We have a few Motorola DP2400 radios and we want to replace the damaged ones with Hytera TC-620.
I have configured them like the image attached but when i pres PTT button only the communication light goes on but no voice is transmitted.
Are this radios compatible with each other, do i need to change anything else?
The Motorola DP2400 is a digital radio capable of analog operation. The Hytera HC-620 is analog only. To communicate, both models must be the same version (UHF or VHF) and the DP2400 must be operating in analog only mode. They must also be able to communicate within the same frequency range.
