Hello Tony,
the sBitx RPi code will be of very limited use for the RS-HFIQ, as the RS-HFIQ delivers I/Q-audio signals and particularly expects I/Q-audio signals for the TX part.
The sBitx software processes just single channel (no I/Q) audio signals.
Instead you can use one of the available SDR/SDT software packages, to make the RS-HFIQ a fully functional transceiver.
I am running Quisk () on the Raspberry Pi with this overall architecture
For the bi-directional Audio stereo (I/Q-signals !) interfaces to the RS-HFIQ I am using either a Behringer UFO202 or UCA202 interface, which is in the €25 price range.
To interface to the microphone and the headset, I am using an additional low-cost USB Audio interface, which will be in the €5-15 price range.
I have been lucky, to find an interface which has 2 3.5mm connectors for the microphone and the headset. In addition it has a 4-pole 3.5mm connector for a combined smartphone headset.
For the display you can either use a standard HDMI monitor or you buy e.g. a 7" HDMI TFT-display with touch, that can be connected and power supplied through the raspberry.
I am using a display with a 1024*600 physical resolution, but which also accepts a full HD signal via HDMI.
With such a display, you would be able to operate Quisk, but it might be a bit challenging, as Quisk is not touch optimized.
I would recommend that you connect a mouse to the Raspberry via Bluetooth and with that you will be able to use the mouse wheel as the tuning knob.
For Quisk you will need a hardware configuration file "hardware_usbserial.py" for the RS-HFIQ, which you can find e.g. .
You will have to configure the audio interface in Quisk appropriately (in the UFO202 and UCA202 one audio channel is one cycle behind the other, which must be configured in Quisk) and then everything will work nicely.
I am using this configuration for quite some time now.
The nice thing is, that you can also fully remotely operate the Raspberry with a RealVNC client, that can even run on your smartphone or tablet.
Audio can be transported through Mumble. You can also run in parallel to Quisk WSJT-X on the Raspberry.
There are a lot o things, that can be done with this configuration and if you get over the initial hump, you will have learned a lot about Linux and its sound systems, hi.
It could finally look like this (without the 7" display but with a USB-C PD powerbank supplying the 12V for the RS-HFIQ and 5V for the Raspberry Pi and Audio and a passive USB hub):
Feel free to contact me, if you have any configuration questions.
