506th IRRU Enhanced radio fix

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ALL CREDITS GO TO Fedora12
Fedora12 created this mod (" 506'th IRRU Enchanced Radio") and allowed this fix, i have no contributions to this mod att all, support fedora for his great work
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

All this mod does is allows to input odd freq even if frequency resolution set to .2 for example, done so ppl who dont use mod wont scroll channels for yers while odd freq is still avaible to be manually set
