Trunking TG-Scan or Monitor

[mdsxfire]

I just set up a system (Baltimore city) I have the wildcard TG (FFFF) so I pick up all traffic on the system. Does it matter if I choose Trunking TG-Scan or minitor if I use the wild card TG

You have that slightly confused FFFF would not be considered tg wildcard. The tg monitor is the same as id search or wildcard. tg scan will only scan your added Tgids. Using FF just sets the receiver to search the system parameters not tgids.

Actually, unless it has recently changed, a "wildcard talkgroup" of FFFF (65535) functions more or less the same as using TG-Monitor - you'll here any/all active talkgroups on the current system/site

Actually if you just use FFFF where its supposed to go you will have nothing to scan! You still have to create a zone and set up a knob position, and set as either tg monitor or tg scan! You cannot just program FFFF and the whole system be wildcard scanning.

Yup - that's what he said...

No - it does not when using the wildcard talkgroup.

Ffff is not what you set up to id search.

A year ago, (several firmwares ago) There was not an option in the drop down menu for TG-Monitor.
Unication gave us a way to monitor TG on a system by adding a TG of FFFFF which back in the day was the wild card.
I believe it still works. However if your a new user that info maybe lost to you as it was not needed since we now have a menu tab for TG-Monitor which is the new form of wildcard.
You still have put a TG in the scan list but it can be anything as its more of a place holder.

Oh ok that makes sense i have only had mine a month but i did program it myself. Knew i wasnt loosing my mind..

Minor correction - the "wildcard talkgroup" is FFFF (not FFFFF)... FFFF is 65535 decimal.

Both options work - add a "wildcard group" of 65535 (FFFF) to you TG-Scan knob -or- create (or change) a zone to TG-Monitor -- same result.

For reference - wildcards:

WACN - FFFFF
SysID - FFF
RFSS - FF
Site - FF
Group - FFFF

So, if I were to enter ALL the primary and alternate control channels of a particular zone of VIPER on one knob position and add the wildcard "FF" for the site, I could actually travel around that area of the state and the G5 would find the strongest signal (or closest) site and monitor it?

And then when there was a stronger signal present, it would lock on to it instead?

How does encrypted talk groups affect a wildcard site search?

For the most part - yes.

The G5 will look through the list of frequencies you've provided and find one that meets/exceeds signal quality (I think probably the first one it finds - I do not think it will check all and then say "this one is the best"). It will hold/stay on that CC until the signal quality drops. Then, it will start looking for another CC. This doesn't necessarily mean that it will be the "strongest" of the CC on the frequencies you've programmed nor necessarily the closest (you can control which site the G5 tries to use but that is programming that is the complete the opposite of what you have proposed).

In your proposed programming, as long as the current site signal quality is sufficient, the G5 will not start looking for another CC on another frequency.

Alternatively - rather than entering all of the known CC frequencies, you could use "Full Spectrum Scan" with a limited frequency range. However, that will likely be a bit slower when searching for a CC frequency than providing a specific list of frequencies.

Keep in mind that the talkgroups that are active on site 2/78 will almost certainly be completely different than those on site 2/15 so how you program the talkgroups on a given knob will be critical.

How does encrypted talk groups affect a wildcard site search?

Wildcard for site ("FF") has nothing to do with which talkgroups you'll hear. Regardless of if you use "FF" for the site or the actual known/expected value, what the radio stops on and you hear will be based on how you've programmed your (talk)groups - and - which talkgroups are actually in use/active on any given site.

Also - totally independent of how the sites and frequencies are programmed, encrypted talkgroups will be heard as noise if you program a knob to include any of these:

• use TG-Scan with a known specific talkgroup that is fully or partially encrypted
• use TG-Scan with a wildcard talkgroup of 65535 (FFFF)
• use TG-Monitor

I use this on Viper when I travel outside my area. Set Site to FF and I use Full Spectrum Scan. And then use TG Monitor.

 

[CFP387]

I only have SHP and county Fire & EMS dispatch TG's in the VIPER knob position. I wouldn't be doing a "full spectrum scan" so I wouldn't be hearing every talk group on any particular site. My idea was to program every sites primary and alternate CC in a particular VIPER zone and, while traveling around, it would roam tower to tower and I would hear only the those SHP, Fire and EMS TG's depending on my location and their affiliation with that site.

 

[troymail]

Full spectrum scan relates only to site frequencies and has little/nothing really to do with talkgroups.

Many times when I travel, I'll program a knob for each county that I'm traveling through. This usually includes the site(s) to be scanned as well as which talkgroups I expect/want to monitor in that area. Then, I just turn the knob.

There are many different approaches.
