Hi all,
I'd like to request two fairly high quality audio samples of some ProVoice as heard on a communications receiver (taken from a discriminator output would be perfect)... but there is a catch.
I need one recording to be from group that is KNOWN to be unencrypted digital ProVoice
and
I need one recording from a group that is KNOWN to be encrypted digital ProVoice.
If you can help with one or the other - or both! - I'd be very appreciative.
What I'm trying to do is determine if it is possible to distinguish unencrypted ProVoice from encrypted ProVoice just by ear. FYI it's quite easy to distinguish MA-Com's earlier Aegis encrypted vs. unencrypted - the difference is subtle but easy to pick once you know what to listen for.
The ProVoice samples that live on the 'net already lack any information as to wether they're encrypted or not.
