However, the Kydera DM-880 is not a perfect radio. It has some drawbacks and limitations that may affect its performance and usability. Some of the common complaints from users are:
Programming software: The software is poorly written, buggy and in Chinglish. It requires MS Excel to work and has a chaotic user interface. It also has driver issues and may corrupt zones and channels when editing codeplugs[^2^].
Error rates: The radio has very high error rates when used on C-Bridged Motorola repeaters. This may be due to a poor chipset design or implementation[^2^].
Drop-outs: The radio has constant drop-outs on TX, making it useless for repeater QSOs. It may also lose connection with the hotspot or repeater randomly[^2^].
Technical support: The technical support is unreliable and non-responsive. The sales people are non-technical and have to translate to Mandarin for the engineering team[^2^].
Compatibility: The radio is not 100% compatible with the DMR standard. It may have issues with some features or functions that work well on other DMR radios[^2^].
Battery: The battery is not removable and has to be charged with a special charger. It may also have a shorter life span than expected[^3^].
Volume knob: The volume knob has a strange lag in the encoder, causing it to be difficult to adjust the volume accurately[^3^].
The Kydera DM-880 is a radio that offers many features and functions at a low price. However, it also has many flaws and problems that may frustrate or disappoint some users. It is not a radio for everyone, especially those who expect high quality and reliability from their DMR radios. It may be suitable for those who want to try DMR without spending too much money, or those who are willing to accept its limitations and quirks. The Kydera DM-880 software 24 is the latest version of the programming software that can be used to customize the radio settings and features, but it may not solve all the issues that plague this radio.
