For when i organize the banks on my psr 500, my question is how do most of you have the regions organized in ur banks, is it smart ot have all the regions in one bank, or is fire so busy that transmissions would be getting stepped on if done that way?.....this area/montco especially, seems to be very busy with fire radio traffic and i was just wondering the best bank set up which will allow the least amount of stepped on transmissions as well as let me hear all that i can at a given time.
