First of all the default configs are set for full duplex. (Even if
the duplex setting is not stated in RPT.conf) Since you are
connecting to a half duplex radio, you will need to set duplex =1 or
0 in rpt.conf. And set the duplex setting in simpleUSB or USBradio
to half duplex (duplex=0).<br>
<br>
If the node is in full duplex, the moment the URI sees a signal it
will key the radio.<br>
<br>
Also, you need to know what the logic is for the Sq on the PS 2 port
on the Kenwood. <br>
<br>
Does the line go HI on RX or go low?<br>
<br>
Once you have determined the cor logic, you need to know if it pulls
to ground when it goes low. <br>
<br>
The COR and PL decode inputs on the URI need to see a signal that
transitions to ground. It doesn't matter if its active hi or low.
The URI will never see an input signal if it it simply goes hi but
doesn't go to ground.<br>
<br>
If the kenwood signal doesn't go to ground then you may need to
drive an NPN transistor and connect the collector to the URI so it
sees a transition to ground.<br>
<br>
The URI doesnt care about input voltage, it only cares if the input
was grounded or not. The COR and PL inputs are pulled up internally
and diode isolated.<br>
<br>
also check to see if the SQ line goes active during transmit on the
Kenwood. <br>
<br>
I had this problen on an Icom ic 208 when connected to the packet
port. the SQ line was active on receive and transmit. <br>
<br>
I had to use DSP and the discriminator connection on the PS 2 port
to get around that.<br>
<br>
Hope this helps<br>
