Hi Zack, are you guys on a trunking system or conventional??? If you guys are on the conventional system, you have to enable that on the CPS called ''SIDETONE'' but again, you have to enable the MDC/Emergency as well. Is this your personal radio?? Also, make sure that your not on Simplex, sometimes radio shops set the radio without sidetone/mdc enabled.
