Just recently bought a used RS PRO-651. Whenever I turn it on it goes through the welcome screen and then it starts searching through the air band. It goes by way too fast to read the firmware versions, etc. Once it starts scanning it does not respond to any keys being punched. I don't have a programming cable for it but I am considering getting one. I have tried pushing the 0 button and then 1 at the welcome screen and it does not respond, nor does it respond to pressing 0 and other buttons. Just goes into searching the air band. It does receive on the air band when it hits an active frequency, just cannot control it. Am I out of luck now that radio shack has puked so many times? I could not find any support or firmware on their website now.
