"Zero Beating" is the topic of the current (July 19) episode of the "ARRL The Doctor is In" podcast. Listen...and learn!
Here is a video explaining in detail the MFJ-1708SDR for protecting your SDR receiver while transmitting. There is another option detailed in the August QST magazine from the ARRL. That homebrew option looks like it might be a good group project to build. And we can bulk order parts for cheaper shipping. We can discuss more at the Wednesday Coffee QSO !!
Here is some good current info on Satellites. Which ones are up, what they look like and a great explanation of how the antennas are deployed in space! Very good info for those interested in talking to the birds!
Should be a great activity to try and some nice bonus points!!
Here is a good video on an interview with Coax expert Ray Nelson N1MPD. Ask Dave site that posted this is a good site for information and I highly recommend that you subscribe to his channel after you watch the video!.
