Re: Antuino 2.0

HI all,
I had the experience that the AD8307 is verry sensitive to HF signals. For my sweeperino I had to protect it by puting it in a shielded box. Even my WSPR transmitters 0.2W were disturbing the messurements in my shack with mij Sweeperino build with RAZZIES solution of dragons . Here I see no protection at all and many HF signals coming from SI5351.
I propose puting it in a seperate shielded compartment even so the 25Mhz filters to avoid problems.
