Thanks for the reply.I felt that would be the case but I am still bushed to explain the two radios I am currently using as a repeater one on 517 and the other on 507 and their working well as far as I know .I have come across one or two of these radios that even programming them in band I carn;t get them to lock at one end of the band so they must be faulty Thank You, Ian Wells, Kerinvale Comaudio, 361 Camboon Road.Biloela.4715 Ph 0749922449 or 0409159932 or 0749922574 www.kerinvalecomaudio.com.au -------Original Message------- From: Ham-Radio Date: 3/16/2010 6:38:12 PM To: [email protected] Subject: RE: [Repeater-Builder] Maxon sm4450ne Ian, The SM-4450-NE is 488 to 512. If you program 517 you are out of band for that radio.. The ones I have are the NC 450-470 and two special order NB 420-450 radios. The NB are not available anymore. I know on the ones I have, when you get more than about 1 MHz out of band the PLL will unlock with error 3. I hope this helps. Charles Miller
