I know it is hard to keep track of all the early experiments folks have done with different radios. I have worked with the IC-7000 since the first BETA's and have sent you my setup and settings files multiple times. I have never solved the problems I see here with the IC-7000.
Before you ask: The IC-7000 works properly with other sound sources. I can connect a USB SignaLink to the same RPi as DRAWS is mounted on, connect the SLUSB to the IC-7000, adjust the output and input levels, and run an fldigi or wsjt-x QSO at 30 - 40 W with minimal ALC reading.
What I have done so far several times:
Each time I test the DRAWS hat, I start with your suggested settings from the GitHub files. The "setalsa-ic7000.sh" script sets them like the attached JPG and ALSA setting output files show. I reset to these levels each after making any unsuccessful test adjustments so I start back at the same point each time.
Please note: the settings work fine when the IC-7000 is in FM mode for packet or for testing a modulated carrier *on any band*. Xastir/Direwolf therefore works for me.
In USB or LSB mode *on any band*, DRAWS and the IC-7000 will not "play nicely" with each other. At the settings in the attached files, there is no detectable tone when I listen on another receiver (but there is a lot of digital hash noise). I can "force" the rig output up to about a watt by jacking up the DRAWS analog and digital gains to absurdly high levels (+12 Analog +20 Digital). At these levels I can hear a reasonable sounding tone on the second receiver which can be decoded... but it is very low power.
FLDIGI and WSJT-X are basically pretty unusable at these low power levels. I have attempted to use ALSAmixer and/or John's control panel to find the correct drive levels without success.
My conclusions: using DRAWS, fldigi and wsjt-x will not transmit at normal power levels in sideband on the IC-7000. The rig will transmit at normal power levels in FM with the DRAWS hat.
I have also tested my FT 817 which works in DIG mode with the appropriate settings using either DRAWS or the SignaLink - but that is not the "target radio" in my application. I need a 100W HF class field radio with 2M and 440...
Happy to look at this again methodically - just let me know what files to send you.
