Is there a way to program an MTS2000 to listen to a type II trunked system without it logging onto the sysytem to listen only without transmit capability?

why not just get a scanner that does trunking also? It's cheaper and works well.

Yes, you can set the affiliation option to "on ptt" instead of automatic. This means the radio will not "log onto" the system as you put it until it you key up.

However, accidents happen and rather than risk keying up the system and possible ending up in a world of sh t these days you are probably better off getting a scanner. A trunktracking scanner has become comparatively cheap (to the cost of an MTS2000) even brand new.

If you use the foregoing suggestion, be sure to set the connect tone to an incorrect tone for the system to which you are listening. That way, if the radio does inadvertantly xmit a group request ISW, the channel grant will fail and voice will not pass.

This is true but you will still be affliating with the system.

Just open up the radio and remove the small metal "popple" and you won't have a PTT button to push.

Not true - you'll still get a channel grant, you just won't be able to pass any audio.



As said before:

I didn't say it was foolproof, only added protection against causing unintended interference, if you elect to go the suggested route.

Will you get a channel grant? Only part way; the radio will fail the low-speed handshake (which is done on the voice channel) and so (a) you won't get talk permit tone and (b) no audio will pass.

It depends on the type of trunked system. There is no low-speed handshake on Type II systems...it's one of the main differences between Type I & II. In Type II, my experience shows you will get a channel grant (where upon the radio gives the talk permit tones), and the repeater will key for approx .5 seconds. During this time, audio will pass. The repeater will then drop out... and the transmitting radio will continue to transmit, as it doesn't know the channel was dropped. This was tested on a 4 channel MTC3600 system I assembled & installed last year.
