I doubt that a digital modem signal on 121.5 or 243.0 would sound much like the swept analog tone of an ELT.


We're not talking about strictly ELT signals. I should have made that clearer in my previous post. These are international aviation emergency frequencies that aren't restricted to ELTs. Anyone who is experiencing an aviation emergency can transmit on these frequencies using whatever kind of modulation they want....even if they want to mimic an ELT and whistle. Although transmitting their last known coordinates might be a tad more useful.

Why not? Either would still break the squelch on an AM receiver. AM receivers don't discriminate much. That is one of their weaknesses.


Try holding an AM radio up next to your computer.
