Looked it up. It’s rare in my experience to see Midland radios for sale at retail. Even online they don’t register.

Of course it would help if they had an easier identifier than part of the serial number. I’ve had shorter passwords.

alot of people dont know some of the capabilities that some radios have this is my 3rd version of the 77-285 i also have a 77-285EX which looks just like the 77-285 but it has fm and factory hi/lo power i am really impressed with this 77-285 A now just to figure out some power mods for it

In EU that radio is sold as Yosan MJ-3031 - 1 final transistor or Megajet MJ-3031 - 2 final transistors.
Hygen 303 is another brand name.
