How long would you last?

[Devonian]

How long? 6+ months comfortably without any issue, longer if supplemented with other sources or reduced rations.

As for the comms argument, I've gone round in circles on this for months, but ultimately I've also come to the conclusion that Ham is not for me, even the uV5R's are probably more than I would ever need. I have no real need for communicating with others outside of my immediate area and so walkie talkies such as the BF-888's and my trusty CB will suffice for my needs.
