T4Win screen ? win xp pro

[jrny99]

can anyone tell me what i am looking at, i posted this somewhere else and shouldn't have but here it is. after fumbling around a bit i finally got something happen as you can see here. i just dont know what it is i am doing wrong. i am wondering if the data slicer i bought is defective?

Are you using a data slicer? If so ... then the oscilloscope window should be blank. The o'scope display does not work with data slicers - only with sound inputs.

Click "stop" to stop decoding. Change the sampling input to from "default input" to something else like "COM1 CTS" or whatever COM port and pin combination used by your slicer.

Click "start" to resume decoding. A lot of folks have reported problems with data slicers and T4Win. Is your slicer powered by the serial port? Is so, it may have trouble working with T4Win.

If you have a microphone or line input, you might want to try that instead of the data slicer (at least until I can fix the problem).

Good luck.

well i went direct to the sound card thru the mic and now i have this? what do i do with all this info? please dont laugh cause i am trying :?

 

[SCPD]

now i have this? what do i do with all this info?

Much better. You're getting there. Looks noisy.

A few things to check ...

1. are you using shielded audio cable from the discriminator tap to the computer sound input?

2. does this sound like a valid Motorola or EDACS control channel?

3. try checking the "invert" option. You'll have to stop decoding, make the change, and then resume decoding to see the effect (if any).

This might be it. I noticed on the bottom of both his screenshots, T4Win was trying to decode a MPT1327 signal.

T4Win was trying to decode a MPT1327 signal.

FYI: T4Win decodes all known protocols (Motorola, EDACS48, EDACS96, LTR, and MPT1327) all the time. The decoders compete - whichever has the highest successful decode rate wins. In this case, for some reason (not really sure why), the MPT1327 decoder always seems to "win" when everything else is at or near zero percent.

In this version of T4Win, the LTR and MPT1327 decoders are broken (and continue to be under development) so you won't see anything useful from them.

When using a RS/GRE scanner....

Is selecting control under the com port selction of any value?

No. T4Win assumes a Uniden family computer controlled scanner - the '895, '245, '780, and the RS 2053 (I think).

BTW, which GRE scanners support "remote tuning" where they can be instructed to tune to a particular frequency?

Sadly, the PRO96 does not offer this simple yet nifty-keen feature.

RS2052

Any RS/GRE scanner that has a PLL2002 PLL chip *should* be able to be remotely controlled for setting freq,mode,squelch,step,tune etc etc etc But you have to tap into the PLL chip itself to do so. According to this page.

ok getting somewhere, here is a shot of my screen on windows98se. now the big question is..am i on the right track and now what ? the screen is moving real fast because i'm Man. on a CNTRL channel and i can move around to slow it down. is there somewhere i need to go to be able to break this all down? the decoding rate does get up 100%

 

[SCPD]

That's it!

Click on the "database" tab in the left hand view to browse the list of channels, talkgroups, and radio ids accumulated so far. Don't forget to save before exiting the program.

T4WIN, Win XP Pro, & PRO-96

I've been messing around with T4Win for about a week now. I tapped the discriminator in my new Pro-96 (hope I never have to send it in!). I'm using the audio from the tap straight to the MIC input on my Toshiba laptop via the sound card, and a Pro-93 to monitor the system.

Here are a few screenshots.

 

[scanfan03]

I have a question for you. Why didn't you tap the 93 and use the 96 to moniter it? By the way, if you need any help with the Montgomery County Texas system (It doesn't look like you will). I live in Houston, but i am just in monitering distance, so PM me.

 

[Chris-M]

I should have tapped my Pro-2053 since it sits right next to my computer.
But I wanted to be able to utilize the APCO-25 capabilities of the 96 while I'm on the road.

There are quite a few active talkgroups showing up in the T4Win logs that aren't listed in the RR database.

65
100
516
525
542
578
757
777
806
1063
1145
1298
1511
1778
2031
2037

Plus a few that popped up today that I didn't write down.

Do you recognize any of those?

Thanks!

Most of those "new" talkgroups are invalid. There are no odd-numbered talkgroups. In fact, depending on the trunking protocol in use and whatever software and/or scanner you're using to monitor, all talkgroup numbers are divisible by some multiple of 16.

Odd-numbered talkgroups indicate either a status bit being set or incorrectly decoded control channel data. If you get that many oddball IDs, then it's most likely the second situation.

[Chris-M]

?

Are you sure Dave? The talkgroups I'm working with are on http://www.radioreference.com/modules.php?name=TRSDB&sid=58 this system. I'm using DEC format. Motorola systems are divisible by 16 but this is an EDACS system.

 

[DaveNF2G]

You threw me off talking about using APCO-25 capabilities. I didn't realize that you had changed the subject to EDACS when posting the talkgroup list. Sorry.

AFAIK, there are no APCO-25 compliant EDACS systems.

Okay, the TG problem is solved. I am more curious about the statement of using the APCO-25 capablities of the 96 while on the road. What has that got to do with tapping the 96? :?

ahhhhhhh..

I should go back to being a lurker. Every time I post on here I get gunned down! 8)
