@ -15,7 +15,8 @@ I am interested in seeing a frequency analysis into a dummy load of the radio on
# TA3782F
Most of the components in this radio are well known off the shelf stuff. However this TA3782F MCU is not and there is practically no documentation for it. I initially believed this to be some MCU utilizing an Arm Cortex-M4 core, but now I'm almost convinced this is not the case. I'm leaning toward some kind of Intel 8051 MCU architecture as this is providing some meaningful disassembly in IDA Pro.

This is providing some meaningful disassembly in IDA Pro.
Here's a typical snippet of disassembly of the firmware image assuming Intel 8051 code architecture
