I have an ft857 and want to be able to move it from base station to mobile. I was trying to figure out where to mount the radio in my 2001 Grand Cherokee and couldn't really come up with a good place...then I finally realized/remembered the 857 has a detachable face so I didn't need to mount the radio, only the face. Much easier.
I already had a laptop mount installed for a previous job that I rarely use anymore so I figured why not utilize it. I made a little bracket that fits in the hole where the laptop "plate" normally goes. Works great. As an added bonus, while I was installing it, I found the face had a 3.5mm jack for headphones. I had never noticed that before. It just so happens I have an RF Modulator permanently installed that I used to connect to my laptop so the laptop sound would come over the car speakers. Well I can plug that into the headphone jack on the radio face now.
The radio itself just sits in the back seat footwell for now.
