I have set up a Master II repeater station in full duplex mode using a URI for dsp squelch and dsp pl decode and it works just fine. The main thing is to connect it to the volume/squelch hi (raw discriminator) or you will have problems. The master II should be able to give you 1V p-p output with 1k tone @ 3k dev on the volumw/squelch hi which is not available on the back plane. You have to pull it off one of the connectors on the drawer. Have to check my notes on what pin.

Any way I have a couple of units working in this manner with no problems.

A man who has been working with app_rpt and the USB fobs for a number of years, and his sister, who has just recently gotten interested in doing the same are having a discussion: The sister asks: "Why do you have to set the squelch at least 100 points higher then the no-signal RSSI value now, but you didnt used to have to several years ago?'. He replies, "Well, thats just because of history, sis."

Well I can tell you that I have only used the URI on the Master II and other radios like the GE phoenix and Deltas. All were set to have a disc. output of 1 Volt P-P (not rms). The 1 V p-p seemed to be just right for the URI. I cant say what a modified fob would require. I did make one up and it didn't work the same as the URI. So maybe the modified fobs need more attenuation to work properly. I have standardized on the the URI, but that is my personnel preference. In the end, its what ever works. As My boss use to say "do whatever it takes to make it work".. so I did. Jon On 10/8/2010 12:34 PM, Randy Ballard wrote:

I have been having the same issue and the 470k resistor seems to make it work. Does anyone know what voltage limits are for the sound fob i see in these emails someone said 1 volt should be ok but my masterII is set at exactly 1 and rxnoise fails until i added the resistor i also tried turning it down the lowest i could get was .67 volts and it still failed. I am ok with using the resistor because it works but for future reference it would help to know if there is a magic number.

A fellow ham, KB3HJC, was having the same problem and was following the discussion last night. He ended up using a 470K.

I gave the repeater a good workout this morning and there is no question it is working right.

We are all set. I played around with some different resistor values and now all is working as it should. I used a remote base off of one of my repeaters off low power and it dug right in the noise. Thanks for all of your help! It is working great now…. I am learning as I got and I have learned a lot of ins and outs this week…

Thanks again!

Ok what level do you have with a full quieting signal 1k tone with 3 k deviation? there should be no problem if there is ~ 1 v p-p.

You can try setting thy rx boost off as Jim suggested if its too high.

The out put can be adjusted on a pot in the discriminator box on the IF board too.

try setting the rxboost=0 it looks like your signal is very loud and is overloading the A/D.

Jon,

I just got done checking things out. The same audio that is located on Volume Squelch hi is located on the backplane. I just traced the circuit back and double checked it with my VOM. Here is a link to the file I used many years ago. http://www.scomcontrollers.com/downloads/7kgem2bs.pdf

I fail every time I run the RX squelch detect from radio-tune-menu. Here are the results for that…

tune rxnoise maxtries=12, target=27000, tolerance=2750

tries=0, setting=2, meas=32767

tries=1, setting=2, meas=32767

tries=2, setting=2, meas=32767

tries=3, setting=2, meas=32767

tries=4, setting=1, meas=32767

tries=5, setting=1, meas=32767

tries=6, setting=1, meas=32767

tries=7, setting=1, meas=32767

tries=8, setting=1, meas=32767

tries=9, setting=1, meas=32767

tries=10, setting=1, meas=32767

tries=11, setting=1, meas=32767

DONE tries=12, setting=63, meas=32767, sqnoise=20936

ERROR: RX INPUT ADJUST FAILED.

If I set the squelch setting low manually I can hear the squelch tail everytime I unkey. If I have someone with a noisy but legible signal it just won’t hold. I can go to cas and it will work just fine. Could it be the PL detect that is holding it from digging?

Any other suggestions?

I think the audio out lines on the back plane are de-emphasized or flat to 3k then it rolls off. Either way In this case that is not what you want. If you were connecting to a hardware controller and using the cas/RX mute then it works just fine. In the case of using DSP squelch and DSP L decode by the fob/ URI it must be connected to the Discriminator. You could also set your node to speaker out instead of flat and use the USB for the cas connection. That should work too.

I personally like using the DSP Squelch and DSP tone as it is very quick - no squelch busts! That is... if you have the RX squelch set right. ;-)

This is making some sense now. I did pull off the back plane but I never traced it back to see where exactly it was coming from. Many moons ago I followed the Scom 7k to Master II hookup info. I have always just used that same spot on all other controllers in the past without an issue and excellent audio. I will give that a try tonight. I know what pin you are referring to. It would be the same pin that you would use in a mobile conversion and it is also available where the stock PL board would plug in.

Thanks and I will give it a try this evening!

I have set up a Master II repeater station in full duplex mode using a URI for dsp squelch and dsp pl decode and it works just fine. The main thing is to connect it to the volume/squelch hi (raw discriminator) or you will have problems. The master II should be able to give you 1V p-p output with 1k tone @ 3k dev on the volumw/squelch hi which is not available on the back plane. You have to pull it off one of the connectors on the drawer. Have to check my notes on what pin.

Any way I have a couple of units working in this manner with no problems.

As a test I hooked up a ts32 and ran the output of that in the CAS/COR on the fob and it worked great! I want to try to get the built in decoder working correctly though. Another friend of mine is also running a GE Master II and he is having the same problem. When we run the rxnoise level from either the radio-tune-menu or using the radio tune command from asterisk it always fails. Anyone have any suggestions on a way to resolve this? I have another use for my hardware pl decoder so I would like to get the USB Frob working correctly!!!!

Since Im a Motorola dude and not a GE dude, I cant say this as an absolute fact, but it would be pretty darned obvious that you should be taking audio from where the stock PL board would be taking it :-). The only GE experience I have had (since perhaps the "Progress Line" days... oops, I guess Im dating myself here!!) is a GE MVP which I understand is VERY similar in basic design to the MASTR II, and the volume-sqlelch HI signal was a MARVELOUS place to find VERY nice discriminator audio in that case.
