[RFI] Pulsating RFI on 75b meters

[Tim Duffy K3LR]

Hello Van,

Try turning off AND unplugging your computers and TV sets. 

Your noise might be RFI generated by the switching supplies. Do you use
switching supplies or wall transformers in your shack - house? They could be
the noise maker as well.

73!

I have an s8 pulsating noise on 75 meters exactly every 53 Khz. It is
strongest on 3754 and occurs every 53  Khz up and down the band. It is weak
by the time you get down to 3595 and by the time you get up to 3966. 

Anyone ever hear this type of RFI  that is every 53 KHZ.  any ideas. ???
thanks Van W4GIW
