I took your advice about a resistor and instead bought and installed a 50k potentiometer. Now I can adjust the input levels with that and it seems to make some sort of difference.

That said, I am only decoding P25 but the voice on some local systems makes the radio operators sound like they in a bathroom and some systems I can only get the odd word here or there.

The town next to me uses Motorola Type 2 Smartzone which I can't decode with DSD for some reason.

I think this is the end of the road for my foray into this DSD thing. Interesting and low cost experiment but not a lot of satisfaction for me.

I should give it a shot on P25 just for a lark. Only working with ProVoice so far.

Were you having the same issues with audio? I find myself being grateful just to hear the `bathroom' audio but it seems that some people are getting audio output as good as from the scanner.

Thankfully most of the money I spent has been on hardware such as speakers, USB sound card and a `hands free helper' to help with soldering wires. Approx $50 in total but all the stuff is useful to have anyway.

The old Uniden 800xlt (from 1985) scanner still works good and I do have a modern digital scanner so this was really just an experiment.

A bit "hollow room" like yes. As good as I got with the scanner I tried today I have a feeling that if I tried the one with the better tap it would be very close to as good as P25 on my 396XT or PSR 600.

I think I will go ahead and tap the 2052 so I can use it to follow voice freqs out of Unitrunker. Will use the 2050 for signal.

Found this picture on Mods.DK

Was thinking of hooking up all three while I am in there. Which is the one that is actually needed for getting ProVoice out of DSD?

Unitrunker · #26 (**permalink**) 02-04-2013, 8:11 PM

You want FM discriminator on #3.

Should Unitrunker be able to tune the 2052?

Also, would you do the voltage divider rather than just the cap?

I don't have a lot of room between the board and the case. Will it hurt to put the cap/resistor near the output plug or should I find a way to get them right on the board?

I think so. Before adding the tap. Connect the radio to your computer and configure a voice receiver in Unitrunker. If the PRO2052 tunes to the park frequency, you should be good to go.

I use a potentiometer.

Does not matter. Make sure the ground and signal wires are twisted together for common mode rejection of hum and noise.

I decode provoice no problem at all through my line in not my mic in that's probably your problem

Line in is for sure the way to go. That's what I have been using. Never got anything more than a couple syllables with the mic, or it just stopped the one scanner from receiving at all.

I felt like Marconi or something when I fired it up in town the other day. To hear voice coming out of the computer speakers was quite shocking.

I think the fastest computer you can run it on is the only way to go. The same scanner and sound card setup I was messing with one day and getting 90-95% understandable audio done on one computer, was down to like 75% on a different computer that was showing 75-85% processor usage, instead of the faster one that only showed max 50% processor load. Need to try it again and make sure there is no bloatware running. Running msconfig and restarting without all the junk in the background may help things.

Can't seem to get anywhere with the 2052. Unitrunker crashes out.

davidmc36 · #33 (**permalink**) 02-05-2013, 9:44 AM

I have the PSR tuning to freqs using Uni, don't know if I really want to attempt a tap in that one though.

Chances are that the UT crashing has nothing to do with using a 2052. I wouldn't change what you're using for tap purposes. Sounds like you need to need to iron out why UT is crashing. You might want to post what version of UT you are using.

I'm guessing you have the 2052 set up as a Signal receiver and then the PSR as a control receiver. The version of UT you are running, the operating system you are running, and an idea of what is happening at the time UT crashes would probably be helpful to Rick.

Using a 2050 with tap for signal, trying to control the 2052 with Uni for voice channels. If I can control it then I will put in a tap to run the digital TG's through DSD.

Using WXP, UT 1.0.25.12

As soon as I get everything set right and hit start it crashes right out of the program.

I do everything the same, just substitute the PSR600 instead of the 2052, and it works fine.

I tried different baud rates, not all of them, but 2400, 9600, and 19,200 with no luck.

Tried to follow what is here, but I don't see how you would set Code ASCII or Return Code Carriage Return only.

There is one difference in the setup. I have the 2052 on a real comm port and the PSR is on the Serial-USB device that came with it.

I have no trouble using Scan Control with that Comm 1 (the real one) and no problem using Scan Control with the Serial_USB (comm 9)

I successfully sent commands to the 2052 with HyperTerminal.

Awesome! The 2052 is somewhat rare so it isn't well tested. Obviously this is a bug that must be fixed. If youre up to it, here are two things you can do to help.

First, look for a crash dump. Details here.

Crash Dumps

Second, turn on Control logging of the voice receiver and repeat the process. It will likely crash but the resulting tuner log may be useful. Details here.

Thanks for the reply. I will do some more messing around when I get back home later.
In the meantime I will read up on the links provided.

It did not have time to create a Control Log.

I have a Control Log from the PSR600, any interest in that?

I have 13 Crash Dump files. Compressed they are about 7meg, you want them all?

I am using the same setup you are 2052 and a 2050 and they work very well together, the only difference is I have the 2052 DB9 cable going into a DB9 to USB adapter.

What OS are you using?

I have been trying Serial-USB and COMM Port both and still no luck.

I got some Tuner Logs now though off the Serial-USB tests. Doesn't make one every time.
