[TrunkCom] Re: Vista Compatbile Computer Scanner Program

[ka3jjz at netscape.com]

I answered this question on RadioReference, so let me repeat it and expand on it a little...

Currently no scanners can copy LTR Multinet or Passport. That means no computer support programs such as BuTel, Scan Control and others could read the control channel and trunk it.

However there are utilities that can read the control channel and display information. Most everything that is known is kept linked here, in the wiki section of RadioReference;

Anything underlined or in blue is a link.

Many but not all of these programs will require a discriminator tap to work correctly (I understand some folks have been partially successful with UniTrunker driven off the headphones or speaker, but the accuracy of the decoding is quite low).
If I understand this correctly, MPT control channels are low-speed, so a clean connection via the speaker or headphones should work. If you have a GRE PSR-500 or 600, no tap is required if you use UniTrunker. It requires its input via a soundcard, and I'm pretty sure, isn't set up to take input via a data slicer. It requires Windows, it's OK with Vista (I think - others can jump in here...), and is freeware.

However UniTrunker doesn't cover LTR. There are 2 utilities that do - however, I understand that a data slicer needs some modifications to clean up the signal to make it work more reliably. These are also linked on that article.

The folks that maintain UniTrunker seem to watch the Trunking forum at RadioReference, and all LTR questions seem to be handled on the LTR forum.
