openRetevis RT22 - Fix POWER_LEVELS and VALID_BANDS
0%
Description
Retevis RT22, as per documentation sources, has
- Operating Frequency 400-480MHz
- Output Power <= 2W
The driver contains the following:
rf.valid_bands = [(400000000, 520000000)]
...
RT22_POWER_LEVELS = [chirp_common.PowerLevel("Low", watts=2.00),
chirp_common.PowerLevel("High", watts=5.00)]
As these devices are sold as PMR or FRS devices, I think both variables could take the following values:
rf.valid_bands = [(400000000, 480000000)]
...
RT22_POWER_LEVELS = [chirp_common.PowerLevel("Low", watts=0.50),
chirp_common.PowerLevel("High", watts=2.00)]

- Tracker changed from New Model to Bug
- Equipment Loan/Gift Offered deleted (
No) - Chirp Version set to next
- Model affected set to Retevis RT22
- Platform set to MacOS
This is clearly not a "new model" request, so I'm changing the type here.

I'll let Jim chime in about the correctness (or lack thereof) of the power and band attributes.

The original RT22 that was used to develop the is a full band radio. The driver was written to support that model and needs to continue to support that model.
The majority of radios sold by Retevis and other Chinese radio manufacturers/dealers are actually full band out-of-the-box. They masquerade as FRS or PMR models simply by providing software that only lets the user program the radio per the requirements of the service that the software pretends to support. If it is full band capable, CHIRP usually will be written (or updated) to match the radio's actual capability. Models that are truly FRS, PMR, FreeNet, etc compliant will have CHIRP support to match. The BTECH FRS-A1, FRS-B1, GMRS-V2 and MURS-V2 are examples of truly compliant models for which the CHIRP support matches.
The 'watts' values are meaningless to the radio itself. CHIRP sets the radio to the Low or High transmit power selection and the radio TX power is whatever there radio is capable of when set to each value. The power 'watts' are only when transferring memories between tabs of differing radio model.
