CPI and MotoTRBO
We just installed two local CPI remotes and a control box in a brand new MotoTRBO system. CPI staff was very helpful in selecting the right models. However, on digital the remotes sound like crap. Analog is okay, but the audio from the CPI remote is so "thin" and makes the dispatcher sound like a robot. Analog works fine...had to switch the customer back from digital it was that bad. Not sure if it is CPI, DMR, or a combination. Based on this experience I can only recommend it for analog.
Regardless, side by side CPI vs. Motorola OEM desk microphone, the Motorola sounds 10 times better than the CPI remote, analog or digital.
