Actually, I believe the frequency shift is done in the MCU firmware.
Control of the synthesizers is what is needed.
Those "few lines of code" can be problematic (not with what is intended,
but other aspects that it interfered with) - that is why the firmware is
tested in-house (or by a few out-of-house field testers) before it is
even released as a beta version.

All done in DSP most likely. Simpler than doing the same thing in an analog
radio.

Thanks, Don. Harder to implement, but safer.
