The Midland MXT500 is now available to members of E3 Association and will be available next week to the public at large.
It can be either wide band or narrow band, basically it can (generally) be programmed within all legal GMRS parameters.
The MXT 575 is expected this summer.
MXT400 (will upgrade to MXT500 when released). Mounted with a JCR Off-road overhead Molle panel in my 2021 Jeep Wrangler Unlimited Rubicon. 6db antenna mounted at the bolt forward of the radio antenna. I also have a Kenwood D710GA with the antenna mounted on the opposite side (but likely moving to rear tailgate when I upgrade the Midland).
