Justin - you did the right thing in that SB-303.? The number of frequencies that can be readily switched with the ProgRock2 is a maximum of eight.? Technically it can output 24 pre-programmed frequencies (3 banks of 8 frequencies each), but switching the bank output when using the device to replace a heterodyne oscillator section where more than 8 crystals are involved is so difficult, it's best to just use the Arduino.? I did the same in a SB-313.

Oh, I received and SB-303 last year that had a lot of dead crystals so replaced them all with an Arduino andsi5351 module...
