Batboard

I have a HT1250LS+ that is set for for 450-520 MHz .. is there anyway to expand the lower end of this radio into the HAM band like into the 430 range ?? I have been searching the boards here and not having much luck ..

Any help would be great
Thank you in advance for the help

you have an S split radio, the simplest solution is to just get an R split that will do 403-470

^ that should be 403-470

The one i took out of band was deaf at 444 Mhz
