not sure if there is a more precise term. Basically, imagine a gadget that listens to one-way packet switched AM radio transmission. Ideally it should listen on a range of frequencies, like a “scanner”, and either save into memory or print out any text transmissions it gets. So if emergency transmissions were transmitted and received like this there wouldn’t have been the whole issue of waiting for the transmission, scanning frequencies manually, trying to understand garbled speech on a poor channel, taking notes while under stress and so on. Scanner would grab all transmissions automatically, even when people are busy, whereas the more compact nature of textual data would have allowed more redundant transmission that is less likely to get drowned out by noise.
Are there similar systems on the market already for some purpose, not necessarily emergency one?
Is there any sort of standard for emergency AM transmissions in the first place? In the sense that if there is one standard, maybe it could change towards better systems, whether the above-described or other improvements on the state of the art as of 1930.
