Introduction to Signal Analysis Class in Baltimore-DC

A four week free class on signal analysis using SDR’s like the RTL-SDR will be taking place in the “Unallocated Space” technology community center in Baltimore-DC area. It starts on Tuesday September 20, 2016 at 7pm to 10pm. The class will help participants set up their systems, and cover locating, identifying, demodulating, and decoding common RF signal types. On the final week they will host a wireless capture the flag competition, where students will use their skills to solve problems and earn points.

You will need to bring your own SDR hardware such as an RTL-SDR, as well as an omnidirectional antenna and a PC/laptop capable of running your SDR.

    I want to use a Raspberry pi with SDR mounted up on a tower at antenna and remotely controlled by WIFI or Ethernet cable ? To avoid coax signal loss .

    “You will need to bring your own SDR hardware such as an RTL-SDR, as well as an omnidirectional antenna and a PC/laptop capable of running your SDR.”

    These low-cost RTL-SDR type receivers are notorious for “leaking” L.O. signals through the antenna connector (remember the near field too), and we won’t even get into ground loops and how they radiate! So what do you think will happen if you have a bunch of these receivers in a classroom? Signal degradation, that’s what. I wonder if the group touting this “Class” in Baltimore have even thought about this?

        Thanks Corey, Interesting… Perhaps there are no problems because you’re not doing weak signal work or (more likely) the device are not direct down-conversion. Wish I could attend one of these courses, but I’m currently living in S.E. Asia.
