[Repeater-Builder] new to Micor
Hello AllI have a UHF Micor RT station that was a surplus 460 police repeater, single reciever, 75 watt PA. I am almost sure it was setup for DC control. Here is my generic questains. I have built quite a few repeaters but never a Micor. Of course I need to make sure the station will operate as-is before I convert it to Amateur use. I would like some suggestions for like backplane jumper placement, what stock cards to use, or just maybe some sort of logical plan of attack. For now, I do not have the tone remote, and I have the station control module, ( with all switches in defeat mode, and the 4-wire line driver cards installed. The most I am getting is weak audio that I cannot squelch from the reciever controls, but only with the line driver card installed. (I have a generic Moto speaker hooked to the pins on the backplane) If I install the squelch gate card all audio goes away, and I dont seem to get any TX from the N/C switch on the station control card throuh the wattmeter. I do have all the manuals, and I do have a good service monitor and test gear. The goal is to verify proper stock operation, then do the mods for a ham repeater. I just have zero experiance with the Micor and need a planThanks Andy T. KC8EVM Yahoo! Mail Bring photos to life! New PhotoMail makes sharing a breeze. YAHOO!

Re: [Repeater-Builder] new to Micor
The backplane needs jumpers 1,4,5 only.. remove all others. I can email you the complete conversion process that I use, or fax it to you. Here is a good start on things. I've done about 15 of them so far with success.if you plan to use a controller, then the only card you will need is the station control card, with the correct jumper arrangement. it is normal to lose rx audio with the wireline driver card out, but a jumper between pins 6 and 14 of J2, the long strip of exposed pins on the lower part of the backplanewill return your audio. The station card needs JU2 thru 9 in, and JU10 out. You will need to add an IRC510 mosfet to J5, the row of pins on the upper part of the backplane, to switch pins 19 and 20 together on transmit, getting the voltage frompin 25 of the same J5. lance N2HBA - Original Message - From: andy thrasher To: Repeater-Builder@yahoogroups.com Sent: Wednesday, March 08, 2006 6:20 PM Subject: [Repeater-Builder] new to Micor Hello All I have a UHF Micor RT station that was a surplus 460 police repeater, single reciever, 75 watt PA.

Re: [Repeater-Builder] new to Micor
Thanks Capt. LanceThat is some great detailed info which I will use. Yes, I will be using an external controller (CAT 300DXL) , and my goal is to do the conversion on the audio squelch board per Kevins article on RBTIP. Hopefully eliminating most if not all the station cards. BTW this is a compastation unified chassis. At present I just want to see if I can verify RX and TX per specs. Being a GE guy all my repeater-ham life its fun tackling a new type of machine!

That jumper hooks receiver audio to the speaker amplifier input. If you mount a SPDT toggle switch under the volume and squelch controls with the armature on the amplifier input and one side on the receiver output and the other side on the transmitter audio input then you can monitor either audio source (i.e in the transmitter position you can hear the controller responses - the IDer, the reset beep, the function complete acknowledgement, etc. Or put a rotary switch in and use the other positions to monitor audio from NOAA receivers, to / from link receivers/transmitters, to/from remote bases, etc. The station card needs JU2 thru 9 in, and JU10 out. You will need to add an IRC510 mosfet to J5, the row of pins on the upper part of the backplane, to switch pins 19 and 20 together on transmit, getting the voltage frompin 25 of the same J5. That just switches the transmitter channel element on and off. You can use the existing antenna relay switching transistor on the station card (repeaters have no antenna relay, so it's unused) to do the same thing. Three days ago, (March 6th, about 4:30pm) I did a posting on this same topic to a gentleman who was asking about hooking a unified station to an Arcom 210 controller. Rather than post a long brain dump again , I suggest that you backstep and read it. Mike WA6ILQ YAHOO! GROUPS LINKS Visit your group "Repeater-Builder" on the web.
