[Eric] Nowhere other than the minimal comments in the source.

[Eric] They do indeed need to match. No checksum, but we currently check
this by making sure that the firmware being used matches what PowerSDR is
expecting.

[Eric] All are in the files mentioned (see FWC folder in the source). The
units for the frequency are in MHz.

[Eric] You basically presented the 2 best options. If you're going to use
Windows and C#, then it is probably best to just implement something based
on the existing C# fwc code. If you are going to do something in another
OS, OR want more flexibility in languages, it probably makes sense to
implement it at the MIDI layer.

[Eric] In the current instantiation of the software, yes.
