I read an article about a new Mobile User Objective System (MUOS) radio waveform that is supposed to be very useful for bridging beyond line-of-sight communications issues. [See article here: http://www.nationaldefensemagazine.org/articles/2017/8/11/army-one-step-closer-to-on-the-move-satellite-comms.%5D I am always somewhat skeptical of these systems however because most seem to have significant challenges:

1. SATCOM is great, but hard to get approval to use a frequency; even harder to get a dedicated frequency.

2. HF is great once it’s established, but few folks have the technical expertise to get this system up and running.

3. Different waveforms can require different radios, and carrying multiple radios can start to become cumbersome.

Anyone have any experience with MUOS who might be able to address availability, technical ease of use, or compatibility with current radio sets?
