| Component | Requirement | Notes | |-----------|-------------|-------| | | Motorola RSS R06.12.00+ (DOS-based) | Runs on true DOS or DOSBox. Not Windows native. | | Programming Cable | Aftermarket or OEM RIB-less cable for GM950 | Uses a DB9 (serial) connector. Requires a Max232 level shifter (unlike Maxtrac cables). | | Computer | Old PC with real serial port (COM) or a USB-to-serial adapter with FTDI chipset | Laptops with USB-only need a quality adapter (e.g., FTDI, not Prolific). |

No. CHIRP does not support the Motorola GM950. The GM950 protocol is proprietary, encrypted in the codeplug structure. Do not attempt to use generic software; you will only corrupt your radio. It’s legendary for its durability, but its brain

He opened the programming interface. The screen looked like a spreadsheet designed by a sadist. Channel 1: 151.625 MHz, 25 kHz deviation, carrier squelch, high power (25W). Channel 2: 151.835 MHz, same. Channel 3: 155.400 MHz, but with a strange PL tone of 192.8 Hz.

Pro tip: The GM950 is slow to program (baud rate 9600). If you get "Communication Error," slow down your PC’s CPU emulation or use DOSBox with appropriate cycle settings.

He frowned. 192.8 Hz was unusual. Standard tones were 100.0, 123.0, 151.4, 173.8, 203.5. 192.8 was a Motorola oddball, rarely used. It meant someone wanted privacy but also wanted to be found by only a very specific group.
