Is this Grundy County site FDMA or TDMA?

All TACN sites are both FDMA and TDMA. If your friend will just program the site into his scanner and just set the site to "site search" instead of site scan, he should hear whatever FDMA talk groups are on the site. On the Hippie Town site, he should hear the Chattanooga THP Dispatch 1 talk group which is still FDMA. He should also hear the Coffee Co SO main talk group which is still FDMA at this time. He should also hear TEMA, and a few others. If there is a special event in the area he should hear the TACN Mutual Aids on the site which are still FDMA.
Remember to program the system ID which is 02A5 and the WACN (if asked) which is BEE00.

 

[wtp]

well,
ID SEARCH, means that you get to hear any talkgroup, just not the ones you might have locked out.
ID SCAN, means the radio will only let you hear the talkgroups that are saved in the radio.
i do not know where you would program in the system ID.

It should also be noted that all state of TN is PHASE 2 and all new user groups shall be PHASE 2 and all older users should upgrade to PHASE 2

The RR database shows that Coffee County Public Safety talk groups are Phase 1. (Mode column = D)

TN - Coffee County (16) - Public Safety​

​

DEC	HEX	Mode	Alpha Tag	Description	Tag
48147	bc13	D	Coffee EMS	EMS	EMS Dispatch
48146	bc12	D	Manchester FD	Manchester Fire	Fire Dispatch
48144	bc10	D	Manchester PD	Manchester Police	Law Dispatch
48138	bc0a	D	Coffee SO 1	Sheriff - Law 1	Law Talk
48139	bc0b	D	Coffee SO 2	Sheriff - Law 2	Law Talk
48148	bc14	D	Coffee FD	Volunteer Fire Department	Fire Dispatch

The only Coffee County talk group that he will be able to receive with that scanner is the 48138 Coffee SO 1 talk group which is still set to FDMA Phase 1. All of the other talk groups in that list are set to TDMA Phase II.
If he sets his scanner to the Hippie Town site, he will only hear talk groups, that have TACN radios affiliated to those talk groups, on that site. Hippie town is not a simulcast site and will not have many talk groups affiliated to it such as the Chattanooga City sites would.

How can he determine if the talk group is set to FDMA (1) or TDMA (2)?

How can he determine if the talk group is set to FDMA (1) or TDMA (2)?

As I mentioned in post #9 & RMason mentioned in post #19, look at the Mode column. Although not specified in the column header mouseover box, Mode "D" = Digital = FDMA. Mode "T" = TDMA

 

[RMason]

From: Database_Administrator_Handbook_Live_Version

Talkgroup Mode​

• A – Analog (may be voice or data)
• D – FDMA digital voice
• M – Mixed (analog voice and digital voice)
• T – TDMA digital voice capable

Encryption modes shall be used to indicate talkgroups that use encryption exclusively or when encryption is partially used.

• E – Capital "E" - encryption exclusively noted
• e – Lowercase "e" - partial encryption noted.

Example Uses:

• Te - TDMA capable talkgroup with partial encryption
• AE - Analog with exclusive encryption
• DE - FDMA digital with exclusive encryption
• De - FDMA digital with partial encryption

Of course, this depends on the information in the database being accurate and up-to-date.

Yes, it shows "D" on all the Coffee Co. talk groups, which, I understand is FDMA. Therefore, if it is FDMA. I would assume he should be able to receive all the talk groups. but, as you mentioned, and he said, he is only able to receive the CCSO talk group.

 

[buddrousa]

Reread post 27 only 1 tg is phase 1 all others are phase 2 if the database says different then the database needs updating.
This pistol contains inside information.

Thanks for the clarification. I'll share this information with him.

I'm receiving Coffee Co SO and most of the time it's from Hippie town farm but I'm not getting Manchester City but I have a SDS 200 and I have been experimenting with antennas and I think I am going to try a cellphone antenna any recommendations?
