KX3 and PTT

[jsrobbins]

Wayne,

 

I saw your below note on setting up a foot switch PTT via the ACC2 jack.  

 

As an alternative, and if I am not using the MH3, is there any problem to
accomplish the same PTT function by building a jumper from a TRRS 3.5mm plug
(into the MIC jack) to two mono in-line jacks where the pins of the plug are
split into the two which support the mic (tip and sleeve) and those which
support the PTT (ring 1 and ring 2)?  I'm planning to use a Heil
headphone/mic with a foot switch for home use.  

 

I, for one, am enjoying the exciting process of "birthing" the new KX3.

"Robert,

 

You can set up the ACC2 jack for use with a foot switch. Set MENU:ACC2 IO to
LO=PTT, and connect your footswitch between ACC2 tip contact and ground.

Jim,

That is what I plan when I get a "round tuit"

Hi Jim,

Yes, you can use pull the mic's PTT/UP/DN line to ground to activate  
PTT if you split it out from the mic audio line. You could even roll  
your own up and down switches.

Hi Jim,

This is also how I hope to do the PTT control on the KX3, since I will have the tip
of the ACC2 jack set up for triggering the PTT from the RTS line of the computer.  I
bought some plugs from DigiKey but am waiting to receive the KX3 first before
building any cables.  Looking forward to receiving it soon so I can get started
making it compatible with my 6m EME DXpedition station setup!   VY 73, Lance
