Short answer is yes.<br>
<br>
RD line is discriminator so you would need to set the USBradio file
to Flat audio. The rolloff of this output may not be enough for the
DSP decoding for DSP Carrier squelch. It needs to see more raw audio
above 3khz. <br>
So you may need to use the hardware COR lines from the repeater.<br>
<br>
If the audio level is too low, at this input then you can set RX
boost = yes in the USBradio file and do a re-cal to see if you get
it to work properly. You should not need to use a hardware amp in
the URI.<br>
<br>
As for the Pins 10 and 11, They are not inputs but are out puts from
the Kenwwod. Pin 10 is discriminator and pin 11 is RX audio and is
de-emphasized. There may be more audio from Pin 11 and if you use
this pin then set audio to Speaker in USBRadio.<br>
<br>
Pins 8 and 9 are TX audio inputs to the kenwood.<br>
<br>
Pin 8 is the TD input. This input is a "direct mod" input and is
good from dc to 3K. it is mainly used for an External Pl tone or
1200 baud data input. NOTE: this input will only allow up to 2.5 Khz
deviation no matter how hard you drive it. Ths is fixed in the
Kenwood. <br>
<br>
Pin 9 is the TA input and can take analog audio from 300 hz to 3k
but has pre-emphasis. <br>
<br>
So if you are connecting a URI to teh Kenwood, see the pinouts
below..<br>
<br>
TKR 850 -------- URI<br>
<br>
8 (TD) --------- 23 (R_out)<br>
9 (TA) --------- 22 (L_out)<br>
10 (RD)-------- 21 (Mic in)<br>
16 (EPTT)-------1 (PTT)<br>
17 (SC) --------- 8 (Cor in)<br>
12 (RXG) ------19 (Gnd)<br>
19 (TXG) ------ 20 (Gnd)<br>
<br>
You may need to add the extra audio grounds RXG and TXG.<br>

<div dir="ltr">Anyone can confirm if a signal level
of 70~90mVrms with an Output impedance: 1k§Ù or less
Coupling: AC coupling
Frequency response: ¡¾2.5dB at
10~3000Hz is enough to drive a URI or should I use the
included pre amp in the URI-X?

<div>trying to use the RD line from a tkr-750 to do

<div>And while I am at it, </div>
<div><br>
</div>
<div>pin 10 and 11 of the tkr both are signal input, 10 is
TD (tx data) and 11 is TA (tx audio) If I feed one side
of the output to the pin 10 (TD) for tone signal and the
other side to (TA) and apply repeated audio would that
make sens?</div>
<div><br>
</div>
<div>Cause I did try that and It did not seem to work.. </div>
