I would love to see this implemented into gqrx as the application is a native Linux program and I would like to have a good panadapter for my IC-706MK2G which doesn't have the best filtering. There are ways to do the same with HPSDR but since it's not a Linux application I'm reluctant to do so.
QProcess rigas;
rigas.startDetached(
"rigctl"
, QStringList() <<
"-m 2"
<<
"F"
<< QString::number(freq));
