Reasons you would want the LF boards:
- The Basic boards don't work below about 1 MHz, and you have signals
down to DC.  One use would be for LF and VLF radio.  Also, if you have
an external RF section which uses direct conversion, you need the LF boards.

- The LF boards have some of their own antialias filtering.

- The LFTX will put out more power than the BasicTX.

Reason you would want the Basic boards:
- You need to deal with signals over 30 MHz.
