Thanks. I'm aware of the limitations. I can program the frequency into memory directly into the radio but I'm looking to do that within Chirp. The program attempts to "protect" me.
There used to be a method to change the limits by swapping out the control database for the radio but the architecture has changed and that doesn't work any more.
I'd really like to be able to disable those checks.

Yes. Sort of. CHIRP will let you alter the band limits of a UV-5R and variant to a low of 1 MHz and an high of 1000 MHz. The you are able to key in any STEP compatible frequency within those limits (except you will have to arrow to frequencies below 100 MHz because you can key in a leading "zero"). Once you have the frequency in the VFO you can program it to a memory channel as you would a normal in-band frequency.
That being said, even though the UV-5R and variants will display any STEP compatible frequency between 1-1000 MHz, it won't RX/TX very far out of the factory specified band limits. My crude tests came up with these as practical limits.
VHF range 136-174 MHz expands to 127.8-176.0 MHz UHF range 400-520 MHz expands to 383.5-524.3 MHz
YMMV
