a gps mouse and a Puxing 777 vhf handheld with a mic and speaker lead ,the
wire's off the mic & speaker lead are</font></div>
<div><font face="Arial" size="2">Red = Speaker</font></div>
<div><font face="Arial" size="2">White = Mic</font></div>
<div><font face="Arial" size="2">Blue + PTT</font></div>
<div><font face="Arial" size="2">Black = Ground</font></div>
<div><font face="Arial" size="2">I have wired it to a DB-9 Male plug also with a red
& Black power lead.</font></div>
<div><font face="Arial" size="2">This is how i wired it up </font></div>
<div><font face="Arial" size="2">Pin 1 = White (mic)</font></div>
<div><font face="Arial" size="2">Pin 3 = Blue (ptt)</font></div>
<div><font face="Arial" size="2">Pin 5 = Red (Speaker)</font></div>
<div><font face="Arial" size="2">Pin 6 = Black (Ground for both mic & speaker
cable and black from the red & black power cable</font></div>

<div><font face="Arial" size="2">as soon as i plug the handheld in it goes into
transmit and stays there i also have the HT jumber enabled i have tried it with
the jumper on and off and it still goes into transmit ??</font></div><br></div></blockquote><div><br>Hi David. The information looks correct. Leave the HT link OFF. That is only for handhelds that share a mic and PTT line. <br>
It might be worth metering the mic/speaker lead and confirming the wires.<br><br>Ground goes to 2.5mm sleeve<br>Speaker goes to 2.5mm tip<br>PTT goes to 3.5mm sleeve (definitely confirm this one)<br>Mic goes to 3.5mm ring<br>
Both jacks should be stereo.<br><br>I can send you a wiring diagram of the OT+ to PX777 using the free earpiece if you need it. The only difference would be the wire colours.<br></div></div>-- <br>———————<br>Rob VK6UFO<br>
