I believe basic encryption is no more than voice inversion. I have several users on DMR systems that are using "encryption" which shows no "E" on my Whistlers.Ok, if it can be voice inversion, because the "E" does not appear.
In digital system there is also the voice inversion.
i did not know.
Unlikely on a digital transmission. The low bit rate speech only encoding used only encodes speech well, not inverted speech.Could be voice inversion, not encryption.
Under test conditions, I can get it to show for Conventional NXDN, but only when the channel has been stored as a memory channel. Oddly it doesn't show when the same transmission is detected/decode using Limit Search. Whistler have stated to me they 'don’t handle any manufacturer-specific encryption' s don't expect to see E on DMR then.Unlikely on a digital transmission. The low bit rate speech only encoding used only encodes speech well, not inverted speech.
Has anyone actually seen the E ?
Your not seeing the E because it is probably a TDMA communication your are hearing the encryption on whether it be phase 2 p25 or DMR. The encryption packets are sent over the air differently due to there being two slots and not just a single transmission on the frequency. Basically when monitoring a TDMA transmission the scanner doesn't know know that it is encrypted because it never recieved the encryption header in the data stream. Well it recieved it but does not know how to interpret it so the little E will not show up and it will pass the encrypted audio. Trust me it's not voice inversion if it's digital it's a keyed encryption code. The scanner just doesn't understand that the transmission is encrypted. Both uniden and whistler model scanners are effected by this issue.Yep!
Yeah but I doubt he would try and decode tetra with a trx-2. I mean it was never advertised to decode tetra and I very much doubt it does. I thinks he listening to DMR. Could be wrong though. Wouldn't be the first time [emoji3]The post has the location listed as Spain !
Perhaps it's tetra or other mode. Very little info
found for that country...
