I am in Vance County NC.. and I keep getting noise with a talk group id of i1814. I am not sure what the "i" is for.
Is anyone familiar with this id?
Assuming this is on your BCD436HP, it sounds like it's what is called a I-Call or "private call" (1 radio calling to another radio vs. a "group" call on a talkgroup). I'm assuming it's a digital system and one of two things are happening:
1. the call is encryped and you're just hearing the encrypted data noise, or
2. you're hearing improperly decoded digital voice
Without more details, it's hard to really say for sure.
For #2 above - since getting my 536, I've heard some digital (unencrypted) I-Calls that were decoding in a fairly "sloppy" way... meaning, there was voice at times but typically when one user stopped talking and the other started, the radio was struggling to decode the start of the voice and eventually settled down - but that happened every time the "other" end / user started talking. I'd hear the digital noise before voice ("motorboating").
I believe the reasons for this are that the radio wasn't told in advance that the I-Call is going to be analog or digital so it has to determine this "as it receives" - probably treating it as analog at first and then switching to digital decode when it "figures it out".
This is also probably the reason some of us are seeing a delay in the start of digital voice (digital decode) on regular digital talkgroups during normal scanning.
