Reply To: what is needed to switch modes SM200C?

I appreciate it Andrew, but as expected, it was my fault. I won’t bore you with the details, but the way that the software was written (which was before my time), the vector of pointers to our sub-class of radios wasn’t getting freed properly. So even though the app was closing, none of our destructors were getting called, and it was keeping certain things running that we were only doing with the SH when in IQ streaming mode. Once I caught that and re-worked it, all seems good again.

So thank you for your help.
