Observation 3806032: NOAA 15 (25338)

Regarding Observation 3806032


I am looking for help diagnosing the problem with my setup.
I have just finished a QFH antenna in copper tube. Used a nano VNA to optimise and managed to get SWR of 1.41 at 137.5MHz.

The best images that I can pull down are these grainy grey things with no image to speak of.

I think that the prob may be in the PI setup rather than the antenna.

Has anyone had experience with this fault?


Your gain is low 7.7, increase this.

Thanks, will give it a crack.
