This could be evolved into a general purpose VCO/VFO/IF replacement for a variety of popular radios expanding their capabilities to the digital realm.
The clock generator for the alpha version of PB121 will be a SI5351 from Adafruit. These are available in large quantities cheaply and $7.95 in single quantities. It provides 3 clock outputs and is designed for RF PLL synthesis. I have used Silicon Labs ClockBuilder Pro to build a suitable Band Plan for the chip to generate all the signals needed to run the HR2510 RF deck. More info can be found in the overview of the Adafruit SI5351 Breakout.
