CHIRP

hi guys, as soon as i try to update setup on that radio, i get "Frequency requires 6.25kHz step" message, even when i try to upload some plain and simple sequential PMR446 frequencies or just to remove DTCS from a channel, uploading radio .img for reference, bug found on both windows and linux builds, moreover this bug is related with #6745, it does the exact same error provided with other radio (i checked the chipset on both models, and it is the same. I'm providing a .img file taken by CHIRP from the radio, and i'd like to point out a little thing: i checked Radioddity R2's driver, and i got on line 324 (https://chirp.danplanet.com/projects/chirp/repository/entry/chirp/drivers/radioddity_r2.py#L324) "rf.has_tuning_step = False", which is pretty weird, since CHIRP is asking me to set frequencies accordingly to a stepping frequence (which is wrong, this radio has not stepping frequencies AFAIK)
