Pulsing Inerference Question..

When I am on 40M I get a pulsing effect on the baseline noise level plus it affects the AGC.
I found this is because of a strong carrier on 6.750 MHz sending out a pulse about every 1 second.
This is in a frequency segment supposedly reserved for Aviation purposes

I do not know where this is based and I can't find it on any FAA maps.
It's too close to the start of the 40M band for a Rx filter to catch it..
Any suggestions on how to "notch" it out would be appreciated..
