Entering all of a towers frequencies into a bank is a waste of time.
Just enter the control frequency(ies) for the tower and choose plan 2. The control channel will direct the scanner to the correct working channel by itself.
If you enter all of the channels associated with a tower into the bank, what happens if a new channel is added later? You will miss that traffic. By entering the control frequency and choosing plan 2, you will always hear everything.
I have the control frequencies for the Coloma, Sawyer, and Sumnerville entered into three different banks, all set up as plan 2.....works great! Yes, entering only one frequency in a 100-channel bank may be a waste of resources, but with 1000 capability, it's no big deal.
