Download from the Radio to CHIRP
Open CHIRP and select Radio->Download From Radio.
Select the appropriate serial port, Vendor and Model. Do not select OK at this time.
This next step is timing critical as both the radio and CHIRP will timeout if made to wait too long for the peer systems.
1) Select OK in the Download from Radio Dialog box.
2) Press the LEFT V/M key to start the radio sending.
If you have the correct serial port and were quick enough pressing buttons you will be rewarded with a progress bar and in time a populated table in CHIRP.
If on the other hand you get an error you either have a cabling problem, wrong port or are not plugged into the radio. Or you just took to long putting CHIRP in receive mode and getting the radio in transmit mode.
Pressing the V/M button will put the radio in TX mode.
