[TenTec] Original Orion Firmware

I have two small items, shouldn't be difficult to fix.

1. In band stacking registers please preserve the full filter state.
    Currently only BW is preserved, and PBT is not.
    This makes it very inconvenient to switch from CW (normally PBT = 0 Hz)
    to SSB (normally PBT=100..300 Hz), and vice versa.

2. Change AGC Threshold unit from uV to dBm and use 1 dB steps.
    If changing units is inconvenient, please at least make some sense
    of the step size, which is unbelievably messy now.
