RFM95 disturbes D1 Mini

[weingaunity]

Hi, a friend had a lot of issues to send LORA frames (not lorawan). The rfm-pcb and the d1 mini are stacked. When he send frames, the usb communication is e. g. corrupted.

After a lot of try&error he recognized, that a reduction of the transmission power fix this issue.
Or using 15cm jumper wire also works.

Do you also observed this issues or have any advice for us.

Thx.

Interesting, how are they stacked?
Does the RFM95 is on the top or below the D1 ?
