All,

I'm relatively new to radios, and definitely new to the list - I throw myself at your mercy.

I'm trying to program a set of Baofeng UV-5Rs to use the Motorola frequencies used by a few other race teams we run with. I'm using a Mac, OSX 10.8.5, and have already installed the PL2023 USB-Serial driver successfully (I believe). I obtained the driver from: http://www.prolific.com.tw/US/ShowProduct.aspx?p_id=229&pcid=41 I've also confirmed that the USB-serial driver appears to be installed correctly, as described here: http://plugable.com/2011/07/12/installing-a-usb-serial-adapter-on-mac-os-x

I now see '/dev/cu.usbserial' in the Port field when attempting to download from the radio (which I didn't see before installing the driver). However, when I actually attempt to download, the 'Cloning' modal shows for a few seconds w/o progress, then I see the "Radio did not respond" error. The USB cable is an "official" Baofeng cable that I received with the radios from a trusted reseller, and is definitely seated correctly. I've tried using different USB ports, turning the radio on/off, restarting several times, etc. but just cannot get the radio to talk to my Mac.

I'm really hoping you guys can help; we have a race this weekend and if I can't get the comms working, I'm in a world of crap.

Thanks,

Colby
