Thanks for the reply, Rusty. I got it done last night buy using the process I described in my post. It took forever. You are correct. There are no provisions for cloning or PC programming.
I had to press BAND to select the band to be programmed, then hit the SEARCH button, then the HOLD button to stop the search somewhere, then use the UP/DN buttons to fine tune the frequency that randomly appeared in the LCD screen to the exact frequency I wanted to program. At that point, I hit PROGRAM, then PRIVATE, then select the channel number I wanted to put the frequency in, then hit PROGRAM again. Multiply that times 50 channels! Whew!
The guy who invented this process must have done it as a joke.
It's a good thing that I won't need to reprogram this radio as much as I do my other scanners
