Motorola HT1250 LS+ UHF2

Purchase Date:

June 3rd, 2026

Description:

This is by far the radio I've done the most modifications to. I modified the internal EEPROM of this radio to make it function exactly like a standard HT1250. I bought this radio from a friend and found that it didn't support MDC or QC2 on conventional and only could hold 18 conventional channels. So I dove into the HEX editor and modded the radio!

Motorola Trunking Talk Permit Tone.m4a

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.m4a

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"

389.0 + 410.0 QC2.m4a

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.

DTMF.mp3

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".
