Describe the bug Transmitting not working properly, it emits only carrier no modulation. Tested on all transmit modes, no effect. Replay mode same not working. Signal gen not working too.

On HackRF mode working with sdrangel work normally.

To Reproduce Steps to reproduce the behavior:

  1. Try transmit something, microphone, SSTV, etc...
  2. See in another SDR receiver on transmitted carrier

Expected behavior Working modulation and hear transmitted signal

Affected versions

Additional I'm tried all solutions found here, but transmit not working as well. Reference source changing not affect on transmit. I'm using Portapack TCXO. SCR_0008 Gain and AMP work properly, no burned parts ;) Also tested with full output power, still no effect.

Peripherals on screenshot: SCR_0009

SD card test looks well(experimental 16gb) SCR_0010

any ideas to get working transmit mode on portapack? Also found bug: receive not working after transmitting something, it's start working after reboot. if needed i will open a new issue.

Hello,

I can confirm replay with Portapack not working. Whenever I record something from my walkie talkie and send the signal back only noise is heard. Strangely enough, I can capture chat messages from and replay them to a flipper zero consistently. @Brumi-2021 Thank you , I will look into updating the SPI firmware.

@Tanamichi how one know if rf component/blown? try set different Gain or AMP values, and check these values affects on signal reception or transmitting most blown IC in hackRF is amplifiler in RF part.

Thanks @Brumi-2021 i will check now.
