Oxford

[Firebuff66]

Oxford FD & EMS have changed the output DPLs to PLs for those who listen with PL/DPL enabled

Oxford FD is the same frequency with a PL of 186.2
Oxford EMS is the same frequency with a PL of 162.2

Interesting they went from DPL to PL's, usually it's the opposite. I haven't noticed but I haven't picked up anything in a while, and that'd be why. Thanks!

Do you know if Fire 2 or Public Works has changed from DPL to PL's as well?

Looks like the mutual aid portables need to be reprogrammed...again!

New to scanning. Why do you normal go from pl to dpl? Also what’s the difference

 

[doctordialtone]

what’s the difference

PL Tone stands for Private Line Tone, DPL is Digital Private Line. It is a sub-frequency that filters out other radio user's transmissions on the same frequency in the area.

What are Tones? PL / CTCSS / DCS / CSQ

DPL / DCS Information

Is DPL tones better than PL tones?

If i had to guess I would say they went from single site to simulcast, If you simulcast with dpl it gives a chop chop chop sound but if you do PL or DPL in PL out it wont do that

Correct. They are on a simulcast system now, with the 3rd party equipment used to make that happen, a DPL was not compatible

3rd party because they didn't buy Moneyrola???? They are using DPL in and PL out.
Don't get me wrong I like Moneyrola but if you keep drinking the kool-aid all you will get is diabetes

they have motorola transmitters with 3rd party equipment making the simulcast, the equipment they used was not compatible with the output having a DPL

 

[nhfdcadet]

we got the whole story about it at the dispatch center the day they made the change

So you got the info 3rd party also

 

[nhfdcadet]

So you got the info 3rd party also

directly from the people who installed the system

Interesting. That makes sense. Woodbury's P25 has a 3 site simulcast and sometimes causes issues with my scanners due to the millisecond differences in receptions from the multiple repeaters I have in range. (I'm actually closer to Grassy Hill, but I get Great Hollow and Logue Farm area due to being in the hills shadow). DPL would be the same kinda and screw with the receivers decoding.

Public Works I verified is unchanged. D152. I picked them up today. They must not be on the new simulcast system.

I'm picking up the new PL's. They sound the same to be, not much improved reception, however being in Woodbury is the real problem, I'm sure it improved reception in town where it's meant to be heard. I'm lucky I can get it at all. I'm half tempted to set up a 3rd SDS scanner at work in Oxford to cover Troop A and Oxford since the reception from Woodbury is so low.

That would be cool. But would they let you do that?

No problem. I run ADS-B/UAT there already. Mind you i run them from a window, but building owner OK'd me throwing them on the roof if I found a safe way to do it as well... and have to mind the large AC units that would easily cause issues. It scares me a bit though because almost two years ago our building got hit by lightning and took out 6 AC units, along with some network equipment of mine. I'd have to do a solid grounding setup. I could easily grab KOXC air traffic as well given it's a quarter mile from the runway.
