apocalypse 萌新入坑。现在在单位实验室里做到的项目涉及到射频/fpga的开发。最近想复用一下已有的知识入坑HAM硬件开发。不知道各位前辈有没有什么有意思的项目推荐，还请不吝赐教。 现在想的是用fpga开发板+混频器做一个433MHz 波段的发送与接收机。或者一个FM波段的收音机。
BG0EWT I'm currently looking for a UV band simulation mobile radio with a 25W transmit power, a panel, screen UI similar to the Yaesu FTM-510DR, and a VSWR meter, at an affordable price. 😀
BI7ALG The original poster might consider incorporating this open-source project (https://github.com/nakhonthai/ESP32APRS_Audio ) has been replicated in hardware.
Quarix The two applications mentioned by the original poster utilize a large number of high-integration Sub-GHz chips, which integrate a local oscillator PLL and RF processing. It would be worthwhile to investigate these, as they offer very low cost.
