Vern, Most likely tells you the TX is on 154.335 meaning it would be a 150-160 MHz split. On the solder side of the PCBs you should see a TLD number, something like this and if the last digit is a 2 it is 150-160 for both exciter and rcvr. 73, ron, n9ee/r From: [EMAIL PROTECTED] Date: 2008/03/31 Mon PM 01:49:37 CDT To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: Compa Station Help Well the exciter element was still in there and it is 154.355.

Re: [Repeater-Builder] Re: Compa Station Help
Actually, I wouldn't be too concerned about the condition of the rest of the station. You might not be, and I would not be concerned if I had the station or was considering it. I do not know what the original poster's level of experience is, thus my comment. If I was looking at this station I would see a good supply of spare parts, and/or a possible conversion to 220 since it reportedly has a high range transmitter. I would not consider this station a good candidate for a first time project. With no channel elements and a high split radio it will be hard to determine if the station has any problems BEFORE an attempt is made to change frequency. Simply grabbing a set of elements and restuffing them is a sure way to add to your overall level of frustration/stress. If I were going to try to do anything with this unit I would want to find a set of channel elements in the high range. I would then attempt to get the station working in the range that it was built for. Find and if possible fix any issues that are present. Determine what is needed to convert to the lower range. THEN AND ONLY THEN would I attempt to change the frequency of the radio. No, changing the frequency range in which the radio operates is not rocket science, it simply takes a service manual, proper test equipment, time, parts, patience, an understanding of what is going on, and a willingness to learn. Now back to repeater-building. MIlt N3LTQ
Re: Re: [Repeater-Builder] Re: Compa Station Help
Milt, Very good advice. I would not even try to move the unit down with the existing boards if they are the higher split. If going to 222 then would be something to start with. If putting on 2 meters would be nice to pick up a mobile for 136-150 range and simple unplug the boards...well exciter and receiver, and remove these from the mobile. They just plug in. Of course finding a 136-150 is difficult, but Canada did use this band more and I see other equipment like the GEs in this range. Milt, you and others on this board, and I started messing with the Micor a few years back. It is obvious from all the reply's that many have worked with the Micor. The commercial guys couple decades back. Of course then we could not afford the $3000+ for one so many used Motracs. It was fun working with the Micor. Once got a manual (Mot made excellent manuals) one could really work with them, learned how to work with them and as with many Hams enjoy this kind of thing.

Re: Re: [Repeater-Builder] Re: Compa Station Help
Vern, There are basically 2 power leads from the power supply. 1 is a multi-wire cable that plugs into the card cage usually and the other is a large, #12, two wire that goes from the heavy terminal on the rear of the supply to the main chassis set of terminals, usually in the upper right. The multi-wire cable hopefully is there. It is just wirings coming out of the PS chassis and carries the low current 9.6V and 13.8V. The larger 2 wire is easy to make and supplies the power for the PA. 73, ron, n9ee/r From: [EMAIL PROTECTED] Date: 2008/03/29 Sat AM 07:51:35 CDT To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: Compa Station Help The reason the power supply leads are missing is that I got it from the local used supply store.
