If it is like most resent Motorola radios, It takes Software,
RSS, and Programming Cables. We do not have these in our shop, but have MCS2000, Spectra's, SABER's, MTS2000, and many more. All Require RSS Software and RSS. Good luck and mayby someone else can give you a better answer. * REPLY SEPARATOR * On 3/27/99 at 9:49 PM D.J.H. wrote: From: "D.J.H." <ve6zh@...>several,would like to find out how it is done.-------- New hobbies?

reliable. The eprom just seems to go south after a few months and would have to send $40 for a new one. First it would go buggy decoding my tones, then lock the remote base up for no reason. I wasn't the only one in the area with these problems either. They were developed by Jim Hughes N2HQI and at one time there was a large number accross NY state. I did receive one from another ham who had one, KA2CTN and never had a bit of trouble with that one for well over a year until I sold it to a friend. 2 weeks later and up till right noe (1 year later) it is still giving us a headache.

John,
I suggest you send at least one more e-mail (maybe a "forward" of your first?), then, as your last e-mail, ask "is anybody home?". It took me three e-mails to get a response from one 2-way radio supplier, all of them more than a week apart. Many people do not check their e-mail any more frequently than every week. 73, Mike, wb6csh - From: kenneyj@...N2HQI) - but haven't received a reply.

The March 1999 73 Magazine has info on 10GHz. In "Above & Beyond" "10 Hgz fun, 1999 update, part 2: The Gunn diode modulator power supply" Looks like you may want to get the Feb issue too for Part 1. Looks like he used the Ramsey FR10 for IF. I'm not into 10 Ghz yet, but this might be interesting to anyone who's been following this thread. Hope this helps. At 10:49 AM 3/25/99 -0500, you wrote:

gunnplexers provide a very nice method of bi-directional linking. They are by their nature capable of full-duplex operation. Add two receivers (30 MHz is reported to work - just crystal up both receivers to the same frequency) to serve as the receiver IF/detector strips. Obtain an AFC voltage from ONE of the receivers and run it back to the voltage regulator of its associated Gunn diode so as to AFC lock that site to the other site [do not AFC both setups - they'll end up chasing each other out of the band]. The Gunn diodes are modulated by providing audio drive to their voltage regulators. Voila! A reasonably simple bi-directional full duplex link. The two transmitters will be synched to each other, separated by the frequency selected as the IF. Now for the customary disclaimer ... this works in theory, and in somebody else's practice - I've never had my hands on two Gunnplexers to try it out, but various publications have reported it to work. With the ready availability of low-band Motorola and GE crystal-controlled mobiles, this should be simple to implement. ......John WB4VVA -----Original Message-----

Yes, the RUS ( Receive Unsquelch Sensor ) is the better one to use. It works with the Channel Guard Decoder ( PL for the Motorola terminology ). It comes out of the Audio Squelch Board on Pin 8 of P904. I've worked with the GE Radios for 20 Years now. John Lloyd, K7JL Kevin K. Custer W3KKC wrote: From: "Kevin K. Custer W3KKC" <kuggie@...> |

10GHZ Link
Kevin Mitchell <[email protected]
Hi All,
I have a couple of 10GHz gunplexers sitting in my radio room that have not been used for anything, at the moment. I brought them at Dayton a few years ago, and wanted to use them for a project, but never got around to doing anything about it. Now, I came across them again and thought maybe I could use them as a full duplex link between the main repeater site and my remote nauto-patch site, or for some other use, with linking as it's purpose. Okay, now that I have this idea, has anyone used 10GHz for linking (full duplex) and if so could you please forward me the information on how you did it. I would like to see them being used for the auto-patch link, this way it will be very hard for someone to find the freq. The information I have so far, from what I have worked out, is that I will have to run them on different freq's. Look forward to the replies. Regards Kevin. ZL1UDD. |

Re: Mastr II Cos question
Henry Clark
I guess that might have been me, Kevin. I use the RX mute line for the COS signal. Here is my reasoning.... The CAS signal goes high anytime the receiver is active. In other words, if you are using the factory Channel Guard board for tone decode, CAS will go high even without the tone. The RUS line will only go high when the proper tone is decoded, however, high is on the order of only ~4.0 vdc or so and can sometimes be tricky about loading. If you use the factory CG board for decode, and have no need to remote control it on/off, this will work. BUT....The RX mute line follows the state of tone/carrier squelch. GE MASTR II's have a CG disable line going to the control head. So.... If you want to use the factory CG board (instead of spending 50 bucks or so on a TS-32P), and be able to remotely control the tone/carrier squelch, use the RX mute line for the COS signal, and tie the CG disable to a user function output on your controller. Grounding the CG disable line will put the MASTR II into carrier mode, while ungrounding it will put the MASTR II into tone mode. And the RX mute line will follow this condition. I am by no means a radio tech, but observations have shown me that the RX mute line is a little slower acting on rapid squelch flutter. Maybe the extra circuits slows it down a little. FWIW, the RX mute will go high (~10 vdc) when the squelch opens, and 0 vdc with the squelch closed. (Darn, I wished I had my manual here!) The RX mute line supplies 10 vdc to the audio amp from the 10v regulator (I think?), and will be pulled to ground with no signal. This is to turn the speaker on/off, and in essence I am doing the same thing except instead of turning the controller COS input on/off. CG disable line simply goes to the mike hang-up box on the control head of the GE. So...by putting the CG disable line to an output on the controller, it is the same as taking the mike off-hook, which then puts the MASTR II into carrier mode. I can't recall the pin # for the RUS line. I do know that it is right beside the CAS line on the pins of the IFAS board, and should be labeled accordingly. The RX mute and the CG disable lines are in the large control cable going to the control head. CAS -- Pin # 9 on IFAS board -- Pin #16 on control plug -- Violet wire in cable RUS -- Pin #8 on IFAS board -- (ONLY FOUND HERE!) RX mute -- Pin # 7 on IFAS board -- Pin # 3 on control plug -- yellow/blue in cable CG disable -- NOT on IFAS board -- Pin # 6 on control plug -- white/green in cable What is the pin number for RUS or RUI, or what ever the hell it'sRUS = Receiver Un Squelched May be a little bigger answer than you intended, but use what you can. If I find any errors, I'll let you know... Henry KC4KZT |

CAS is the 'first' one in line. Carrier Activity Sense. It follows the receiver regardless of CTCSS/CDCSS. J932 pin 18 is one reference I have in my notes. I think that is for the base version. I think the mobile is J904 pin 9. RUS is the 'second' one in line. Receiver UnSquelched. It only goes high when the correct CTCSS/CDCSS is present (in addition to the CAS) This point should be within a few pins of J904 pin 9 (CAS) I don't have the pin numbers in front of me, but I believe J904 is the connector they are on. In any case, it is the connector in front of the audio transformer beside the metering jack. The label right beside the connector (either mobile or base version) indicates RUS, CAS, and all other pinouts. It's been a while since I did any interfacing, but if I recall correctly, CAS will load down *very* easily - even using newer controllers. It can't source much current. If you don't get them from someone else, I'll get them at work tomorrow. I've got 4 Micor manuals here but no Mastr-IIs. 73, Joe, KR3P |

Re: Remote Sites
The Lacko's
To link a few sites you will do i little engineering.
1.) Will the site coverages overlap? 2.) How will the sites be interconnected? ( RF/Phone/Microwave) 3.) How much are you will to spend? If the sites are going to overlap you will need to use different TX frequencies or use VERY expensive high stability transmitters. If there is enough separation between sites you could use the same tx frequency and adjust the power to remove the overlap areas. Crossbanding ( is this a word?) would be the least expensive way to link your sites together. What i have seen is to feed the receivers back to a voter and send it back out to the transmitters. Or crossband back to a hub site and crossband back to the remote site transmitter ( I.E. VHF rx'r at remote site tied to UHF tx'r, transmitting back to hub UHF repeater. The repeater output would be recieved at the remote site and transmitted on VHF.) If you have phone/microwave feed receivers back to voter and then send out to transmitters. Again if you have overlap coverage then you will have to operate on different TX frequencies so there is no same frequency overlap. Hope this helps. Scott |
