700Mhz Medevac config

SDS-100...
Hello all, I have the 700Mhz Medevac frequencies programmed in but have never heard anything. In Sentinel, do I have to set the audio type to digital, and select a NAC? What is the NAC? I don't see 293 in the drop-down.

Thank you.

Mike

If you do not see you NAC, though I'm sure it is in there as 293 is a default, common, NAC, select Digital Code Search and it will search for your NAC.

It's not in there in the drop-down. Don't I have to receive a transmission in order to have the scanner find the NAC?

One of the 700 air to ground p25 frequencies is patched to the syscom talkgoup on Maryland First System and also low band 44.740.

 

[baybum]

Which one?
But that still leaves the issue I have of properly configuring the 700 channels.

I've never heard much of anything on the 700 Medevac freqs, you could try these also...

ExpressCare 1 (Martin State Airport) *	453.425​	FM	CTCSS/DCS Search

I believe these are what you are looking for, at the bottom under 700 air-to-ground:

National Interoperability (United States) Scanner Frequencies and Radio Frequency Reference

Scanner Frequencies and Radio Frequency Reference for National Interoperability (United States)

I never hear MD medevac on these but they are supposedly used (patched).

 

[baybum]

No, I'm programming the Maryland Medevac stuff.

If you look at what I posted you will see the 700MHz channels are the same. These are really NIFOG 700 A-G frequencies.

OK, Also, which one is patched to FIRST?

Maryland FIRST 700mhz TRS

Well that’s a first, seeing two barracks from different counties patched together.

I think it's Air60 they are on, but if you enter all and scan you will pickup the one that is used.

Don't expect to pickup much tonight with weather and icing I doubt the helos can operate in this weather.

I have the 700's programmed in their own favorites list.
And have this in my "FIRST MED" favorites list .... Is this all I need?

For helo medevac I would really only load the last two talkgroups Helimed 7648 and Syscom 7640.
