This past weekend I noticed some crackle/static when transmitting, also heard by the people I was flying with. Noise went away when I switched off the intercom also confirmed by the other pilots. I have the PS 3000 intercom with the SL-30. I have not noticed this before and have made no system changes, it did seem that the noise occurred when I checked the plugs were seated in the sockets like a poor connection but did not occur with the intercom off.
Any suggestions on what to check would be welcomed.
