Do you have each of the two devices working separately?
Is there some conflict between the two devices when used together?

I have not yet connected everything together. I was asking in case others had encountered any issues. I will provide an update after everything is connected and let the forum know.
Thank you.

I have the SDRPLAY, MFJ-1708B-SDR switch and my Yeasu FT-920 HF radio setup. It works really well.
The video below helped with connecting the Tx Gnd from the radio to the Control port on the MFJ-1708B-SDR

Since MFJ has gone out of business I would look at the following option
