NOTES:
This config was read from the radio.
Memory 14 = 23 cm repeater 927.1125 MHz
Memory 100-106 = air band inc. uneditable 300 MHz channels

The fix for this is to change the lower band limit in uvk5.py for band 4 in BANDS_NOLIMITS to 300.0 as noted in the source excerpt:

bands supported by the UV-K5¶

BANDS = {
0: [50.0, 76.0],
1: [108.0, 135.9999],
2: [136.0, 199.9990],
3: [200.0, 299.9999],
4: [350.0, 399.9999],
5: [400.0, 469.9999],
6: [470.0, 600.0]
}

for radios with modified firmware:¶

BANDS_NOLIMITS = {
0: [18.0, 76.0],
1: [108.0, 135.9999],
2: [136.0, 199.9990],
3: [200.0, 299.9999],
4: [350.0, 399.9999], <-- lower limit changes to 300.0
5: [400.0, 469.9999],
6: [470.0, 1300.0]
}

I will look into this, thanks for the report. Which firmware are you using?

...and thanks, Jacek.

The issue has changed with Chirp rev 20231106. Memories can be edited with the patch above, but are now written to the radio as 50.000 MHz. So something upstream is also ignoring BANDS_NOLIMITS.

With the BANDS_NOLIMITS patch, frequencies between 300-349.999 MHz can be manually inserted from the radio keypad after Chirp corrupts them during upload.

Driver appears to be working fine. The last couple of issues were from firmware - please disregard posts 9/10.
