What is your operating system and cable driver version? Stephen was able to roll back his Prolific driver to 3.2.0.0 for Windows 7 and now the PTT does not activate when using the software.

Incidentally, is it normal for the UV-5R to key up when the serial cable is present? I'm going to make a practice of always having a dummy load connected when programming this radio.
It is the case here, with two (non-counterfeit) cables. The rig keys up as soon as the software (any software) activates the serial port.
I have identified two solutions:
1. Connect the unit to the cable (power off!), prepare Chirp so that you only need to click the OK button in order to start the transfer, power the unit on, and click the OK button as soon as the rig's display lights up. The transfer begins and the transmitter doesn't turn on.
2. Put in a receive-only channel (I have local NWS in channel 1, with transmit disabled), set the rig to that channel, plug stuff in, run Chirp, everybody happy.
