15 KW seems low for a serious SW broadcaster. But maybe not inappropriate for a HFT data broadcast using log periodic beams for a point to point circuit.
Are DRM transmissions low enough latency to be consistent with high frequency trading requirements?
I’ve wondered what part of the FCC rules they were going to apply for a license under. They certainly aren’t aeronautical or maritime and an experimental license no longer worked once they became operational. Maybe this is their path.
I suspect 15 kW is enough with directional antennas on each end of the circuit. I suspect they should be able to transmit their data payload over DRM without too much of an additional delay, they probably have figured that part out already.
There used to be allocations for fixed services like the old point to point telephone services, but perhaps licensing for that no longer exists? You'd think if there was something else they could use, they would have done that, before going down the SWBC/DRM route.
Honestly, if this keeps them out of the 43m/utility/other fun bands, fine with me.
