MMmyyeeaah... but I was hoping for an easy solution that didn't involve me blowing $150 on something I would use for three days.

I have a bunch of Radius M1225 radios in my shop. I need to use the AARMN4026B DTMF microphones with these radios for a small project I'm working on, but naturally, they don't work. These DTMF mics work with CDM750s, but I don't have those radios handy, and I can't really go buy one for this project ...
