Primary hit on using a Nano for AGC is the time it takes to drive a digital pot via the i2c bus,
especially since i2c is also running the si5351 and perhaps a display.
Don't have enough pins to go spi, unless it's a second Nano.
Regardless, way easier to do it with 2 or 3 FET's than it is to trip over software timing every
with every hack to the Nano firmware, or to add an extra processor.

This isn't requiring the micro controller to do any heavy duty DSP type processing. I think it would be very fast. An Arduino Nano may be fast enough.
