Question on receiving calls

[steve352]

If my county FD is transmitting on a trunked system and is listed as digital can I listen to them. Here is what I see on here...
Marion County Fire/Rescue Talkgroups

DEC	HEX	Mode	Alpha Tag	Description	Tag
1113	459	DE	MCFR AllCall	Fire All-Call	Fire Dispatch
1100	44c	DE	MCFR North	Fire North Region Response	Fire-Tac
1101	44d	DE	MCFR South	Fire South Region Response	Fire-Tac
1102	44e	DE	MCFR Talk	Fire Talk Around	Fire-Talk
1103	44f	D	MCFR Primary	Fire Primary	Fire Dispatch
1104	450	D	MCFR Scene 1	Fire Scene 1	Fire-Tac
1105	451	D	MCFR Scene 2	Fire Scene 2	Fire-Tac

only on the non encrypted talk groups

The capital E in the Mode column indicates Encrypted.

No scanner can receive those.

annnndddd, you would need a digital scanner to hear digital signals.
what scanner are you using ?

The thread title shows 396XT

 

[FrensicPic]

The thread title shows 396XT

Also might depend on what the TRS is using: the 396XT is P25 phase I capable but NOT phase II.

 

[Enjoi19]

Looks like it is this system (Holy there are a lot of Marion county's in the USA!) Marion County Public Safety Trunking System, Ocala, Florida - Scanner Frequencies

Phase 1, so the 396XT is capable of recieving the talkgroups that are not encrypted. It's also 3 simulcast sites on this system, which the 396 may have difficulty properly decoding, depending on a variety of factors (See Simulcast Distortion for more)

 

[wtp]

doc, i missed that.
you did put a smile on my face, thank you.

So my bcd396xt can hear these correct

Thanks Doc

I followed the set up guide and when I hit scan it started to scan but says id search and below that it has NFM what did I do wrong????

 

[tvengr]

You can toggle between ID Search and ID Scan by pressing FUNC and then SCAN. If you see NFM, you are not detecting the control channel. That could be due to having the wrong frequency programmed or possibly simulcast distortion. You have 2 trunked systems, one for Marion County and the other for Ocala. The Marion County system has 3 sites. What control channel frequency did you enter and are you using programming software?

You are scanning a trunked system:

Marion County Public Safety Trunking System, Ocala, Florida

Marion County Public Safety Trunking System Profile

www.radioreference.com

When scanning that system type (trunked versus conventional), your scanner is monitoring the control channel, and looking for talkgroups. When you see ID Search, the scanner will stop on any active talkgroup it finds in the system, with the exception of any that you have locked out, or that are in a Group that is locked out. Encrypted talkgroups are skipped as well, though once in a while, the scanner may stop very briefly on an encrypted TGID, but as soon as it recognizes encryption in use, it will resume scanning.

If, instead, you see ID Scan, the scanner will only be looking for active talkgroups that you have programmed, and that are not locked out nor are they in a Group that is locked out.

On the 396XT, you can toggle between using ID Scan and ID Search by pressing the Function key, followed by the Scan key.

 

[Enjoi19]

Do you see signal bars showing up when scanning?

 

[MStep]

I prefer doing ID Search as opposed to ID Scan when monitoring a trunked system. On ID Scan, if, for example, you are downloading from the RR database, you will only hear those talkgroups which are already identified in the database. If you use ID Search, you will also pick up talkgrounds which are likely associated with the system, but which not have been ID'ed (or tagged), in addition to the ones which have already been identified.

For me, ID Search makes for much more interesting listening. Some scanners, notably the SDS series, have the ability to automatically search for talkgroups within a system that have not yet been identified, even when the unit is unattended.

yes its trunked

Just figured that one out just like my cell I am in a dead area 1 bar

As long as you see NFM on the display, you are not receiving the system.

Go to a better location and observe.

👍 Good luck!
