[Repeater-Builder] Retuning a Micor Receiver from 450-470 to 440Mhz
Hi Does anyone know what is needed to move a Motorola Micor receiver from the 450-470Mhz band. To the 440 Mhz. band. It does not receive very well. 1uv at 20db should be .5uv or better.

Well I head North in Michigan up US -131 some spots are cell dead, thats where VHF repeaters and some UHF repeaters come in depends how close you are to that Canadain Cooridor that is in the Regs. I do know the Northern Boys are if a repeater isn't available, then if HF Comm or Simplex is useable then they use it, but don't mention 11M. to them some places thats a Swear Word, Banned from their List, etc.. they are 100% dyed in the wool hams.

I don't know if Telephones Unlimited still has that old VHF 152-157 in the warehouse you can call 231-796-3250 ask for Russel Sims unless Jerry recycled it, I tried to sell it at a Ham Shop back in 1995 I think leave a message in case he's out, he can be several places. Rus is not an internet person, he buys and sell phones single line to multi line and probably any computer related stuff as wire lay out, of course the Buy of the Day can be anything brass ringers true touch tone, I get most of my stuff thru him. better than Cheap made junk that 1 lightning hit or 3 goes up in smoke, don't think he has any repeater gear 4 sale, that would be George @ SKE Electronics .

Re: [Repeater-Builder] Just a couple of dB loss you say?
The Secode tone was 2805 CPS and the mechanical decoder used a pin to latch when a proper pulse count was received. A number of the RCC phone systems used that for selective calling. The MTS and later IMTS phones used the same type of mechanical decoder but used alternating mark and space tones of 600 and 1500 CPS. The Motorola IMTS logic board was a fully discreet transistor decoder that used jumper wires to program the number. They were about 14 by 20 inch PC Boards that were really densely populated. They were a bugger to fix, most shops exchanged them with Bat Parts when they failed. Now the entire decoder is the size of a postage stamp! Jack K6YC - Original Message - From: "John J.

Re: [Repeater-Builder] Just a couple of dB loss you say?
In the earlier days of all of this, frequently a rotary dial from your home telephone was used. Most of all, not only for controlling the system but making those all important (?) phone calls too. I remember in the early seventies, someone in the Southern California area somehow managed to score a bunch of Western Electric Touch-Tone key pads. The early ones were the ten button type ... later the 12 button and, occasionally, a very rare 16 button keypad showed up. They all were made by Western Electric and worked quite well as I remember. A few of the systems I was on required the 16 button keypad, so I bought one and installed it in a Radio Shack project box. The output ran to a selector switch so I could select either the UHF GE Mastr-Pro or the UHF Motorola Motrac I was using - I had both installed in a couple of my cars at the time. Both radios were four frequency, duplexed, multiple CTCSS encode and using separate antennas for transmit and receive. I had the necessary parts for making the GE Mastr-Pro into an 8 frequency radio but that wouldn't have worked with the GE Priority Search-Lock Monitor (PSLM) Control head I was using. This was in the days of cheap crystals and rather expensive, for us, radios. Electrical systems in the cars are another story ... One car had six Motorola and GE control heads from door to door, and seven or eight antennas. Another car had a 150 watt incadescent light bulb hanging from the rear view mirror ... a map reading lamp of course. If any of you wander this direction sometime, I can show you some of these fun radios. Enjoy yourself, Neil McKie - WA6KLA "John J.

[Repeater-Builder] Secode MTS Decoders - Some History
Shades of all-tube mobile radios with Dynamotors! In 1970, I had a GE Pacer under-dash 2-channel mobile radio with a Secode MTS decoder mounted on its right side, with a PTT handset on the front. My telephone number was JL-2-6759, the JL indicating which of the MTS channels I was to monitor. A Pacer was completely tubed, but it had a transistorized power supply and put out 12 watts. The Secode decoder was an electromechanical stepper switch that responded to the 600/1500 Hz tones. When a call to a mobile unit was being made, the 1500 Hz tone was changed to 600 Hz at a 10 PPS rate. Each pulse ratcheted the decoder wheel one notch, and pins were placed at each notch that represented one of the digits of the assigned phone number. If a pin was at the notch where each pulsing series ended, the wheel would be latched at that point, ready for the next digit. As each of the five digits was dialed, the wheel would make it all the way to the ringing contact. If any of the five digits did not match the pin placement, the wheel would not be latched and would return to the home position. Because there were few MTS users in town, I usually knew that an incoming call was for me, simply by counting the stepping sounds in my head. In 1970, the move to IMTS had already begun. IMTS used frequency-agile radios that could place and receive calls automatically. To place a call, I had to lift the handset and first ensure that nobody was using the channel. If it was free, I keyed the PTT for two seconds or so, and waited for the mobile operator to respond. I then gave her my mobile telephone number and the number I wanted to call. This was certainly a slow and bothersome way to make a phone call, but hey- this was in the "early days" of mobile telephone service! 73, Eric Lemmon WB6FLY Mark Holman wrote: > > This sounds like the way the old mobile Radio Telephones used I think was 20 > khz.

Re: [Repeater-Builder] Just a couple of dB loss you say?
Mark, The Public Mobile tel's used 600 / 1500 Hz alternating when a mobile was dialed. The first signal sent was a 600 followed by a 1500 Hz tone to clear the selector, then the number was dialed. This was the old YJ,YK,JK etc stations Tx on 152.xxx Mhz. The receiver in the base station was 5.26 Mhz higher in freq. Western Electric made a big beast of a decoder with an wheel in it for programming and later here in Canada we used an Electronic selector made by Scantlin Co (I used to fix those brutes back in the early 60's while working at Bell Canada.)

Re: [Repeater-Builder] Just a couple of dB loss you say?
This sounds like the way the old mobile Radio Telephones used I think was 20 khz. ( ?? ) tone and the rotary dial , and looking at the control in that fashion old RT used the 152-157 Mhz. offset I think if I have it right. Mark A.
