The form factor is similar to the QYT KT8900, but with a large and easy to read color display. The design is similar, but not identical to the KT8900D, its dual band “brother”:
It is worth nothing that this radio is quad-watch also. That it, you can monitor 4 frequencies/memory channels at once, instead of the standard 2. This is a really useful feature.
