Configuring WSJT-X on Ubuntu for an Icom IC-7200

I’ve been trying to configure WSJT-X so I can run FT8 and WSPR for quite a while now. I finally tracked the problem to my Macbook which is introducing noise to the radio (could be the USB to USB-C adapter) and WSPR-X also crashes a lot during transmission. After switching to an antique Dell Latitude D520 from 2006, my signal on 40m (7.038600 MHz) is being received.

Here is the database output from wsprnet.org, of unique spots sorted by distance owith transmit power from 5-100 W. I was able to hit the US, Canada, Japan, Western Australia, etc with 100 W. This was with an end-fed half wave antenna with part of the antenna inside the house!

Installation of WSJT-X was done by:

<code>sudo add-apt-repository -y ppa:ki7mt/wsjtx-next
sudo apt-get update
sudo apt-get install wsjtx
sudo usermod -a -G dialout $USER # then need to logout and login again
</code>

Check using http://time.is that your clock is accurate (it should be automatically synced in Ubuntu).

In WSJT-X, the Radio settings are:

<code>Serial Port: /dev/ttyUSB0 (baud rate: 9600, Data: 8, Stop Bits: 2, Handshake: default)
PTT method: CAT. Mode: USB, Split operation: Rig
</code>

and the Audio settings need to be set to alsa_input.usb-Burr-Brown_from_TI_USB_audio_CODEC-00-CODEC.analog-stereo with the Pwr slider all the way to the top.

On the radio:

<code>Data: oF, MoD: U, D-MoD: MA, USB LVL: 80
</code>

(13/10/2018 - Jimmy Capizzi on the 7200 Owners and Fans Facebook Group suggested to set the d-mod to usb and the regular mod to microphone. That way it’s only one menu option to work voice ssb.)

Here is the result (in reverse chronological order) as I increased the power. Interesting that, with my current antenna (a end-fed half wave), I didn’t make it out of Australia with less than 50 W.
