Connecting a Motorola 1474A Tone Remote to an XTL 5K Base

Post by WCHija »

I have a Motorola 1474A Tone Remote to an XTL 5K that I use as a base. My remote is set up as a two wire. Is there a way to connect it to my XTL?

Sure...you need a 'tone remote adaptor' in between. It connects to the radio using the standard PTT, ground, & audio pins. The remote feeds into the adaptor, which detects & notches out the guardtone, keys the radio & passes the audio. You can get them from Motorola, or any number of other manufacturers (Zetron, CPI, etc).

Can I make a suggestion that you provide the complete model number of the remote, like TLN-1474A. That
way the rest of us can make sure any answers that may be forth coming are correct.

With that said, you will more than likely need to use a tone remote adapter and cable it up to the XTL
radio. Again there are several versions of this radio. Is it a front mount, trunk mount low / medium power
or a high power trunk mount? The connections that you will need to use could be different, depending
on the version of the radio. A front mount radio will force you to use the 26 pin funky looking connector
on the rear of the radio. This you will have to obtain from Motorola. If you have a trunk mount, then
there is a chance you can use the DB25 connector on the front of the radio. This connector is a standard
connector that can be obtained from just about any place that caters to the electronics industry.

You will also need to obtain a tone remote adapter that will convert the audio control tones into a PTT
signal and also interface the RX and TX audio to the radio. There are a number of companies that
provide these units. Not knowing where you obtain your radio parts from, it may be hard to make any
suggestions.

Don't forget that you will need a 12 volt power supply to run the radio. It needs enough current capacity
to hold the voltage when the radio is in transmit. theis will depend on the transmit power level of the radio.

The label on the remote says L1474A. It has an AC power supply attached and 4 conductor phone wire coming out of it. The XTL is a mid power dash mount.
