Actually I think with the pre-amp I might have had a loose connection and had to adjust the gain. It seems a lot better now.? I actually got around 130mv p-p at vol high with 100uV into the antenna.? I might have been getting inconsistent readings due to the breadboard loose connections or something.
Also often I would do some initial on air tests with a ham stick before switching over to my full 40m dipole.
I need to do more testing but the on air tests sound really good with this pre-amp in place now and connections good.
I might need to actually dead bug the pre-amp onto an actual board to keep the connections from being loose.
