glovisol it seems to me you are using a switch supply with the noise gen. This makes a lot of bad hash. How can you do measurement?

ON5HB in the schematic you posted I see 3 mixers the circles with the cross in, look at U5.

Hi kerchunk, bear in mind the processor starts overloading at -40 dbm so at - 25 input it cannot operate. You can start with a 20 db attenuator before the input, just to see it work. Later you can use a high pas filter (look at the posts here) to cut mw out.

Something wrong here, the rsp1a has only one input, no hi z. Pse explain.

You are overloading the processor of your PC. Probably you are in the red with the overload bar.

1. What antenna you have?
2. Go to the MW broadcast band and check the levels of the AM stations you receive then you can have an idea of your problem

Hi guys, there is a very well known bug with SDRplay, when you change the antenna input connection, sometimes the software does not respond and you have to switch again among inputs until it "takes". Perhaps this is the difficulty you have, as there could be a max imbalance of less than 1 db among i...

Thanks Steve,
I have plenty Arduino Uno's and will surely report my results!

I have been reading many posts on the tracking generator, but never a post giving a list of available info to build one and where to get the Arduino software. Can someone provide COMPLETE info? This could be very useful!

Hi Robert 11 I see you now are in Windows. Listen to me use sdr uno. It is easy to learn and It is the best with the rsp you need nothing more.
