Minitor IIIIIIIVMinitor IIIIIIIVMinitor IThese units are not synthesized. They use crystals for the RF frequency and use Vibrasponder reeds for tone selection. There is nothing programmable about it. Inside the case they all have in common two boards, the RF board, and the audio board. Obviously the RF boards are band specific, and come in low band, highband, and UHF models. Generally speaking you can move these radios throughout their entire band although you may need to remove the ferrites and replace them with brass set screws if you are moving them upward in frequency past their design limits. The audio boards come in four flavors carier squelch only, PL only RARE,four tone and carrier EXTREMELY RARE, and two tone and carrier. The latter is by far the most common. The Vibrasonder reeds can have their decode frequency changed by adding a bit of solder to lower the frequency and shave off a bit to raise the frequency. With a scope on one of the three pins of the reed not sure which one it is inject the tone you wish to decode into the receiver and tune the reed for max output. In 2 tone mode, they can decode 2 sequences with one common tone. Jumpers can be strapped to select which fequency is used in alert mode there is a 3 pos switch, mon 1, mon 2, alert. The Minitor I pager also comes in a 2 tone model that does not have the selector switch for monitoralert. Just a bare bones two tone alert.

Minitor VI 6 pagers from Motorola, get a free Programming kit when you buy 5 or more Minitor VI pagers. Trade in your old pagers for credit towards a new Motorola. The rubber gasket that covers the top of the pager under the metal frame has a hole for the switch, but underneath it is just a transistor and a few jumpers in the area of where the switch is supposed to be. This is actually a Motorola Director pager, its model number is CA0. EAB2. 46. 8AA. It was designed as an EMSwide area tone and voice pager and was used in many markets. There is also a Director II model A0. XKC2. 46. 8AA or A0. ZVC2. 46. 8AA for stored voice model. These pagers are fairly common with the fire depts in Ontario since many FDs use shared channels. There was a separate board that went into the section that usually held the reeds that gave the Minitor I carrier squelch capability. You could not have selective call and carrier squelch in the same radio. In a Minitor I, the reeds are right next to the battery compartment. The reed closest to the batteries is A tone and the reed next closest to the speaker is the B tone. Minitor IIThese units are not synthesized. They use crystals for the RF frequency and a Perma Code active filter for the decode frequency. To identify which reed is which in the Minitor II, take the case off, and hold it with the reeds or spaces for facing you with the control knobs facing away. The tones go from left to right slot 1 A tone, slot 2 B. C tone. They have the option for a second channel, and the signalling is programmable at least in later models. There is no option to do a PL squelch. Tone Code Sets. Set. Option. Tone Code. Alert Type. 1R4. 68. A BInterrupt  A CInterrupt  Long BContinuous  Long CContinuous. R1. 30.

Take a look at this chart to see how to set it up. Table 1 lists the alert mode tone code sets available. The standard monitor is supplied with tone code set 4 A B interrupt alert. The other tone code sets are options. Monitors equipped with the On DutyOff Duty option use a tone code set that includes tone C Set 1, 2, 3, 5, 7, 8, or 9. In the On Duty mode, the monitor responds to all the tone codes in the selected tone set. In the Off Duty mode, the monitor does not respond to any code that contains a C tone, but does respond to all other codes in the selected set. Tables 2 through 4 list the jumper connections for the tone code sets and for the standard and optional features. Table 1. Tone Code Sets. Set. Option. Tone Code. Alert Type. 1R4. 68.
