pyxmr2025 What good firmware can I use with UV-K5 (official store, original version, no expansion)? I usually listen to FM, CW, and some digital protocols.
BH5UNT pyxmr2025 The CEC firmware can transmit a clean FT8 signal, but it requires a custom-made audio cable and the use of customized WSJT-X software. See the UVK5-CEC repository for details. https://github.com/phdlee/uvk5cec/releases And the tutorial on WeChat "@XANYITOP". Although few people play FT8 on UHF/VHF = =, but Japanese people do like 144MHz DX.
