Why does my Motorola CP185 have no receive audio, or the receiver doesn't unmute?
If you are experiencing no receive audio or the receiver does not unmute on your Motorola Two-Way Radio, check if the transmitted signal matches the receiver configuration (PL, DPL, etc.). Also, with the monitor function enabled, check if the radio can be unmuted.
Why is the audio distorted or not loud enough on my Motorola CP185 Two-Way Radio?
If the audio from your Motorola Two-Way Radio is distorted or not loud enough, it might be due to the synthesizer not being on frequency. Check the synthesizer frequency by measuring the transmitter frequency and realign it if it's off by more than ±150 Hz (VHF) or ±500 Hz (UHF).
Why does my Motorola Two-Way Radio have poor RF sensitivity?
Poor RF sensitivity in your Motorola Two-Way Radio can be caused by several factors: * The synthesizer not being on frequency: Check the synthesizer frequency by measuring the transmitter frequency; realign if off by more than ±150 Hz (VHF), ±500 Hz (UHF). * Receiver front end tuning: Check RF front-end tuning for optimum sensitivity using the tuner.
