Hello all, name is Sam aa8wl and I picked up a TenTec Pegasus 550 at an estate sale and I am trying to get the thing up and running. Here's the issue: It doe's not connect to the computer and computer screen says "Demo mode" as it is not connecting to the computer for some reason. My computer is a Dell Inspiron 1501 and I downloaded the Pegasus software and even downloaded Ham radio deluxe but neither works. Both programs I have tried and neither is reading the frequency. Did I mention that I did not get a manual with this radio. I am hoping that someone will be able to help me get this little box running. I hear it's a nice little box and I would like to run it for awhile and play with the controls like a kid with a new toy. TNX in advance for any help or suggestions to achieve my goal of getting the "Box" operating. 73' de aa8wl, Sam
