Rob French 6581a5f2a4 Insanely, this also compiles.
Numerous changes updating modes, rig, config, everything... don't think
this ones gonna work first time through...

Rob French 66d1924685 Added speech compressor. Works.
Added some menu code.  But this needs to be redesigned.  Commented out.
Work this on a branch.

Rob French c5a7592346 Added equalizer to smooth out RX audio passband. 2020-06-05 12:11:38 -05:00
Rob French 519a208508 Fixes to get it running, working for the most part (currently using DGU
mode on 40 meter FT8, so it can't be all bad).  Filters added, although
not currently selectable (til I get the rotary encoder added).

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

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

Rob French 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.

Rob French 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.

Rob French 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.

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

Rob French 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...

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