I turned on my 6600 today and I notice on 15m I have birdies every 4 to 10 Khz. The same thing is showing up on 10m too but at wider Khz intervals. I haven't seen this until today. I wonder what I need to be looking for that makes this type of interference.

Yea I'm looking for these. It might not be in the house. The spikes aren't that strong and 15m is dead quiet. I did notice they disappeared for a bit and only seem to show up when the antenna is turned between NE and N.
