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。

我目前想要一个uv段模拟车载台，25w发射功率，面板、屏幕ui与八重洲ftm510dr差不多，并且带驻波功率表，价格不贵😀

楼主可以考虑下，把这个开源项目（https://github.com/nakhonthai/ESP32APRS_Audio ）的硬件复刻出来

楼主提到的这两个应用有大量高集成度的Sub-GHz芯片，集成了本振PLL和射频处理，可以调研一下，成本非常低

@"BI7ALG"#p98135 这玩意。。黄鱼一大把啊

@"BG2EFX"#p98229 黄鱼多贵啊，就没有性价比的选择

@"BI7ALG"#p98230 这玩意开源了啊。。。去jlc嫖啊

I'm a newbie getting started. Currently, my projects at the lab involve RF/FPGA development. I've been thinking about applying my existing knowledge to HAM hardware development. I was wondering if any of you seniors have any interesting project recommendations? Your guidance would be greatly appreciated.

I'm now considering building a 433 MHz band transmitter and receiver, or an FM band radio, using an FPGA development board and a mixer.

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. 😀

The original poster might consider incorporating this open-source project (https://github.com/nakhonthai/ESP32APRS_Audio ) has been replicated in hardware.

BI7ALG This... there are a lot of yellow croaker here.

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.

BG2EFX How expensive are yellow croaker fish? There don't seem to be any affordable options.

This is open-source... go to jlc and use it.
