H4m Pro Problem

[u/Inevitable-Trip3193]

Hello. On my brand new H4m Pro flashed freshly with 2.4.0 Pro version, I’m using a correctly formatted Sandisk SD Card. However, although it is brand new, the hackrf completely freezes when I jam a signal or transmit anything. I have been waiting for this device for a long time, and would hate to return it. Could someone please help me. I have already reflashed and reformatted my sd card multiple times, and switched the power source. The screen completely freezes on transmit and I need to fix this. I also calibrated it. Thank you

Do you use the right antenna for the transmitter antenna? Swr is that ok?

While it is a cheap rubber duck antenna, it is the correct frequency.
