I have always had half an eye on SETI. Fascinated at the disjuncture between those determined to find other non-Earth intelligence in deepest space while I can watch the antics of non-Earth intelligence in the skies above my head. Trust me people, anyone can see 'anomalous non-surface structures' simply by putting in a few hours a week watching the sky. Not glancing up now and again but concentrating and watching and learning what should and should not be there. The anomalies are not subtle either. Once you have seen these objects you will go on to see ever more of them.

The question for me is how are they managing comms. There must be a million ways of transmitting different kinds of signals for different purposes and over different ranges. Are the locally active ETs able to carry out all of their business telepathically?

Famously Margaret Thatcher claimed that there was no way for her to have ordered the submarine attack on the General Belgrano during the Falklands War as she could not talk to a submarine in the ocean depths off of the tip of South America. I later learned from a Telecoms expert that they had a system of sending long waves through the Earth's crust to reach any point on earth designed specifically to reach submarines in distant waters.

I mention this to highlight that any kind of unexpected system may be at work if they need to keep in touch as we do. Do they use anything that we could detect physically? I mean they could be mucking about with light frequencies reflected from foliage and relayed via space base decoder/encoder satellites, or embedding comms inside our comms in the way you can hide messages in Graphics Files.

We do pick up some of their activity on Radar although some of our own craft are now able to elude radar. Just wondering if they do anything, not necessarily telecoms, with enough physicality for our scientists to detect?

The Military have had ground radio since the time of Tesla and Marconi. They can transmit signals to submarines.

However, the Military don't keep 'Operational Staff' 'in-the-loop' about the State or Capabilities of their Communication Facilities.

"Operational Staff" includes the range from the Prime Minister down to Sailors on the Submarines.

The actual Radio Bandwidth might be low, but messages can be transmitted.

If you go onto most Submarines, you will find that the Communications Room is "Top Secret" and they don't even want anyone knowing what type of equipment is even inside the room. Not even the Submarine Captain is usually given Military Hierarchy over the Communications Officer.

So that is a small insight into how the system works.

TTE is a related Communication system, that you can read about here :

I think Aliens can use dimensional technology for communication, if they developed technologies to travel non linear of our time dimension , then in order to have linear communication they should have tech which dont broadcast anything it rather open dimension and send data stream, i guess in order to pickup such transmission somebody should have satellites which use special device ( back engineered or repurposed from alien ships) which can "sense" minor violations of the time dimension around Earth and some how lock into it and then on Earth some black side facility modulate the frequency and then can extract from that dimension transmission.
Of course its only wild guess, but even if it's possible what if the transmission is encrypted and can only deciphered on alien hardware, so many questions......
