564c35f397 Modifications, mainly based on a code walkthrough as well as adding some
debugging output.  Compiles, but untested.

9b7095a6e3 Added some filters and speech compressor. Compiles, but not tested.
About to try some extreme re-architecting, so...

7aa2cbc1c4 Added some basic FIR filter code (2.8 khz SSB filter).
Biggest thing, discovered that I needed to increase AudioMemory to 16 to
fix some "motorboating" that seemed to startup anytime I transmitted
through USB.

9c1a490963 Fixed comms between the Raduino and the IOP. Implemented the wrapper
that allows messages to go back from the IOP to Raduino.  I don't know
if actual CAT from the PC works currently, however.

ccae79925b Updated to include iopcomm.h/iopcomm.cpp, common to both the IOP and the
Raduino.  It was intended to be more extensive, but I had to roll some
of it back.  Mostly just sharing of enums/types currently.

Currently in "factory calibration" mode.  Comms (CAT) in normal mode
needs to be re-checked.

Added two tone test mode, with two new modes available via Raduino menu:
TTL and TTU.

Using test mode, I'm thinking that the proper TX output calibration,
assuming a full-scale 700/1900 test tone, is either:

0.061  (which I believe gives a 25 mV RMS output), or
~0.100 (which is just before the audio starts to distort, in terms of
visible harmonics in the spectrum at the 45 MHz IF.

e9d021835a About to make a bunch of changes (really not all keyer related), so
committing for safety...

a039740466 Been experimenting with ways to clean up audio when USB is connected.
Believe it is likely a ground loop issue however.

57c97d9f98 Working with Raduino! High pitched whine in RX audio. Goes away when
USB unplugged.  Not immediate, so not a ground loop... seems to be
associated with one of my mixers...

4c2f6453f1 Moved the sketch into a subdir. Main folder should contain e.g.
schematics for the IOP setup.

f35653987f Updated to allow receiving (via serial) a mode command from the Raduino,
and then using that to set rigMode.  Note that it doesn't actually do
anything beyond that, at the moment, but I *think* this will allow PTT
events to be pressed in CW mode (as CW key down).

211d9ff9b4 (Temporarily?) resolved issue with no transmit output. It looks like
switching dacVolumes around from transmit to receive wasn't working as
expected.  Transmit audio through the DAC stayed muted.  If I need to
use that for smooth audio transitions, I'll need to do some more
research.

faa73e1330 Updating before switching back to previous commit, to see if it works.
This isn't transmiting.

f819e211da Significant reorganization of the code. Got rid of the audio classes,
just moved all the audio stuff into its own files.  Created a structure
for storing configuration data in... the intent is that it will be
stored to EEPROM (using EEPROMAnything).  It does compile now, but
haven't actually tried it out.  Notable learning points:  need to set
micGain AFTER selecting the mic input.  So lot of code now to take care
of trying to smoothly mute and unmute things.
