SNIP Expected receiver sensitivity is 0.7 uv SNIP That's what the manual says ... ;) I sold my last Mark XII/T44MSN/T1411/etc at the Rickreal ham swap meet several years ago. I had a lot of trouble getting the receivers to meet spec, usually had to settle for about 1.0 uV. That was typical of receivers in mobile telephone service, which usually were listening to very strong (possibly simulcast) transmitters. In typical land mobile, such receiver sensitivity was usually unacceptable in a quality system. True ... I think, in that era of equipment, a person who wanted to be duplex would have been FAR better off to use a Motrac or Mastr Pro modify it for full duplex operation with seperate antennas. (Which is what you did, Neil - I saw both your radios!) Although those radios are now out of service, I still have them. One is a GE Mastr Pro with four freq and duplexed ... the other is a UHF Motrac U64MHT - also four freq and duplexed. The other problem with those radios, was the transmit PA. It was a MSN 45 watt 150 MHz transmitter Actually a 30 watt tranmsmitter - I used to service them ... with a varacter tripler on the final output. Yup. Sometimes a real squirrel to tune ... but that was part of the fun. Not very efficient slightly tricky to tune!! Also, the tuning of the varactor was (of course) a capacitor a metalic tuning tool was basically needed for the necessary strength required to turn that capacitor. If you happen to accidentially short across the capacitor plates with your tuning tool, you would blow the varactor diode. Sounds like you had the wrong Motorola tuning tool ... :( Last time I checked probably 10 years ago, the cost of that diode was about $145 dollars using my discounted pricing at Motorola Rather than buy a new diode, I waited until the next Dayton Hamvention where I bought a whole identical radio for about $10 or $20. That night K7LJ I pulled out the varactor stage trashed the rest of the radio. Trashed the rest of the radio - that's too bad ... The only other thing good in those readios was that they had a tunable harmonic filter which worked well for using as a front end filter on frequency agile radios. Example: a 440 MHz remote base to cover a 10 MHz operating range but filter out signals on other bands or more than 20 Mhz away. Yup ... Neil - WA6KLA Yahoo!

Re: [Repeater-Builder] TS-64
This is defeatable, I have described this several times - instead of turning off the tone generator thereby activating the reverse burst just use a hold low in between 2 15K resistors to pinch the pl output of the ts64 module going towards the modulator. To use this you will have to hold the orange wire low full time, and you will find the switching time is faster than the reverse burst. [EMAIL PROTECTED] wrote: Hi Guys, We've discovered something interesting about the TS-64 CTCSS module. The encoder portion has a built-in reverse burst feature which is not defeatable. Problem is, the reverse burst lasts about 150 mS, which is long enough for the decoder on the other end to start decoding again. This caused some interesting problems for one of our customers with a linking system. Apparently, the reed decoders do real well with reverse burst times of 150-160 mS, but that's too long for solid-state decoders.

[Repeater-Builder] Reverse Burst
Comm Spec or Selectone used to make a simple (and cheap) reverse burst board that worked well. PC board about the size of a postage stamp square. My last conversation with with the factory said they didn't make enough money on them to keep production going, but they were able to supply me with diagram for the RB-1 I obtained second hand. Might be time to dig that diagram out and make it available. cheers skipp025 at yahoo.com Yahoo!

Re: [Re: [Repeater-Builder] TS-64]
It's not that hard... Unfortunately I don't have a working test bench right now to do any engineering. If somebody wants to run with the idea below and do the breadboarding and write up the article I'd be glad to edit it, HTML-it, and post it. Basically you leave the encoder running all the time (Virden, it that what the orange wire you were referring to does?), and have two resistors in series between the encoder output and the TX modulator input. A FET goes from the center point to ground. You control the FET with the RX COR so that the encoder audio is pinched off when the RX squelch is closed. You can also use an ordinary NPN transistor in a pinch. You'll need Courier font for the diagram below. encoder output --\/\/\/--+---\/\/\/\/ to TX modulator (usually ! the top of the dev pot (may ! need a DC blocking capacitor) ! +--! !---\/\/\/---to controller output +--! or COR output ! gnd Personally, I'd not use the raw COR output - I'd add a little delay somewhere in the system so that a fluttery signal didn't flutter the PL encoder on and off Maybe use and RC network, or set up a logic output on the repeater controller with a 1/3 to 1/2 second delay and control the FET with it, and have a 2 to 3 second carrier delay (hang-in) timer on the repeater. End of problem. By the way, this trick has been around for 30 or so years - I first did it on WA6EWS's Mocom 35 to allow the PL encoder to be enabled or disabled - Moto had a T-filter using two resistors like the diagram above with a capacitor to ground... I used the front panel extender switch to short out the cap and disable the tone.

Yes, it can be done as long as the frequencies are far enough apart. We used some TX/RX duplexers to put two 2 watt security transmitters on the two frequencies of a repeater pair into the same 450 antenna. This was done to send local alarms from a store and forward repeater site where the second frequency wasn't used so we didn't have to install a second antenna. Art - KC7GF Yahoo!
