Has Islip Town switched to digital on their UHF frequencies? I'm not hearing analog transmissions on their frequencies anymore (unless I'm not listening long enough).

For what it's worth, their UHF licese (WEC745) only shows authorization for FM modulation (20K0F3E).

Their TG on the SCPD 800 system is actively being used.

It doesn't sound like it is conventional P25 to me. I'll have to hook it through DSDDecode and possibly DRM Decode to see what type of modulation they are using.

I'm going to guess TRBO at this time.

Sorry Dave, I didn't have a chance to do this yet. I've been busy programming scanner and pagers pretty much all week for the last few months. Business has been good

Dave,
I threw DSD+ on for a few, and this is what I found so far. I need more time to monitor this.

0471.3375 Islip Town F1 - DMR - CC10
0471.3625 Islip Town F2 - No Rx
0470.3625 Islip Town F3 - DMR - CC06
0471.3875 Islip Town F4 - No Rx
0470.9125 Islip Town OEM 1 - DMR - CC05

It looks like 471.3375 is a Capacity Plus trunk site.  I'm looking at 2 talk group so far (TG 10, TG 50)

Was very, very close to a brand new marked Town Of Islip Public Safety car today and all he had was an 800mhz antenna. He also had a computer in the car. I did not see an 800mhz license for islip.

Nor did I see any uhf antenna on the car. It does look like they transitioned to dmr though their license does not reflect it.

Been off this board for awhile, but check it every now and then....From my understanding the Fire Marshals have switched to a Digital system and Public Safety/Park Rangers are on the County's 800 system.

Re: Town of Islip UHF
Dave3825us, Wed Feb 10 2016, 02:07am

The rangers and fire marshals are on the 800 system. I have not heard public safety or code enforcement on that system.

The freqs listed for islip are dmr. Their licenses do not reflect a digital emission. But they seem to be dmr cap+ ras.

I believe I might be ready to make a submission for this system (even tho its enc) but wanted to know if someone who understands cap+ could run the following thru dsdplus to confirm I did this right..

network file entry

Cap+, 9999, "Town of Islip"


freq file entry

; Cap+ Town of Islip

Cap+, 9999, 1, 1, 471.3625, 471.3625, 0
Cap+, 9999, 1, 3, 470.3625, 470.3625, 0
Cap+, 9999, 1, 5, 471.3375, 471.3375, 0
Cap+, 9999, 1, 7, 470.9125, 470.9125, 0
Cap+, 9999, 1, 9, 471.3875, 471.3875, 0

site file entry

Cap+, 9999, 1 "site 1 Islip"

from event log
2019/08/26 08:08:18 Freq=470.912500 DCC=6 RAS 470.912500 is first Cap+ repeater (Ch1 and Ch2)
