LibreSDR no TX output!

[raimund56]

Hello,
I testet my LibreSDR with SDR-Console Version 3.3 build 2848 Ethernet and USB connection
with following firmware. LibreSDR is booting from the SD-card.
1 -(SD-card JT 2024 02 03) was shipped with LibreSDR
2 - Tezuka-3c31 F5OEO
3 - overclock-cpu900_ddr650
RX, works well without any problems.
TX, no output signal, if i change frequency sometimes peak on correct frequency comes up to 0dBm and goes down immediatley.
In the Spectrum i see a signal -50dBm a few 10kHz below the target frequency. ALC-Meter of course remains at "0".
All tests on TX1.
Have you any idea what the problem could be.
Thank you in advance!
Raimund

LibreSDR with tezuka and sdrconsole tx is working here. If you consider using tezuka, you can write an issue with details on https://github.com/F5OEO/tezuka_fw/issues

Hello,
I was able to solve the TX-problem with an external USB-soundcard.
It seems SDRC does't uses the internal mic input with sampling rate 48kHz.
