While other scanners are taking off in their own direction,
the Pro 106 still rules!!
The great thing about it is-- if you put a channel on MANUAL,
you press FUNC + TUNE, and you have a freq waiting for a tone..
I have done this many times,
and found community repeaters and such...
This time, I did it to DHART.. 464.450-- dc-- 703
It gave me a DC of 723..
YES-- on 464.450
I have been listenning to it all week..
Not used much,
but it IS an active channel..
So---anyone care to ad on about this newly found channel?

I usually catch any DHART activity on the associated ambulance frequency 155.3400 for the area hospital DHART gets called to, or ends up going to, here in Central Vermont.
Example: local ambulance frequency here is 155.3400 but if DHART needs to go to Rutland Region Medical Ctr., I'll hear DHART on that 155.3400 frequency with a tone # 131.8.
If DHART needs to go to North Country Hospital in Newport, I'll hear DHART on that same frequency with tone# 114.8.

Not sure if this helps you at all though......

Sorry to say--nope...
It looks like we got ANOTHER mystery freq at hand..
I DO know it's NH based, by the 10 codes they use..
Possibly--Concord Hospital, transport?

DHART has/had a UHF Repeater for Manchester Ops, unsure if still licensed or now a Rental Freq, but the DPL was D703 for many years (most recently confirmed in April)

Hello,

According to this website, NH hospital base stations on the 155.340 MHz HEAR frequency use different tones.

Hello,

DHART maybe leasing/renting space on a commercial repeater. Other users would have a different tone on the repeater. Some radio systems have multiple "channels" that use the same frequency with different tones to separate communication within groups. Some radio systems use multiple repeaters on the same frequency to cover a wide area and use different tones to control which repeater is used.

My notes indicate confirmed DHART aviation assets using 155.325S, CTCSS 141.3, on 08/16/2015, in Chittenden County, Vermont.

FCC databases seem to be down at the moment, so I can't verify...DHART could have been talking to a local fire/EMS agency on their frequency and it may not be an actual DHART channel. The only user I have heard on that frequency in my area is Milton EMS, with a DCS tone of 606 (last noted in 2012).

I just heard 464.450 - dc 723 check in.
They had a hum in the background--so you could hear the automatic transmission on a vehicle shift..
As far as 155.340 goes, that's a simplex freq..
155.325 in Maine is also a simplex freq...
I'll leave it on tone search--maybe I'll get another tone..

The DPL 723 is active on the repeater used by DHART in Goffstown. Whether they or someone else uses it, I'm not sure. That repeater is licensed to, and has expired, for a radio shop. It could be a community repeater.

They are basicly associated with the Concord Hospital.
I've heard them say they were switching to the security channel..
And I'd say it's more of a -medical- repeater instead of community..

Concord Hospital is currently not using that frequency on their licensed sites and the tone is definitely on the same repeater as DHART. Could be something off site for Elliott. Hard to say. But I agree it's probably medical

OK, 1st off Danny, they are using NH state codes..
There IS a big difference in 10 codes between Me and NH..
2nd off, they have mentioned Concord Hospital many times--including security being mentioned..
3rd off, as much as everyone loves to think the FCC database has ALL of the current data,
they don't, or it is not publicized yet---yet..
I have had many people tell me --- this isn't listed, that isn't listed,
they are opperating on an expired license,,,,,,so on...
EXAMPLE--- we have 2 LTR systems located on top of Mt, Aggie...
There is no mention of them at all in the FCC database..
1 system is an active concrete co,
and the other just lets out the bursts every 10 seconds..
So-----like I said, and Mr. Marcel agree's to------- who is on that DPL?
