i wanted to get a 800mhz portable (prob a xts5000) and i wanted to set it up to scan but not transmit.
I wanted some basic ideas on which is the best way to get it setup
ie.. do i get a scanner and get the correct freqs, then setup the radio with the freqs and set it up for non tx inhibited.
I know some of you have done it and wanted a heads up on how to do it right.
pm me with answers if you dont wanna post.
since i moved to dfw they have multiple trunked systems
how to nonaffliate a trunked system

- What radios do you own?: APX4K, XTL5K, NX5200, NX700HK
Re: how to nonaffliate a trunked system
What you want to do cannot be done with the XTS5000
Better get an XTS3000 instead.

Basically, only a:
Astro Saber
Astro Spectra
XTS3000
Without the ASTRO25 trunking will work. As long as these have smartnet or better flash in them, you can monitor without the radio affliating to the system, if programmed properly. If you select Smartzone for the trunking system, it will auto-affiate. All Astro Spectra Plus, XTL5000's, XTS anything but 3000 will auto affliate and there is no option in RSS/CPS to prevent it. The option isn't there as it is in the older radios.

Lowband radio. The original and non-complicated wide area interoperable communications system
A couple of additional thoughts; please pardon if you know this already:
To program the radios, you are going to need a "system key." The system key is a small binary file into which the SysID has been bit hashed. Without it, the RSS/CPS won't allow you to change any trunking parameters.
The only frequencies that are programmed in the radio are the control channels; the radio gets all of its voice channel information via the data stream over the control channel. In some systems, the control channel changes periodically in order to give the control channel transmitter a rest.
The other data you need is the trunking format (i.e., transmission trunking, message trunking or PTT trunking), the SysID, the talkgroup IDs, the connect tone (you want to program an INCORRECT connect tone, to prevent inadvertant affiliation), and, hopefully, the alpha designations used by the system in question (so that you'll understand channel change orders). (I'm assuming a Type II system.)
When you program the radio, program "wide area" for "none," and programming "affiliation" for "on PTT" (which defeats auto-affiliation). Most trunked radios do not have an RXO or TxInhibit function, so it is a good idea to physically disable the PTT.
