motorola tone remote

Postby nb1h » Wed Oct 28, 2009 8:09 am

Hello

I have a motorola T1605CM that I plan on connecting to my m1225 radio. I am aware that I need a termination panel in the middle, but I'm pretty new at this so I'm looking for some info. I can find plenty of info online about the termination panel so I'm mroe concerned about the remote itself.

I can't find anything on the net about the T1605Cm. Is this part of a larger series that I can research? How do I tell if I have a DC remote or a tone remote? It has a F1/F2 switch, and I'm wondering if the unit is upgradable with any other switches (high/low power or repeater/direct maybe)?

There are a couple of ways to figure out what you have. One way would be to take a current meter and a
resistor of say 100 to maybe 500 ohms and connect them in series with the output terminals. Key the mic
and see if you see something like 5 ma on the current meter. If you see any current, you have a DC remote.
The second way would be to cap couple an audio amp across the output terminals and listen for a series of
short tones as you first key the remote. If you hear a couple of short tone bursts then it is a tome remote.
These tones will be 120 milliseconds of 2175 Hz, then 40 milliseconds of 1950 Hz tone (F1). If you have a good
audio amp, you will hear a very low level 2175 Hz tone for the duration of keeping the remote keyed.

Hope this will let you figure out what you have.

Probably going to be difficult to find parts for the T1600 series remotes. IIRC, they supported a T8R8 configuration at maximum. They can also be equipped with features such as DVP ON/OFF, Alert Tone, a clock, a VU meter (analog), PL select, I've seen units with DTMF pads, etc.

Best to scour eBay for things like that.

If you want something a bit more modern and still affordable and programmable, have a look at the T5600 series remotes.
