You can easily figure out the connections to the Mitrek test sockets by examining the Mitrek "Super Consolette" test meter circuit here:
<www.repeater-builder.com/motorola/test-sets/hln4138a-mitrek-consolette-mete ring-kit.pdf> All you need is a meter with a 50 uA movement and a 17,500 ohm resistor. A sensitive analog meter is far superior to a digital meter for this purpose, since you can easily see the voltage peaks- many of which are quite subtle. Since I have many Mitreks to convert and align, I'm building a "Mitrek Test Box" based upon the above circuit, and using a couple of the 12-pin plugs P/N 0180754A26 shown here, about 1/3 down the page: <www.repeater-builder.com/motorola/test-sets/test-set-index.html> My test cables come from an RS-232 DE-9M/DE-9F data extension cord, which has nine stranded wires with an overall shield. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of sgreact47 Sent: Friday, December 28, 2007 8:48 PM To: [email protected] Subject: [Repeater-Builder] Re: Mitrek Transmitter Tuning The accual meter circuit IS one volt full scale at 50uA. The Motorola test sets all used a 19K (give or take) resistor in series with the 50uA meter. That = 20K resistance. Measurements are refered to the 0 to 50 scale.
