  Very long distance radio link with relatively modest power at a super high frequency. Normally you'd not get much better than line-of-sight with a setup like that. So you have to work DX using satellite or EME.

    That last sentence means that if you want to contact distant stations, you have to connect through satellite relays or by bouncing radio signals from Earth to the Moon and back to Earth (EME)

    It helps that FT8 is amazing. I can easily contact Japan from Massachusetts using a modest "cobweb" antenna (on my side) and a large beam antenna (Japan side). 100 W, but this is on shortwave which can bounce off the ionosphere. WSJT-X is the software by Joe Taylor, who is a Nobel Laureate. The signal processing part of the program is written in Fortran.

      Yea, ft8 is pretty cool. I've been able to work Europe on 6m during the summer E season (and hear Japan) along with some amazing dx contacts under marginal conditions on HF with it just using a simple dipole antenna.

    It's an ultra high frequency. Super high frequencies are from 3 GHz to 30 GHz.
