UV-5R Mini: correct capabilities from the actual CHIRP driver (wrong radio family)

[emuehlstein]

Summary

The baofeng_uv5r_mini capabilities were sourced from the classic UV-5R. That is the wrong radio family, and most numbers in the file were wrong as a result.

CHIRP handles this radio as class UV5RMini(UV17Pro) in chirp/drivers/baofeng_uv17Pro.py:2349 — a UV-17Pro-platform radio. It is not handled by chirp/drivers/uv5r.py at all.

Verified against kk7ds/chirp @ a229fae.

Corrections

Field	Was	Now	Source
max_channel_name_chars	7	12	LENGTH_NAME = 12, baofeng_uv17Pro.py:283; UV5RMini does not override it
max_channels	128	999	UV5RMini.CHANNELS = 999 → memory_bounds (1, 999)
max_channels_per_zone	128	999	matches above
bands	VHF 136–174, UHF 400–520	5 ranges, 3 rx_only	UV5RMini.VALID_BANDS

The old 7 is uv5r.py:859 valid_name_length = 7; the old 128 is UV-5R's memory_bounds (0, 127). Both are the other driver.

The band fix is the one that mattered

Old file declared one TX-capable block 400–520 MHz. CHIRP declares:

• 108–136 airband — RX only
• 136–174 VHF — TX
• 350–390 — RX only
• 400–480 UHF — TX
• 480–520 — RX only

So validation would previously accept a transmit assignment anywhere in 480–520 MHz, which is receive-only on this radio. rx_only already exists in capabilities-0.2.schema.json and _frequency_in_bands already honors it, so this needed no code change.

modes stays ["FM"], but the reason is now correct

CHIRP declares MODES = UV17Pro.MODES + ['AM'] — NFM, FM, and AM (RX airband). So FM-only is a codeplugger output policy, not a hardware limitation. The previous note implied the radio couldn't do anything else. Behavior is unchanged; DMR selection is still correctly rejected.

Also recorded in notes

• The platform trap, explicitly, so nobody re-sources this from uv5r.py.
• That max_zones: 1 is a profile-0.1 schema artifact, not a radio fact.

Verification

• capabilities.json schema-validates against capabilities-0.2.schema.json (0 errors)
• uv run pytest -q → 21 passed
• DMR assignment against this radio still rejected: uses mode DMR, which Baofeng UV-5R Mini does not support (FM), exit 1
• --output-format chirp-csv now succeeds on an FM fixture

Side effect: this unblocks a fixture that was never actually blocked

Chicago-Offline/chioff-codeplugger-profiles-test#2 was reported blocked because FIXTURE ADD (11 chars) exceeded the 7-char limit. That limit was fictional. The real limit is 12, so the existing fixture fits and needs no rename.
