I almost never run two switches and packs these days but I do fail to see how it complicates things. What kind of numnum can't figure out how to install two switches and two batteries and run them into unused RX ports. 6 volt packs have been recommended by JR for all of there 2.4 systems to help with there little brown out problem for almost two years now. Yet the new radios still come with a 4.8?? With a two pack system there is no rule stating you need to turn on both switches, you can run one at a time if you desire, defeats the purpose but I have been known to forget to turn them both on a time or two.
