Hello, have a new BCD996P2 and have been able to create conventional system with two channels using freescan and able to receive transmissions.
However, we are trying to create a new Trunk system and have inputted the data but am unable to receive the programmed talk group of 701. We have a 14-channel (one control) phase 1 Motorola system and only need to receive one talk group. We will be going to phase II simulcast Motorola P25 trunk system in a year or so. Not sure if i should select phase 1 or 2,,, both should be compatible to TDMA and FDMA right?

Can't say for sure since you didn't provide the RRDB link to the system in question. However regarding talkgroup mode:
Mode D = FDMA
Mode T = TDMA

If you're seeing primarily mode T talkgroups then the system can only be Phase-II. Mode D can exist in either Phase-I or Phase-II. Consult the RRDB to determine what type any given system is

Welcome to the forums!

The system type that you should set in FreeSCAN is “Digital XT. That’s the correct type, for the P2 scanners for both P25 Phase I as well as P25 Phase II. Other than any changes to the control channels (like changing to a different frequency or deleting a frequency), no other change to the site would be needed when the system upgrades from Phase I to Phase II.

Hello sorry for not knowing too much aboour programming kinda new at scanners. I was able to import the talkgoups from RR database, however i only needed one LOB FD-701 so others were deleted. I noticed you mentioned control channel, is there place in the freescan program to tag a frequency to be a control channel? Thank you again.

not sure if this helps,,,, the system has 14 FDMA channels and has a primary and 3 secondaries control channels (not used unless primary goes down). I have deleted all but the primary control channel but still unable to receive the talk group transmission. In addition, i noticed when monitoring the control channel in Hold mode the scanner appears to be squelched as there is no control channel data, I did notice the scanner does have 5 receive signal strength bars.

What system are you trying to set up? Provide a link to it in the RR database.

1) Motorola type I is not the same as P25 phase 1
2) very doubtful you have a Motorola type I system
When imported via FreeSCAN, FreeSCAN is not using the correct system type.
As imported:

The MOT2 prefix before the system name is how it would treat it.

The Mot Type II/P25 would be the system type that would have worked in the "T" series scanners, 396T & 996T.
FreeSCAN does not give you the Digital XT system type when viewing the imported site settings. You only see the choices below.

Go back to the initial System screen.

There, you can change it to the Digital XT setting.

Once you make the change at the system level, then the site can be corrected to the Digital XT setting.

Note that the system prefix changed from (MOT2) to (P25S).

There is no setting that has to be chosen to designate a control channel frequency. The scanner will check the frequencies entered, looking for the control channel data stream.

Always leave the 'primary' control channel, as well as the alternates as designated on the system's database page.

The frequencies that are colored red, and have a small letter 'c' beside them are the control channels. All of the tagged frequencies should be including when creating the system. Some systems retain the same control channel frequency, unless it is not working. Others change among the designated control channel frequencies on a regular basis.

For L3-Harris systems, any frequency might be used as a control channel, and they often rotate among the site's frequencies. In that case (a Harris system) all of the site's frequencies should be programmed.
