Hi Pierre, ok looking at your output below, you did get the warning
but as mentioned earlier this happens on a lot of radios but doesn't
always mean it wont work.<br>
<br>
<blockquote type="cite">
<div>WARNING: Insufficient high frequency noise from receiver.</div>
<div>WARNING: Rx input point may be de-emphasized and not flat.</div>
<div> usbradio.conf setting of 'carrierfrom=dsp' not
recommended.</div>
<div>WARNING: RSSI=748 SQUELCH=500 and is set too loose.</div>
<div> Use 'radio tune rxsquelch' to adjust.</div>
<div>ve2mrc*CLI> radio tune rxsquelch</div>
<div>Current Signal Strength is 755</div>
<div>Current Squelch setting is 500</div>
</blockquote>
<br>
This is saying your squelch is open right now. If you take tone
decode off you will hear the squelch noise. You need to set your
squelch. <br>
<br>
When you just do a radio tune rxsquelch, it doesn't set any thing
but it reports the current measured signal and the squelch setting.
<br>
<br>
From the above info, your squelch is set to 500 and the signal is
755. To close the squelch you need to set your squelch to a value
greater then the rx signal level.<br>
To do this, type in this command:<br>
radio tune rxsquelch 800<br>
<br>
This will set the squelch to 800 which is above the RX level and the
squelch will close. Then do a radio tune save.<br>
<br>
It looks like the discriminator input is ok or it wouldn't even read
the rx level from your MSR 2000.<br>
<br>
Once you confirm the squelch is now working, you can fine tune the
squelch setting to your linking.<br>
<br>
I generally find the DSP squelch needs to be 50 to 100 points above
the idle RX level for reasonable operation. YMMV.<br>
<br>
Hope this helps.<br>
<br>

<div><font face="Arial" size="2">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> </div>
<div><font face="Arial" size="2">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> </div>
<div><font face="Arial" size="2">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>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 face="Arial" size="2">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>Got that phrase in the head, and
could not find a good title for the mail
;-)</div>
<div> </div>
<div>Ok Here I am again.</div>
<div> </div>
<div>Still with my project to have a full
App_rpt controler for my 2 repeater
system.</div>
<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>
<div> </div>
<div>what Am I doing wrong?</div>
