TRX-1: Help manually programming trunked system

[RaleighGuy]

I've searched for an answer and didn't find anything, and I'm asking for help. I'm traveling and am trying to program a trunked system in my TRX-1, it is showing that it's reading it, stops on the TG (wildcard) when received, but I'm not hearing the audio. It is also not recording (like it is set to do, probably because there is no audio to activate the recording).

I'm running Unitrunker, but can't figure out how to properly figure out the Base. What I thought it was seems to work on Unitrunker (as it's showing me the freqs, but not on the TRX. I tried changing the AGC, the Audio type (digital or mixed). I have a custom band plan in the TRX using one similar to one that worked on another system in the same range. But nothing.

Any suggestions or ideas? Really hope to solve this tonight as I'm going home in the morning.

if you are trying to listen to an encrypted talk groups om a system forget it because any mo scanner will not decode them.

I'm aware of that and they are not encrypted, if they were my settings play a tone.

I don't own any Whistler scanners, but I'm sure you're aware of the manual?

What system and what site or sites are you trying to program?

 

[RaleighGuy]

Thanks doesn't address this problem.

The site trunking tables must be set to Auto Fill.

The site trunking tables must be set to Auto Fill.

The options are custom, default, or splinter I'm using custom with 380 759 380 406.8125 12.5

Is it in Wake County?

Is it in Wake County?

In South Carolina, Federal facility

Under Site Options, the programming software gives you a choice of Standard, Custom, and Auto Fill. On my 1080 scanner menu the choices are Normal, Custom, and Auto Fill.

Please tell me where, I can't find it in EZ Scan

 

[tvengr]

That is because the system type is Motorola. It must be Project25.

Mystery Solved!!!!! Thanks @tvengr for your help, but the problem was I didn't have two good frequencies to work with. When the control channel changed at midnight I was able to get another verified channel and use the formula in the wiki. The key is you need two good freqs.

The base is 406.000 The offset (Step in EZ Scan) is 12.5

What federal facility is it and what were the 2 frequencies you wound up monitoring?

It was the federal prison in Edgefield, finally got it to work about midnight.

The freqs were 406.8125 and 407.0125. The band plan was 406.0 380 759 380 12.5.

Thanks I am close to that. I will see what I can receive
