<DIV>Ok got it to tune. with rxboost=1. Did I forgot to reload the data when I
made my initial test? dont know.. </DIV>
<DIV> </DIV>
<DIV>the program did told me that there was not a lot of high freq and not to
use dsp.</DIV>
<DIV> </DIV>
<DIV>But I find this odd.. Did try another URI-x, same thing. so my URI are
either bad or either both good.</DIV>
<DIV> </DIV>
<DIV>Using pin 21 and ground 19 is this a bad idea? There is a voltage going out
from my msr2000 pin 5, I dont think it would be wise to plug it to the mic in dc
on the URI..</DIV>

<DIV>Now after reading the second notice I am think if I am not mixing again

<DIV>right now I stated that my audio is flat with rxdemod=flat... Am I

unless you know t is only temporary. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The RXNOISE test suggests that there isn not enough
noise getting to the URI. It had the gain as high as possible and still doesn''t
see the amount of noise it needs. Again, that does account for your symptom. My
MSR2000 manual is a UHF unit, but the control side should be looking for the
same amoiunt of noise, I'll get out the manual. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>OK, VHF and UHF are identical here. Where you
pickup noise/rx detect audio is about 250mV. I really don't know if that is
enough to drive it all. It may not be. It is amplified in the Receiver
Audio/Squelch board to 380 mvRMS. That is off the output of U1 on the receive
audio/squelch board which in two receiver kodels is a horizontal card
under teh vertically slotted cards. In a single frequency model it is in
position 7 There is no pin where the amplified detected audio comes out, so it
requires surgery. I would capacitively couple itr to pin 1 of U1This is a place
where JU101, JU102, R7 (pot) , R4 (pot),m R6 33k and U1 pin 1 connect.
</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I'd re-check your connections and DC isolation
first. I know this audio in might have voltage pn it. Or that may be the
tranamit side. Wait! Just noticed something important. Your rxboost=0 on 28739.
The amount you're off on the level should easily be made up there. It WILL make
a difference. I just tried with rxboost=0, normal for me, and noted gain at 13
for that. I changed rxboost=1, restarted asterisk and now doe the test. Level
went to 32000 gain at 0 or 1, and failed. Too high. Backed it down and it was
ok. My point is that rxboost WILL make a difference for you. Then it is a matter
of setting squelch. I look at radio tune rxsquelch several times and set the
squelch point to be about 150 to 200 over the rxnoiselevel (labeled Signal
Strength)</FONT></DIV>

<DIV>Goerge, if you take a look at the receiver part of the mrs 2000 you will
see that it connect to the back plane by a connector, those connection then
goes to various part of the repeater for filtering and tone detection on
vairous different cards.. I take the audio signal directly from pin 5 of the
receiver board. I dont see any filtering on the reciver board. In fact
from the service manual that you can find here (for the vhf receiver) <A

<DIV> </DIV>
<DIV>on page 7 there is a block diagram of the receiver and we can easily see
that there is no audio limitting and or filtering at all on the board.
Nad the leevl that I can see on my scope is pretty close to 250 mv as stated
on the service manual..</DIV>

<DIV><FONT size=2 face=Arial>Pierre, are you sure that you are getting
wideband noise to the usb device? Before de-emphasis? I am looking at a manual
for a MSR2000 and it shows a "variable gain amplifier (U1) which feeds the
squalch detector, but alsdo feeds a low pass filter on its way to the noise
gate and also feeds a de-emphasis network (U2). Any audio after that cannot
have enough hi frequency component to make the setup for tune rxnoise work
properly, which will not let the squelch work properly. The long squelch tail
you refer to is usbradio not having its squelch set properly. And that cannot
be done without wide band noise in. The result would never have enough hi freq
noise at the uri to actually squelch the radio. What is eventually kmuting it
is the end of input PL tone...</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Just my thoughts, but I have never had my hands

<DIV> </DIV>
<DIV> </DIV>
<DIV>I manage to have our msr 2000 in the shack today cause the exiter is
giving us some trouble.</DIV>
<DIV> </DIV>
<DIV>so I said, lets fix the exiter AND plug in the URI so that I wont have
to do this on site.</DIV>
<DIV> </DIV>
<DIV>exiter is ok, well for now...</DIV>
<DIV> </DIV>
<DIV>So I connect the URI pin 22 (mic AC) to pin 5 of the receiver inside
the msr2000, why 22 there is a big dc bias at this place so uning the mic dc
would nt be wise, I beleive..</DIV>
<DIV> </DIV>
<DIV>now I go to the computer set active radio usb 28739</DIV>
<DIV> </DIV>
<DIV>now I do radio tune rxnoise.. It fail.</DIV>
<DIV> </DIV>
<DIV>there is at leat 200 mv of audio there. changed rxboosst in
usbradio.conf for that node, reload, no difference.</DIV>
<DIV> </DIV>
<DIV>still did the radio tune rxvoice and rxtone.</DIV>
<DIV> </DIV>
<DIV>then tested without saving , I have a big white noise at the end of
every receiption before the coutesy tone..</DIV>
