Your options are quite limited for true dual receive. Kenwood, Icom and Yaesu all have dual, simultaneous receive. Some of them are listed above. For Dual Watch(one frequency at a time Receive, but priority on a second frequency it checks at regular intervals), they only actively receive one signal at a time.
There are a bunch of radios that fall into that Dual-Watch category.
The IC-V86 is a reasonably decent radio, by ham standards, and because you already have an Icom radio, it may be the brand you want to stick with.
An important question for you OP, what kind of a budget do you have for a new radio?
