How to Channel Steer Radius M1225

Post by bsmanwaring »

I have a 20/24 ch Radius M1225. It is connected to a ITA2000A - GAI-Tronics tone remote (essentially the same as the Motorola L3276). I thought that I would be able to channel steer the M1225 using the programming of the accessory pins in the rear. I have done this previously on the GM300s before they were replaced due to narrowbanding. I am not finding the options for channel steering in the RSS for the 1225 however. I did run across something on the internet which said only the 4 ch 1225 radios had channel steer capabilities. Anyone have any suggestions on a way to channel steer the 20 ch 1225 from a tone remote???

Thanks!!!

I looked at codeplugs for both 4 ch. and 20/24 ch. models and only the 4 ch. had channel steering options in the acc. settings, so that confirms what you read. I don't know of any way to make the 20 ch. radios do it, unless someone else knows of a hack you're probably going to have to find another model radio that does support it.

I installed quite a few M1225s as firehouse consoles back in the day, the only ones that understood function tones were the 4-channel models. I think we used a TNA200 connected to an ITR2000A.

Hello:
Interesting you mentioned you did ch steering with the GM300 and since narrow banding you must have replaced the GM300 with the M1225.
Ok consider this :
The GM300 was manufactured from the Motorola factory in narrow band version as well as wide band.
So my question is - Could you use a Motorola factory GM300 narrow band mobile and ch steer to get 16ch or do the 40ch hex edit mod to get more channels ?
This would give you 16ch for sure and with the 40ch hex edit mod youd get 40 channels.
If you need the vhf factory narrow or uhf factory narrow band I have both in inventory at the moment.
Just a thought for you to think on if you run into issues with the m1225 not being enough.

We replaced all our GM300's with CDM1250's for Channel steering on our tone remote adapters when it came time to narrowband them.
