I have a FY6900 with firmware 1.3 and ESP-01. It works fine in bode mode with a SDS-1104X-E. Voltages and baud rate are correct? Have you choose the right board...

- if the radio is distant it is a pain to disconnect the cable - avoid connector ware out - same as others openHPSDR software

Thank you m5evt for the fix. I am trying with my Angelia (100D) with protocol2 and it doesn't work (but in Thetis it is working fine). Do you have some...

linhpsdr is also available from [macports](https://www.macports.org/). Just install the pkg from macports and then `sudo port install linhpsdr` You and up with the latest commit and the app at `/Applications/MacPorts/linhpsdr.app`

you don't have gtk3 installed/available. why won't you use linhpsdr from macports? then you can build it manually.

You need to reboot. Anyway, I suggest you to use `+quartz` variant by default setting it to `/opt/local/etc/macports/variants.conf` and rebuilding gtk and linhpsdr. Another very good software is `pihpsdr`

maybe, you can resolve the problem using [macports](https://www.macports.org) with `sudo port install linhpsdr`

Have you tried the STM32F103CBT6?

Ok. Thank you @jcyfkimi
