am using a logic output from an S-Com 5K controller to key the ground connection to the encoder whenever the RX COR is active. I need to do this to be able to link into another system. My problem is when ever the encoder is keyed or unkeyed, it causes the TX to drift off frequency about +/- 900Hz. It apears that this is being casued by a cap charging/discharging. I have tried several different tone insertion points, always with the same result. Has anyone else had this problem? Is there an alternate way to hook up the PL encoder? TIA and 73, Kevin, K9HX Yahoo!

Actually there is enough tuning to allow you to use their 450-470 units from about 440 to 480so it will work for you.

[Repeater-Builder] UHF GE Mastr II /or transmission line wanted
Hi, I'm looking for a UHF repeater system. I need 7/8 hardline (about 250') as well as the station equipment. My ideal system would be a GE Mastr II base station setup, complete with duplexers. I'm interested in 75w or 110w PA, but would be willing to buy a system minus PA. I will handle conversion and re-crystaling. Also, I would be interested in buying duplexers separate if anyone has a good deal. I live in Nebraska and am willing to drive regionally for pick-up. If anyone has these items, please let me know.

TIA and 73, Kevin, K9HX You're right about the cap part, but it's an indication of a bad cap. If you have another channel element, try putting it in and see if the problem is still there. If not, change the xtal over to that element. If it is still there, it could either be both elements are bad, or more likely one of the caps in the exciter itself are bad. If you're injecting tone where the PL encoder normally injects it, then you're in the right place-don't change it. Although you COULD try putting a resistor in series with the output of the decoder.

If the R100 IS PL, then it can only do PL. DPL requires a different microprocessor and a lot of parts changes. They will go to 440 and to 474 with some alignment. They are NOT broadband. Being that the German Maxtrac, alias R100, are up near 14 to 18 years old you may need to replace a few caps, the two big ones in the power supply, and a few on the big logic board.

Software can be found at the hackersrussia web site The software hack to make the R100 go out of band can be found at: http://www.batlabs.com/r100.html The programming cable is VERY SIMPLE, and DOES NOT need a RIB interface, it just plugs directly into the serial port on the computer. That schematic is at: http://www.batlabs.com/images/r100.gif As for using the repeater - I left the R100 controller connected - somewhat, but connected the audio path cables to the empty DB-25 port on the bottom of the case as well as bringing the COR, PTT etc, all the necessary signals down to the DB-25 port. If you have a DB-25 already there, Get rid of it, its not of any use its some funky phone patch thingie, and install your own DB-25. Then make up your cable that goes from the DB-25 on the R100 to your controller. Much much more reliable, better audio, more options and control but the best thing, you will then have an IDer. The stock R100 does not have an IDer built in the controller board. One of those Motorola - DUH - things I guess. As for a manual - No can do here. I sold the last manual a while back, but you can find them at hamfests. And forget about taking it to a Moto dealer, a few years ago I had an R100 that stumped me for at least a month with a problem that disapeared if you had your eyes looking at it - but would re-aprear if if you looked away.

[Repeater-Builder] M2 station PA output network revisited
A few months back there was some discussion about the tunable antenna matching network in Mastr II station PA's. I thought I'd throw out some measurements I made today on a 100 watt UHF, 450-470 split (unmodified) operating at 442.550. With the antenna network tuned per the GE instructions, current draw was 29.0A at 13.80V (13.80V measured at the ring lugs at the end of the power cables). This equates to an efficiency of 24.99% - 300 watts of heat. The relative reading on the DVM at the test point on the antenna network was 0.92V. With the antenna network re-tuned for best efficiency (which is how I always tune them), current draw was reduced to 22.6A for 100 watts. This is an efficiency of 31.6%, 216 watts dissipation. With the network tuned like this, the relative reading at the test point was 2.82V. Note that the current draws cited above were for the whole station, not just the PA, so in reality, the efficiency of the PA by itself is a little better (and the dissipation a little lower) than what was stated above. I'm guessing the station sans PA consumes maybe 10-15W, the rest is the PA. --- Jeff Yahoo!

[Repeater-Builder] Simulcast
Hi Gang I have an interesting problem that has come to me. A small Fire Dept. near me call today and were wondering if I could get them a Zetron Simplexer. Not too familiar with it I surmised it was a digital recorder with a re-broadcaster. I could be way off in this guess. Anyway their main problem is that their main repeater located many miles north of downtown is connected via land line from their dispatch center that is located in the downtown core. When they activate the pagers the transmitted signal of course comes from the repeater, the coverage into south parts of the town is very poor in some areas so as a result some peoples pagers never active. My question is this, could a low power transmitter be located at their dispatch center that would be only keyed when a page out was initiated? This would hopefully help coverage into the lower parts of town. Hope this makes sense to everyone. Looking forward to any comments. Randy Elliott Randy Elliott R.E. Communications 234 Rands Rd.

Re: [Repeater-Builder] Simulcast
Hi Randy We used a Zetron model 55 which is a regenerative paging store and forward(imagine a digital parrot repeater.We used it for remote paging zoning but am quite sure it can be used on same frequency as voice . They were reliable and one model 55 Zetronwith a gm300\or m120 was the complete hardware required. I do remember a model 66 which could basically do voice and paging as a remote panel.

[Repeater-Builder] Re: Simulcast
Two or three ways to go: If the repeater has a high stability tx channel element, you could add a southern similcast transmitter with audio delay line and it's respective high stab osc. The process requires a bit of enginnering and setup. The other thought would be to simply duplicate the page on the added local southern transmitter, delayed or same time with an expected not-so-good sounding overlap. If the page function is not that busy, the delayed/stored and forward /que'd method would be easier and mo'cheaper. cheers skipp Randy Elliott [EMAIL PROTECTED] wrote: Hi Gang I have an interesting problem that has come to me.
