Karen,

I have a Vertex VXA-700 which covers the 2 meter ham band and the VHF
aircraft band, but it isn't made any longer, so you'd have to try eBay
or similar. The unit does have some poor reviews for audio quality
and, in my local ham radio emergency preparedness net, we have found
that my iCOM IC-T2H 2 meter handheld gets through significantly better
than the Vertex.

That said, whenever I ask the tower at my home base for a radio check
on the Vertex, they give me a "loud and clear" even when I ask
further. And I have used it very successfully in my glider (a 12,000
foot "tower" helps!) on the 2 meter band. So, while it is not the best
it could be, it is uniquely capable and worth considering.

Hope this helps.
