CDM1250, M1225 and R.I.C.K.

I have a customer currently running a light duty repeater using 2 M10 mobiles and a R.I.C.K. Due to narrow banding, they must be replaced. They have an extra M1225 and CDM1250 laying around. Is there any reason these 2 radios couldn't be connected to the R.I.C.K. and the customer be back in business? I don't have a lot of R.I.C.K. experience so I thought I'd check here with some of you who are more familiar with them. To me this would be a much more economical solution that purchasing a full blown repeater since they already own these 2 mobiles.
Thanks in advance!

Technically no. It will work. You just have to set up the accessory plugs correctly, and then set levels. However, the CDM will probably not fit in the current repeater housing. You should also determine if the existing power supply will support the CDM tx demand.

Luckily in this application there is not a repeater housing so space is not an issue. The power supply is also sufficient for the CDM to operate.

Well, in that case, I guess you just have to determine which radio to make tx and rx. The m1225 will be closer in performance to the existing m10's. The cdm has a better receiver, and the m10's could be used as spare rfpa sections for the 1225. I suggest using the cdm as rx, and the 1225 as tx.

Wes,
I have the Accessory Connector pages from the service manuals as PDF's if you want them.

As much as I respect Bill's opinions and input, I'd have to go the other way: CDM for transmit and 1225 for receive. I've used 1225s as receivers in simple GR-type repeaters many times and they have extremely hot receivers, almost on par with a Maxtrac. The CDM also has a larger heat sink surface area and doesn't get quite as hot in an extended transmit duty cycle, although it still needs a fan blowing on it.

Correct the CDM for TX and the M1225 for RX.
The R.I.C.K. is a poor design and obsolete, we have not used them since the mid 90's. They were replaced with the Repeater Modules that were a plug and play interface, now no longer made. Now we use ID-O-Matic II boards. The ID-OMatic does all the repeater interface functions plus ID and timeout timer.
By the way no failures on any of them in service, Commercial, Ham, or GMRS.
