I am seeking a clean and complete paper copy of the GE Datafile Bulletin 10008-5 entitled, "Measuring FM Deviation by the Bessel Null Method" written by James J. Carrington and published by General Electric in November 1967. This is a 9-page document that provides an excellent tutorial about using

Before you shell out the $$ you will want to ask the seller if it has the male or female on the RX box. They were built both ways (i.e. backplane=male,RX=fem or backplane=fem and RX=male) and are a bit of a pain to change. If you are in no hurry you may want to wait for a RX with the right sex. M

Re: [Repeater-Builder] Micor Ribbon Cable

It's a common problem, Moto. fixed it by coming out with the unified chassis which eliminated the ribbon cable. You might try making up jumper wires to eliminate the ribbon, you can get edge connectors if you wish, or tear the ribbon apart for the plugs and start over. It's a pain, but it works.
