Up here in the north of Scotland the various council water and drainage departments often had to send data from remote data loggers (high tech stuff in the early 80s). Some of them would transmit a little ping of data every few seconds and if it heard a reply it would send several bursts of data quickly, using meteor scatter[1] to get it back to the receiving station hundreds of miles away. All gone now, it's all 4G. A few hours drive north of me is Mormond Hill, formerly the site of one part of the North Atlantic Radio System[2]. This used tropospheric scattering and huge dish aerials to communicate radar data down to RAF Fylingdales. There's not much up there now. There were various BT microwave links for offshore oil installations and assorted UHF and VHF links up, but the masts are pretty bare now.
