Re: [chirp_users] Special Mode?
I'm looking to use the receiver out of those ranges Jim. I can manually program those frequencies into the radio but not via Chirp.

David,
You can program any valid frequencies within the published band limits of the radio (136.000-174.000 MHz and 400.000-520.000 MHz). Any programmed memory can be easily set to RX only by setting the Duplex field to "off"

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

The frequency range on the rda1846 transceiver ic inside the uv-5r is 134-174, 200-260, 400-520. Outside those ranges the RDA1846 just won't come out to play. Internally in the radio it may be actually returning an error but the firmware doesn't handle this (fails... Very silently.)
Sorry! If you want gapless RX this isn't your radio. On Jan 8, 2015 8:49 PM, "Jim Unroe" rock.unroe@gmail.com wrote:
