That is one of the best radios that Realistic ever offered.
It has a Uniden "858" main board in it. Similar to the boards that the "Old" President Washington and Madison had.
It uses the UPD858 PLL chip, so whatever channel mods for those radios are, they will carry over to the TRC-458.
Also, if you do not have a service manual for that radio, the SAMS Photofacts #CB-207 covers it.

If you need it, I do have a copy of the SAMS manual for it.
It is a 5 mb zip file, so if you want it, I would have to send it to your direct email address.
