Back in the day, (early 80's) I had several Radio Shack Pro-2006 scanners. There were/are several great modification books published by Bill Cheek aimed at the Pro-2006. I installed many of these useful mods including one that added a custom RS232 interface that allowed you to load memories from a simple ASCII text file. This was the "HB-232" sold by Comtronics. Of course, no longer available, unobtainium.
The software was run on a PC running MS-DOS. The installation involved making connections between the HB-232 PCB and the front panel row and column button connection points on the Pro-2006. The programmed micro controller translated the RS232 commands to basically button pushes to program the scanners memories. It worked great!
Fast forward to today. I wanted to try and implement that same concept today for my current PRO-2006. (programming the scanner memories from a PC). The closest thing I could find is a program called "Programit" which is still downloadable but the components for the interface are no longer available. The interface uses a CMOS switch IC and a custom programmed serial to parallel IC. After doing some research (lots) I came to the conclusion that it might me possible but would most likely require coding some sort of micro controller, perhaps a Pic processor?. It's been many years since I've done any programming (quick basic, some C) so I might just have to throw in the towel on this one. It's a shame because the PRO-2006 is such a great scanner but I just can't see myself programing 400 memories with manual button pushes today.
Yes, I know about the Opto interface (won't program scanner memories) and I am fully aware of the SDR world, but I like running receivers without depending on PC's for control.
An suggestions? comments?... all appreciated.
Thanks
