I like the compactness, and since it seems to be North American gear I'm wondering if additional gear like an HD Radio (IBOC) modulator-injector such as a Nautel HD MultiCast+ could be part of the chain? I wish there was progress on an open source IBOC exporter but it doesn't seem to be a thing and its waaay outside of my capabilities.
HD Radio is still (annoyingly) covered by patents in a way that open source efforts like nrsc5 still can't be integrated into any OSS radio tooling for fear of litigation.
And from my own IANAL research, it seems iffy whether the initial set of patents which is expiring soon are the ones that will open it up... or if any of the many follow up set of patents can keep it out of easy reverse-engineered access :(
