155.265 might be an ems, fire, local government, or similar use.
I manage the radios and FCC licenses for an EMS agency and our town. I have a vested interest in having every radio on our systems properly programmed and utilized. I have the final say on all gear used under our licenses.
it is inappropriate to ask on a hobby forum in place of dealing directly with your radio manger who will give you correct information so that your radio works on their system properly and does not cause Interference. Many systems have standards for personally owned radios so your radio manager may have information, advice, and possibly approval.
Talk to your radio manager for this info.
