Initially, I had to find a MX 7000 side view because I "thought" it had mounting screws on the side.
I bought this bad little boy at Andy's Radio off of Telephone Road in Houston. I believe this was in the late '80s.
In my opinion, Regency made outstanding scanners. I paid $518 for it. This was a great radio due to "no gaps."
At the time, bag cell phones were around. If you were in a small city, some folks could follow a cell phone conversation.
If my remote recall is correct, this radio went from 25 to 1300 Mhz.
I believe the MX 7000 was slow scanning.
The radio crapped out when the keyboard stopped working. In the attached pic, it looks like someone bypassed the keyboard.
Later, I bought one of the best radios I've ever owned, a Regency HX-1500. The guts of the HX-1500 were quite impressive. I believe this scanner was "shielded."
This was one of the best I've own.
There was yet another slow scanner, the AOR AR 1000 which I accidentally fried after playing radio technician.
