sounds like you need about 8 type 31 ferrite beads to clip on the coax right after the receiver. this will drop the common mode induced signals.

Hi Tudor,

When the antenna is disconnected everything disappears, including the interference. This suggests that the noise from GPD travels via the ground/shielding part of the connection into the antenna system and then back with the signals.
