The receiver is now complete and only the band pass filters are missing. The local oscillator is working well as does the computer interface. I could measure the noise floor on all bands and check how much USB noise there is on the different bands of interest, see the screenshots below.
I did have signal from a signal generator through the receiver, but I did not have time to do some proper MDS measurements.
I connected an antenna to C27 but did not see many signals in HDSDR. I’m thinking I may have mounted T2 incorrectly and I will probably redo it tomorrow paying more attention to the pin numbers.
