Does the "tune" function actually do anything for the BASIC_RX? Does it
just set the DDC

For example, if I have a quadrature HF receiver, centered at let's say
20MHz, with 4MHz either
  side of 20MHz, can I use "tune" and setting the decimation to pick out
a particular chunk.

Let's say I wanted the 250KHz "chunk" that's +500KHz from the center
frequency, would I set
  the decimation to 256, and ask "tune" for 500KHz?
