Programming differences between Uniden 780xlt & 785D??

[CZ]

I was looking at a site that had programming tips for the 780xlt and they mentioned the operating guide had a error in the Trunk programming section.
So, I was wondering if the 780xlt & 785D manual's are the same (except for name of radio's & spec's. of course) , and if there might be an error still in the Trunking programming section, & that's why I'm having so much difficulty getting my 785D to Trunk.

Provide us with a description of the error. Try the attached cheat sheet for Motorola 1, IIi and II systems, the Mot II part should also work for EDACS except in step 7, rotate the VFO to your type EDACS system (6, 7 or 8 ).

hehe, I like that version! Not much reading involved!

I've got both the 780xlt and 785d, I'm sure someone around here will be able to help you out. Describe the problem that you're having and maybe we can give a little more insight?!


When I first got my scanners, it was a major pain in the butt to program them. Then I invested in a little piece of software called "ARC." Works wonders, you'd be suprised. It is definetly worth the money! The only thing that sucks about it is that there are 2 different versions for 2 similiar scanners. Other then that, I dont have any problems.

One of the things that brings my Trunking efforts to a stop is mentioned in the Cheat Sheet were it talks about programming in the other frequencies -- not knowing what the other frequencies to be put in are, stops me pretty fast.

Have looked at that program's website -- if its one I'm thinking of -- In Europe, and $70+ (US)? Kinda pricey, but may wind up having to save my $, & get it eventually....

============
Site where I saw the remark regarding an error in the 780xlt manual is: "AWH: Uniden Bearcat 780xlt Trunktracker III; Scanning Tips and Tricks" at: http://myweb.accessus.net/~090/bc-780xlt.html


About 1/4 way down the page is a section titled: "Programming Guides" it says:

If the Uniden BC780XLT TrunkTracker III is your first Trunk Tracker or trunking receiver you might find the Uniden supplied operating guide to be a bit lacking in detail (it doesn't help matters to have an error in the trunk programming section!).

I saw that, & immediately filed the question which began this thread, but intend to go back & look the site over again.

Your "bump" must mean you do not have an answer yet.

If you do not know the freqs, the Manual, Cheat Sheet nor anything will help program you scanner.

If you do not have a source for freqs, try running the search ranges, if your hit is a trunked system (the noise is notable) Press E to enter the freq into the scanner. Now the problem will be what kind of trunking system is it, Motorola or EDACS. Most users of trunked scanners can tell which it is by the noise itself.

You can take pot luck and if guessed correctly on Motorola, you can set the freq as CC only scanning in accordance with Plan 1 through 4 in the CC only section of the users manual. BTW, the CC freq may change tomorrow, so be ready to do another range search, and again for the next two days for a total of 4 searches.

If you missed, and the system is EDACS of any kind you’re screwed (I started to use another word). EDACS requires entry of all freqs in the system and programmed in a specific order, which is referred to as LCN (logical channel number). I shall amend the above to, screwed unless you have a slicer and Etrunk. And if you have a slicer, you can find the Motorla freqs also by running Trunker.

Of course, your "bump" may be completely misread by me, if so, I helped keep your query alive with my superfluous junk.

When Only one freq. is available to you, even using "Police Call", it do slow things down rather well

I'm pretty sure I know what a trunk signal sounds like, & ONCE manged to get an ID, but was told it was NexTel, so back to the drawing board, so to speak.
I heard some place or another that Trunking systems only need one frequency programmed in, & it automatically seeks out the rest.
But on the other hand, I gather, with Trunking, is that if it uses, say, 10 frequencies, & you only have 9 then it will not Trunk on any of the systems, so I don't know which is right -- "Only One Freq is required" or "You must have ALL programmed in for Trunking to work." Argh! :?

Depends on the type of trunking system. The only "flavor" that will trunk with only the control channel plugged in is Motorola (and even then, you need to set the CC Band Plan to the correct value).

What system? Where are you? What is the frequency you can receive?

Not likely NexTel.

I heard some place or another that Trunking systems only need one frequency programmed in, & it automatically seeks out the rest.

As I mentioned previously, only with Motorola will this work, and most Motorola systems have four of these CC's used as "one frequency". The four rotate duty each day, usually from CC duty one day and 3 days as VC. While assigned as a Voice Channel they function like the rest of the non-programmed VC's which are managed by the duty CC. But all CC's must be programmed for the scanner (780 or 785 in this discussion) to function continually. If your known freq is not a control channel, then you will get only talk from it when the system CC tells it to transmit the conversion and even then, if the talker releases the mike key long enough, the freq may drop and the CC will assign another freq, which you don't have programmed.

But on the other hand, I gather, with Trunking, is that if it uses, say, 10 frequencies, & you only have 9 then it will not Trunk on any of the systems, so I don't know which is right -- "Only One Freq is required" or "You must have ALL programmed in for Trunking to work." Argh! :?

ONLY CC's are required with a Motorola system in either radio PERIOD. If as you stated above, the system is a 10 channel system and you only have 9 freqs, the only time it will not work is if the missing freq has duty as CC. That day of rotation, your radio will serve will as a paperweight.

Headaches & more Trunking headaches....

Had this thing since January & never have managed to get it to work on Trunking because of lack of a complete frequency list -- and the manual seems pretty obscure on it -- am in Central valley of California - Fresno County.
I once got an ID off a frequency, but that's been it.
