Hi Bob, I have the same problem with my BCD996P2. I can remove 1 duplicate using the "find next same" and the program will crash, you loose all your work and need to start over. I found if you get frequencies in order as to have 453.1000 x 4 lined up you can manually remove them by just using the "find next" and continue. It seems to crash more if it jumps between a few different systems.
Thanks for all your hark work!!
Similar issues - same radio. I just do not have enough "how" to correctly ID.
