For safety and convenience, you either need two radios or the ability to listen to two frequencies simultaneously. The latest Icom and XCOM for example have dual watch capability. Two radios are a little more complex and require some kind of mic switch or audio panel so a little more complex. You don't realise what you are missing on the airwaves until you have two radios.
Apologies for repeating some of previous post. I agree with it, good advice.
