I have an MTS2000 here that I am using programmed for conventional RX only to receive a trunked system. I finally purchased the software to program it myself and have been playing with some of the settings to try to get better performance without myself owning a trunked radio. I was using the nusiance delete when scanning the trunked system to block out the control channel and some others that were taking interference. I added a repeater from New Castle County over in Delaware and that was picking up well but had a long squelch tail to it. I decided to try to add the PL to my radio on the RX side to get some of the interference down and shorten the tail, and this worked. So I added it to my trunked system I am monitoring, and it seemed ok, at first. I have now found that I can only receive the dispatch channel and occasionally I can hear a unit out in the field. Other than maybe 1 in 5 to 1 in 10 transmissions on the trunked bank, I can't hear anything anymore. The dispatch is a conventional channel and the working channels are all trunked. Anyone have any ideas? I am still working through the manual here on the CPS and learning what some of the stuff does. I really dont want to take the PL off if I can help it, as that has been great with the RX quality on most things, unless there is a better way to get around the interference and having to lock out the control channel.

What are the chances that you didn't disable the TX
on those trunking channels? The system found a way
to kill your radio on those trunking systems.

It's not nice to go play with a radio on a trunking
ystem. In most cases the radio will try to afiliate with
the system. It does this when you first power the
radio up. Unless you went to some great pains to
ensure the TX would stay off, you have probably been
sending out signal and didn't know it.

These transmissions will be recorded by the system
and the administrator will probable catch that radio
as being unauthorized to be on the system. The
system will then be instructed to disable the radio
and render it non functional on the trunking system.

It would not surprise me that you got caught.

All personalities in this radio are set to RX only, and I just double checked that before posting. Also, this radio does not have trunking abilities, it is conventional. Lastly, the radio still receives fine on two other county's channels.

Sounds like an alignment issue to me.
I would give it a full RX alignment as detailed in the service manual. If you don't have all the high dollar gear, a reputable MSS shouldn't charge more than a 1/2 hour labor to do this.

As far as the use of PL on listening to trunking repeaters in conventional mode, how does this work? the trunking connect tones are a little off intentionally from common PL tones. Maybe this is your issue, the tone freqs are off and causing the logic to mute or ignore some transmissions? Not sure if this is going on here but a wild guess.

I can guarantee that poor scan performance in conventional on a Jedi can be directly related to a misaligned RF board. Other than that, you mentioned other channels in your scan list get "interference"...maybe it's a nearby celsite/Nextel, etc?

When I went to radioreference.com, they list a PL for this system. After setting the PL tone that they list, I still can get the conventional dispatch, just not anything else. As I said in my initial post, once in a while a transmission will still get through. I will go through the alignment when I get a chance.
