Single U.FL to SMA adapter faulty

Post by AdamMaras » Thu Sep 12, 2019 10:23 pm

My second-batch KerberosSDR arrived, and the first thing I did was give it a shakedown test. The fourth SDR wasn't showing any appreciable signal (using the same antennas as the other three) but it was showing increased signal when the noise source was enabled. So I opened up the case and tracked the problem down to the U.FL to SMA adapter going from the fourth SDR channel to the case. I removed the adapter from the board, and an ohmmeter test showed no resistance from the pin to the ground (the threaded side of the SMA connector).

What do I need to do (or who do I need to contact) to get a replacement U.FL to SMA adapter so I can get up and running?

Sorry about that. Signal levels are one thing that is QC checked so it should have been caught.
