Description

This handheld came from factory with this version, and it seems it has some minor differences that prevents being used as is currently in CHIRP.

So far, I have identified at least the following changes:

  • The identification code is now "00 00 00 2c 00 20 d8 04"
  • DTMF codes have been extended from 5 to 7 digits (see offset 0xA020 where the DTMF is "2020202")
  • The PTT ID option is now at 0x900B (found by diffing "factory.img" with "factory_pttboth.img"). 0xA006 (as in the other radios) is used for something else, and altering it seems to cause the radio to transmit "123" on end-of-transmission instead of the correct code (???).

The official RT-470X programming tools seems to be unaware of these changes in the v2 firmware, and uses the v1 layout regardless, causing the DTMF lengths to be limited and corruption in the 0xA006 which causes also the aforementioned issue with DTMF 123.

Attached are two files:

  • "factory.img": image dumped from a reset device
  • "factory_pttboth.img": reset device, but the PTT ID mode has been changed from OFF to BOTH. No other changes.
