Hi Josh - thanks for your help. from ./python/bindings/hermesNB_python.cc:
void bind_hermesNB(py::module& m) { using hermesNB = ::gr::hpsdr::hermesNB; py::class_<hermesNB, gr::block, gr::basic_block, std::shared_ptr<hermesNB>>(m, "hermesNB", D(hermesNB)) .def(py::init(&hermesNB::make), py::arg("RxFreq0"), ... long list of arguments...
