New non-government P25 Site in Sydney!
Posted: Sat Jan 29, 2011 4:45 am
I was somewhat stunned when i stumbled across this one at 4am this morning .... what sounded like a P25 control channel on 500.000Mhz
Did some research and came up with this
Airwave Solutions
500.0000 Tx ABC Tower Gore Hill 10K1F1D 50w - P25 control channel heard
500.2250 Tx ABC Tower Gore Hill 10K1F1D 50w
500.4375 Tx ABC Tower Gore Hill 10K1F1D 50w - P25 control channel heard
500.6500 Tx ABC Tower Gore Hill 10K1F1D 50w
500.8625 Tx ABC Tower Gore Hill 10K1F1D 50w
Not getting a great sounding signal for decode on Unitrunker despite good signal strength.
Might be better during the daytime
Every couple of minutes the control channel goes quiet for maybe 15 secs, either starts up again or hands it over to the other frequency for control channel duties for the duration, then hands it back again to the first frequency after a time
It is not a normal P25 control channel site like GPT
The control channel keeps stopping and moving which Unitrunker is not happy about as it keeps opening a new screen
APCO P25 00001-001 FDMA C4FM Modulation NAC000 Signal inverted
(Note: On 6/4/2011 the site ID shown on a Uniden 396 was 0002h-0101)
Licence was granted in August 2010 so it maybe still in development before going live
Would be interested to hear if anybody else is getting a cleaner decode on this site

PS The cynical side of me thinks that Airwave Solutions (part of the Macquarie Bank Group) is positioning itself for the longer term government P25 contracts in this country
They have already shown their hand in the UK over the TETRA rollout and at Sydney Airport ( = $$$$)
