Observation 138516: NOAA 18 (28654)

Regarding Observation 138516

I did two things: QFH outside the roof. And: Pulled out the metal shield of the USB cable. I hope it helps…

When will the next NOAA come over EU? :wink:

What does pulling out the shield do?

I’m speaking about my setup only: It produces less tihs.

Compare the two waterfall pictures:




As Mythbusters says: Don’t try this at home.

Hm maybe passing the cable thru an RF choke like on the USB Printer cables might help? Could also just be something like a ground loop somewhere causing it.

This might help, too. Yes.
