Vern, You have an intermittent-duty Micor base station that is equipped with a 110 watt PA, carrier squelch, 1 TX and 1 RX channel, for tone remote control. It does not have the additional filtering and shielding that a repeater model comes with, but you may be able to manage without them. The power amplifier is also not intended for repeater service, although it may work fine if throttled back in power and provided with a cooling fan.
Your Micor station is crystal-controlled, using plug-in devices called channel elements. You don't need to power up the radio to see what frequencies are used; simply remove the small access plates on the back of the exciter and the receiver, and look at the frequency printed on the channel element. Since you have a base station, the channel frequencies will probably be the same, even though the crystal frequencies are different. The transmit or "T" channel element should be a KXN1019B, and the receive or "R" channel element should be a K1005A. You should pull of the module covers and look for any numbers stamped in black ink on the solder side of each board. These numbers identify what the board is and what bandsplit it operates in. Look for any numbers like TRDnnnnx, or TLDnnnnx, THNnnnnx, and so on. Please report back to this list what you find, and we can go from there. You didn't say what band in which you wanted to use your station, but if you plan to move it into the 2m Amateur band from a commercial band, there is some work to do. There is a wealth of material for modifying Micor stations on the RBTIP at www.repeater-Builder.com Very important: Don't start any modifications UNTIL you first verify that your station is working on its original frequencies! Fix any problems first, verify that the station works perfectly, then start making changes. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Friday, March 28, 2008 11:19 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Compa Station Help I have a Compa Station with the model number C73RTB-1106C. I am looking for some help figuring out what this is split, etc and how to make it into a repeater. First things first is that there is no power leads hooked up except for the one to the control board box. I can see where there are places for heavy cables from the power supply to the transmitter. Is there separate power for the receiver or does that come from the ribbon cable? How can I get this thing to key up to see what the TX frequency is? If I find out the TX freq can I sweep the recv side with a freq generator to figure out where it opens up? Are these crystal controlled or can they be adjusted to get the right frequency pair? Thanks, Vern
