Description:
This discontinued radio surprised me with the fact that it supports MODAT (an old signaling standard by Motorola). It's a very cool radio. It is feeling it's age though...

Sound Effects:
Talk Permit Tone
This tone is used to indicate to the user that they are clear to talk on a trunked channel. It can be programmed on trunked systems. It indicates that the radio has authenticated with the system controller and you are free to talk on the system.
MDC-1200 ID Burst
This is what MDC-1200 sounds like when listened to in a raw transmission. MDC-1200 sends a 4 digit ID number over the air at the start, end, or both the start and end of a transmission. This specific ID burst contains the ID "0612"
Quick-Call 2
This is an example of what a Quick-Call 2 broadcast can sound like. Quick-Call 2 uses 2 different tones as a paging system typically in public safety radio systems. This specific audio has the tones 389.0 Hz and 410.0 Hz.
MODAT ID Burst
This is an example of what a MODAT ID burst can sound like. The data transmission is slower than MDC-1200 which allows the sound of the ID burst to change when the broadcasted ID is changed. This specific ID burst contains the ID "612"
DTMF
This is an example of what a DTMF radio ID can sound like. DTMF is the same tone technology used on telephones to dial phone numbers. This specific audio has the numbers "0612".
