RICK crossband with CDM750 and maxtrac settings bi-directional

[wcu02mpa]

So I am trying to set up a RICK crossband repeater (experimental only) with a lowband 29-36 MHz maxtrac and a VHF CDM750 (I have done this set-up before when the band is open and it works). I am quite proficient at setting up each of these in a RICK set-up with the same type of radios. i.e. Maxtrac-maxtrac and CDM-CDM. This is the first time I have tried to mix them. The maxtrac is set as RX radio and CDM is set as TX. Both of them work fine when paired with another similar radio so that works. Can someone guide me on how to properly mix these?

The manual is pretty clear. Did you make all the needed changes in the CDM for COR ?

Actually, no the manual isn't clear. You show me in the factory RICK manual where it mentions WARIS series radios. I can't seem to locate that page. The manual states nothing about combining the two radios.

The manual was written for the maxtrac. If the pins are programmed as the maxtrac any CDM, M1225, CM200, PM400 will work with the RICK. There are 5 basic pins you need from any radio. PTT, Mic Audio, Discriminator Audio and COR and Ground. The CDM series supports all these pins. Pin numbers are the same on all the radios. If the radio is programmed correctly it will work fine.

You will need to look in the CDM manual to set up the accy pins on the CDM series radios. The RICK "manual" was written last century and not very well written at that.

Thanks.....just needed to know which manual

 

[wcu02mpa]

Got it. The maxtrac setting for RX are as the RICK manual states. The TX CDM setting are Pin-3: External mic PTT, Pin-8" PL and CSQ detect.

The crossband repeater is alive and well. Thanks.....

@wcu02mpa what @cmdrwill isn't telling you, is that he is the RICK's biggest fan.

The R.I.C.K. was replaced a looong time ago. By the little box between the two radios.

Only reason I am even using a RICK is a got a surplus of them a few years ago at a Hamfest.

I will bite.....what is that?

I'm intrigued as well...

@cmdrwill is that an older ID-O-Matic?

 

[cmdrwill]

No that IS like a RICK but NOT made by Motorola.
