It would be incredibly helpful to rapidly relay text, especially if transmissions are brief.
Thank you again for the info!
Might also refer to the numbers station(s). They are an interesting subject. Good communication with large amounts of text would be a challenge in the apocalypse. I like the concept of Citizen Z from the tv show Z Nation.
From wiki:
A numbers station is a category of shortwave radio station characterized by broadcasts of formatted numbers, addressed to intelligence officers operating in foreign countries.[1] Most identified stations use speech synthesis to vocalize numbers, although digital modes, such as Phase-shift keying and Frequency-shift keying as well as Morse code transmissions are not uncommon. Most stations have set time schedules, or schedule patterns, however other stations appear to be broadcast at random times. Stations may or may not have set frequencies in the HF band.[2]
The first known use of numbers stations was during World War I, and the first possible listener was Archduke Anton of Austria.[3] The numbers were transmitted in Morse code. Numbers Stations operated mainly during the Cold War, yet many continue to operate and some have even switched operators[4] The Czech Ministry of Interior and the Swedish Security Service have both acknowledged the use of numbers stations by Czechoslovakia for espionage,[5][6][7] with declassified documents proving the same. With a few exceptions,[8] no QSL responses have been received from numbers stations by shortwave listeners who sent reception reports to said stations, which is the expected behavior of a non-clandestine station.[
