tx with hackrf one unstable

[F4IYV]

Hi André,

I have strange issue on Remote SDR in TX mode. I use hack RF one for TX and RTL SDR for RX. I run your image on PI4 4.4 (last one) When I press tx , the system pass in tx (with red key) but after 2 or 3 cycles the Hack RF crash. :( After that when I go in tool --> hack RF I can't see the hack RF (it's like unpluged) If I connect disconect the usb cable to the rf one It's work again for 2-3 TX cycle then crash.

in this test I have disconnect PA and preaplifier to avoid any problem of HF 5V of the pi seems stable

do you have an Idea? many thanks Jeremy

2 possible solutions.

• change the power supply. between 5V or 5.3v, you can have different situations.
• change the USB cable to the Hack RF. With some cable I had some issues.

Hi André,

I have verify the power supply and cable, same problem also with antoher pi. (I use lab Pwr supply) on my computer no problem with SDangel. additional information: the tx led stay off when I press tx.

I run HackRF hackrf_info version: unknown libhackrf version: unknown (0.5) Found HackRF Index: 0 Serial number: 0000000000000000f77c60dc27a76cc3 Board ID Number: 2 (HackRF One) Firmware Version: 2021.03.1 (API:1.04) Part ID Number: 0xa000cb3c 0x006f4f64

Enter the last 4 digit 6cc3 of the serial number in the configurationTX.js file at the bottom.
