Basically, I've been trying to research what kind of walkie talkie to buy and I'm finding it confusing. All I want is a radio that I will be able to contact my wife with in the case of an emergency if we are separated when it happens (i.e an earthquake). I'm finding that the basic ones have a disappointing range of 1 or 2 miles. I live in Los Angeles and want to make sure I have a better city range capabilities as I work a couple miles from home. I understand you can buy different antennas to help with range, but the walkie talkie I liked, a Midland, did not have the ability to swap antennas out. BaoFeng seemed to be the answer, but they all require licenses, which I would do if they had online courses, but there are no classes available. Please help, I want this for emergency use. Thank you.
