Both of you will need to have licenses. When you get your license, you are issued a call-sign, and you need a callsign to be able to transmitt, with RARE exceptions (such as when you are transmitting under the super-vision of another ham-radio operator). So, if only you were licensed, she would need another ham-radio operator to 'supervise' her while transmitting. It's pretty easy to get a Technician class license, and it's good for 10 years, and you can renew it for free, so it's a good investment.If I get my Tech license, can my wife and I talk on two separate radios to each other (i.e. mobile to mobile or mobile to base) on one license or will she need one too?
