Chris, What is the closest you've operated your R/C to your repeater if your R/C is on 6M, and how close in frequency? Joe M.

RE: [Repeater-Builder] Re: GE Lookout Repeater related info needed.
I looked through my GE microfiche file, and found very little information that is helpful. From what I did find, your radio is a special device that is based upon the PE handheld transceiver modules. It probably was custom-made in a small quantity, since there is no record of it in the microfiche. Only two of the numbers you listed could be traced to an LBI: 4EF50A11 is a 2F, 5W transmitter for 150.8-174 MHz, and is covered in LBI-4528. 4ER59D is a modular receiver for 150.8-174 MHz, and is covered in LBI-30035. All of the other numbers have no references at all, except for these component parts: 19C304504G3 is a DISC 19C311876G4 is an HTF MODULE 19D424569G1 is a REC CONT BD SPL 19C327614G1 is a TX SYST BOARD 19C321632G2 is a BOARD ASM-SPL The part number 19C3200943G1 is invalid- there can only be six digits between the C and the G The PE was a very early GE transceiver, and you may find it extremely difficult to dismantle the modules sufficiently to reach the components you need to change to work on 2m.

Eric, Thanks for all info. Very interesting data you have I was trying to understand with visual inspection. Even box has 4 position for the frequency selection it has only 2 xtal unit on the receiver and 2 xtal unit on the TX board. I was thinking that it was switching xtals between TX and RX board. Can you tell me what are the power supply requirements for these units. Also at the back there are 3 RF connectors (SO 239) one is marked as RX antenna other is just ANT and the third one which is on the TX board says RX RF IN ? I don't have any clue on that. I was thinking to replace OSC xtals with ham band ones and also modify or change the RX filter section. May be I am too much simplifying this work!! I have a nice basement lab (collected a lot of test equipment from ham feasts and eBay) also my electronic knowledge is good enough to handle any circuits however you are absolutely right on this project I was thinking that I am going to deal with classical through the hole components which I was WRONG.

RE: [Repeater-Builder] Maxon sm4450sc
Ian, The CTCSS tones are derived from the timing of ASIC IC107, and are independent of the carrier frequency control circuit. Use your service monitor to sniff around the CPU to see if the clock is running at or very close to 8.2944 MHz. If it is way off, you'll need to replace the X1 crystal, since there is no adjustment.

RE: [Repeater-Builder] Re: GE Lookout Repeater related info needed.
Levent, The component number 19C320943G1 is a SPCL COMP BD. I think it's time to take some pictures of this device, since it seems to be an oddball unit that was not a regular production item. Is there no label or tag on the outside of the box, which might give this thing a name or a model number? Without a clear identification of the whole unit, all we can determine is that it is a special part that incorporates some PE handheld modules. Regarding power requirements, a typical 5-watt radio draws about 2 amperes during transmit. Add 1 amp or so for running the controller, and you can assume that a 5-amp supply will suffice. But, be careful to determine what voltage is required to run this thing, before hooking up your favorite Astron power supply. The unit may require 7.5 or 10 VDC, and you don't know that without more documentation. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of lsasmazel Sent: Saturday, October 17, 2009 4:06 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: GE Lookout Repeater related info needed.

Levent, The pictures do lend credence to the special part theory. Please advise what the two receive and two transmit frequencies are. Do you have any idea what company or agency owned this device? It's a long shot, but it is always (well, sometimes) possible to track down the previous owner, locate the radio shop that maintained it, and possibly identify the documents you need- if they won't just hand them over. Knowing the frequencies used is a giant first step in that process. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of lsasmazel Sent: Saturday, October 17, 2009 4:49 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: GE Lookout Repeater related info needed.

Those frequencies are in the NTIA Federal Government band. Could be Department of Interior, the military, or US Forest Service. Of course, since NTIA has already switched to narrowband operation, the channels in the Lookout Repeater are no longer authorized for their original purpose, and the equipment is not convertible to narrowband. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of lsasmazel Sent: Saturday, October 17, 2009 5:19 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: GE Lookout Repeater related info needed.
