Quansheng UV-K5/K6 on M17, DMR, NXDN,... Flat Audio Mod

In this video, we'll explore the capabilities of the Quansheng UV-K5/UV-K6 on Digital Voice modes, on M17, DMR, NXDN and others, by modding the radio for a flat audio response, and hooking it up to a Module17 modem and a Multi Mode Digital Voice Modem (MMDVM). This is still highly experimental, and it won't perform as well as a calibrated, well tuned transceiver from a reputable brand. However, I believe it would still is an interesting experiment! ===LINKS=== Original author of the mod: https://github.com/mobilinkd/uv-k6-di...
