CHIRP

No Hurry, just a wish! For Baofeng UV-5R/UV-5RA and UV-82 you can define the frequency-limits (frequency-span), so, I would like the limits given in the technical setup section being used as the actual limits when you define the given channels frequencies.
E.i. I have raised the upper UHF limit from 520Mhz to 522Mhz :-) but is not allowed to enter frequencies above 520Mhz in the channel-list (Baofeng original spec.).
For the moment I program with a random frequency and the correct name and other settings, upload it to the radio and re-program and save the correct frequency via the keyboard.
Is it something I can do by my-self? Moving some parameters? (I'm only an old-school embedded assembler programmer with start in 1974 and to >2010).
Best Regards and thanks for the (in generel) well function program
