It was the PTT ON that was the culprit. All is working with this little beauty. Thanks!!

Subject: KX3 and digital modes
I finally upgraded my little KX1 to a new KX3. LOVE the KX3! Intent is to use it mainly when I travel, but also as a nice QRP addition to the shack. My K3/KPA500 combo is still my main shack rig. One of the things I want to try is using the KX3 with is low power digital modes, like WSPR and maybe JT65. I have been trying to hook things up to my radio laptop and so far, I have managed to get half way: JT65 decodes signals perfectly, so that side is working OK. The problem is when I plug the transmit side into the KX3 and the laptop output (speakers), the KX3 immediately flips into TX mode (little red light comes on). No RF is being sent, there are NO tones being generated from the laptop. It's like PTT is activated. Doesn't matter if JT65 is running or not, the plug goes into the laptop and the TX light goes on. I am using the supplied 'green' cable from the KX3 cable packet. It is a stereo cable. The radio is set to VOX on. If either cable end is removed, the TX light goes o
ut. What have I missed?
BTW, same results with two different laptops.
Thanks!
