Wow, well done!

Thanks Harry, but as you said, something seems to be out by one?

I can 100% guarantee that TG 10644 is Ulladulla as it's my local talkgroup and I'm sure it has been referred to many times as "channel 44" (I think I may still have a recording of such from the big storms a while ago)?

Also, somebody here has already confirmed that channels 45 & 46 are the SCADA comms talkgroups?

Is there any chance that your list has an extra entry in there somewhere?

Andrew

EDIT: Just had a thought (and I'm only guessing here but)... all the above would line up if their talkgroup allocation started at 10600 instead of 10601?

Although this would be a bit unconventional as all other agency's allocations appear to start at xxxx1 (with the exception of RFS but I assume that's because they had to do a radio profile upgrade very early on in the peace)?

10645 gets used alot by Techs at Castle Hill, havent seen 10646 at all.

I noticed that out by one too ... suspect that one of the D19 ... D22 maybe a standalone P25 frequency rather than a GRN channel

D22 BYLNG

Thanks Col,

So it's probably safe to assume that "D50 BYLNG A" would also be a conventional channel?

Any idea what the abbreviation represents?

Yeah its Bylong, NE of Mudgee.
Endevour have PMR allocations in that area, due to no GRN coverage in that area.

hope this is of help

D22 BYLNG is actually D22 BYLNG D a slight correction, sorry guys and 50 BYLNG A are both scan channels. I had a look at the display again and noticed a scan symbol. I then checked to see what channels are scanned and it was

D22 BYLNG D and DIE_DIR1

D50 BYLNG A and DIE_DIR2

If we remove D22 this will then allow the talkgroup names to line up with what has been worked out already.

Thanks
