Program Sudbury PD as a P25 One Frequency Trunked system as noted and use the frequency 852.9125. Then go back and edit P25 NAC Option to set the NAC to 443.
Actually, unless you know for sure that Sudbury is using talkgroups on their digital frequency, it's not necessary to enter as a One Frequency Trunked System.
Hello,
Thanks for all the previous help.
Not too sharp with this, so please bear with me.
Have a Home Patrol-1
Trying to receive my local P.D.
Live in Sudbury, Mass. (Middlesex County)
Apparently our P.D. is now P25
I went to Sentinel to put P25 in the Mode column
for it, but there is no P25 option.
Only:
Auto
AM
NFM
FM
I selected Auto, and downloaded to the HP-1, but hear nothing on
the local PD channel (852.9125)
Why no P25 option ?
*Should I be using Auto for mode, or...?
*Also I set IT to NAC Search. What is this, please ?
Is this correct for what I want to monitor ?
Any thoughts would be appreciated.
Thanks,
Bob
In Sentinel, I presume that you already have a conventional system for Sudbury, perhaps as part of one for the various municipalities in Middlesex County. If so, you probably have a frequency already entered for Sudbury. If they've changed frequencies when they went digital, then edit the entry for Sudbury (probably entered as a Department within a conventional system covering the county) to update the frequency.
Once you've updated the frequency field to the new value, choose NFM for the Modulation field. Then, in field for
Audio Option, make that field say
Digital, instead of
Analog or
Search. On the same window that pops up, when you change to Digital, you'll see a column (in Sentinel) labeled as Digital Option. Select the bullet point next to
P25 NAC. Then, in the field next to P25 NAC, choose the NAC value of 443. Then, be sure & save your changes before exiting the editor & writing the updated information to your scanner.
If you simply want to add the frequency, without replacing whatever the old channel was, then, in Sentinel, edit your Middlesex County conventional system. Click on the system name in your Favorites list, then, in the list of Departments that are displayed, select the one for Sudbury. After you select Sudbury, you'll see the currently programmed channels in the right side window. Click on the large green plus sign at the top of the screen in the right side window. That adds a channel.
On the new channel line, enter the text tag you want, then the frequency in the labeled field. Then, select NFM for Modulation, and Digital, as noted above, and also set the P25 NAC value.
Note that if you were going to simply create a new Favorites list in Sentinel, you could click on
US in the left side window, then scroll down and select your state, Massachusetts. Under the state, scroll down till you find your county, Middlesex.
Under Middlesex, select the County Systems folder, clicking on the "+" (plus sign) to expand the folder comments. The item labeled as simply Middlesex contains all the conventional systems and frequencies used by the various agencies and municipalities in your county. Using the Favorites list editor, you could then trim or rearrange the systems as you wish. (Note that this would basically create the same type of system I mentioned at the top of this post, one with the conventional frequencies in use in your county.)
