Re: RFI from uBitx TX after AGC and other mods installed

I finally had a chance to start looking into this on my ubitx (I'm seeing the same issue). I managed to borrow a scope and putting it on the 5v supply seems to indicate that you're right. I see up to about 40 mv p-t-p on the 5v line when xmitting SSB with the AGC board not connected at all. It's pretty clean in receive. I'm tapping into the 5v line on the raduino. So that certainly looks like the smoking gun.
Now to figure out how it's getting in there...
Hope this helps...
