Thanks to Ted for posting that he has three of these kits in stock. A caution to those that are buying this kit... they are the option kits for the Motrac/Motran/Mocom-70 vintage tabletop base stations. To be used on just a Mitrek you will need to mentally swap all the "receiver metering point #1" and "receiver metering point #2" instructions. Or make it easy on yourself and swap pins 1 and 2 on the receiver plug (easy way is to unsolder the two wires on the switch end and swap there), or you can add a DPDT toggle switch connected to reverse the two pins. The new switch should be labeled "Mitrek" and "Pre-Mitrek" (or "Motrac/Motran/Mocom-70"). The manual for the Mitrek version of these kits is at <http://www.repeater-builder.com/mitrek/mitrek-consolette-metering-kit-hln4138a.pdf>. Note that they contain a 17.5k precision resistor (Moto part number 6-855337). If you are building your own and the meter you are using has a different internal resistance you will have to tweak the value. Mike WA6ILQ
