I have never seen this type of behavior - but I know what it is
(read on).

This is when I figured out what it was...

Nice of Kenwood to finally put a proper serial port on the back of the
radio instead of requiring a separate interface (like on my 850).
At any rate, please turn to Appendix A on the manual. Use the serial
interface connections as shown under SERIAL INTERFACE. Only connect
the three wires shown (serial out / serial in / ground). On the
RADIO side of the cable, make jumpers as shown in the NOTE (pin
1 to 6 and pin 4 to 7).
Your problem should now be fixed.
The reason it wasn't reading the radio until you "transmitted" is
because the PTT or CW signals were enabling the serial interface
flow control signals.
Obviously, now that you have made these changes, you will find
pins 4 and 7 are now free on the computer side and you CAN use
it for keying the radio.
