What Mobiles are capable of Channel Steering over Tone Remote?? I need to replace a older Desktrac with a TRA in it with something Narrowband capable. My Setup right now is an MC2000 connected to a Desktrac controlling 12 Frequencies and Scan. I want to go to 100W, but am not sure if any of the 100W mobiles are capable of remote channel steering. I was also thinking of using a CDM1250 and a TRA... Any thoughts?? Quantar or MTR2000 out of the question....
Thanks

Hello :
I may be a bit off what you need but ill throw an idea up for all to view and see if by chance this could be an option for you.
I do know for a fact that the Motorola M216 mobiles had channel steering capabitlies per there design.
They are 25 khz wide band as is but Motorola does sell a 12.5 khz narrow band conversion kit that is compatible with the M216 .
I know because i have the 12.5 n/b kits on hand in stock and it mentions being compatible with the M216 mobile.
Normaly the M216 had as factory 16 ch capability but can go to 32 ch per conversion.
As for 100 watts - Well no - But 40 or 45 watt depending on whether your looking for VHF or UHF .
The M216 was made in the 800 mhz split as well and i have them also here in used inventory as the 15 watt version but can upgrade to the 35 watt version if need be.
Id consider using the mobile as an exciter for a 100 watt linear amp to get 100 watt out if you truly need that sort of pep .
If by chance you feel the above is acceptable and others feel im thinking straight on this one - then PM or email me as i have UHF / 800 mhz M216 mobiles available complete in my inventory.
If by chance you need a VHF M216 mobile i can put together a VHF M216 with the prom version that supports channel steering and reiniate as a M216 mobile rather than the Maxtrac 300 which does not have channel steering abilities.

The Kenwood TK-790, and TK 5710 have BCD inputs. You can select up to 16 channels that way.

CDM mobiles can do channel steering as well, 750, 1250, 1550.

I don't know about any 110 watt mobiles.

I forget exactly how it worked, but MCS2000 Model III radios and Astro Spectra consolettes could be interfaced through a digital junction box and then be operated by up to several MC series remotes, but I think it was all DC.

There are a number of radios on the current playing field that can be remotely channel controlled. I would start with
the tone remote adapters. Most of the companies that supply them have service tech notes on how to connect them
with different radios.

Not knowing what you have to work with or what your budget is, you are kind of leaving us in the blind.

Along with all this, there is a point you should be aware of if you manage to obtain one of the Motorola consolettes.
There is a frequency channel glitch that mother M has made when you use this radio. Channels 3 and 4 are really
channels 7 and 8. Channels 7 and 8 are really channels 3 and 4. Kind of blew my mind the first time I ran into
this radio and used it on a tone remote system.

Another point to consider is that most of the Motorola tone remote systems only have 8 channels. You can
get some remote adapters that will go to 16 channels. CPI is one of them. Tessco is a good source of the
tone remote adapters.

While we are talking about tone remote control, remember that you are limited as to what levels you can place onto
the telephone lines if you are using any. Do not go above 0 db for your high levels. If you adjust the idle PTT tone
level to some place between a -22 db and a -25 db, you will stay below the high level limits. On the bottom side,
if you get down to a -35 db for the low level guard tone (PTT), you are approaching the bottom side of the "don't
work reliable" zone. Most radios stop detecting the tone at a -40 db.

Hope this gives you some food for thought.

The 4-channel M1225 is also capable of channel steering via tone remote. They work well with the ITA2000A adapter and ITR1000 deskset.
