I've been testing on a RES radio. Other radio models should also work, hopefully. To keep the radio on without it resetting you'll need to send two ID's

ID: 0x000 (PowerMode)
DLC: 1 or 8
Byte0: 0x61 (i only need to send one byte)
Byte1~7: can be zero's if you're sending all 8 bytes.

ID: 0x1AF (unknown)
DLC: 8
Byte0: 0x01
Byte1: 0xA3
Byte2: 0x00
Byte3: 0xF8
Byte4: 0x96
Byte5: 0xBD
Byte6: 0x1D
Byte7: 0x00
(The bytes above are from a vehicle that I've captured data from. But I can also send all zero's for the 8 bytes and the radio still stays on)

Just finished looking at an REC radio. To keep an REC radio on, my previous post about sending ID 0x4xx still holds true.

Unsure why you need to send the 0x4xx commands. Just need to send the power command about every 100ms. That is all I needed to do for REC, RER or RHR.
