Signaling, NON-MDC on Conventional Analog channels

Post by libuff »

heres the sitation, a municipality i work in has XTS-3500R UHF2 Type 3 portables... the flash code is 500001-000000-8, decodes to:

Q806/G806 IMBE / APCO-25 Digital Operation
H14/G114 Digital ID Display
H35/G48 Conventional Operation

however, they are operating on some frequencies with MDC1200, and some with another type of signaling. all channels are in Analog, i believe they are still working out the ASTRO kinks...

for the frequencies that are NOT using MDC1200, there is a quick data burst at the beginning and end of the transmission, it is DEFINATELY NOT MDC. the portable is decoding MDC id's as ID: 6733 (for example).... when the portable decodes on the non-MDC identififed channels, it shows ID: 30006733 (for example)

so you guniesses out there... What signaling are they using?

Digital Soft ID is my guess.

Sounds like it maybe is the "Tactical Public Safety" Signalling.....

What FDNY uses on their XTS3500....

I am pretty sure it transmits voice in analog and then the ID is digital.

Here is more info at this link - http://batboard.batlabs.com/viewtopic.php?t=1857

I just recorded the TPS Signalling but am unable to figure out how to get the .wav file on here.
