This is the last day of technical conference talks so its packed to the gills with content. There is also a closing talk with Ben Hilburn and Derek Kozel where they close out the conference with a bunch of information. Along with a reveal that all or almost all of the workshops have been recorded… Continue reading GRCon20 Virtual Conference Day 4
More amazing talks from day 3 for GRCon20, Im still working on the CTF but got stuck fairly quickly... I would still encourage everyone to take a look at the signals in GnuRadio, hopefully they will release solutions, not just the flag values but how they got to them! Schedule Full Conference Schedule 9/14 -… Continue reading GRCon20 Virtual Conference Day 3
The Virtual GRCon continues! The conference is in full swing, more and more people are becoming active in the conference chat and there has been a flurry of activity in the Capture The Flag Competition (CTF). The reason I went to my first GRCon was to learn from the hands-on workshops and to better understand… Continue reading GRCon20 Virtual Conference Day 2
GnuRadio Conference has gone virtual! Due to COVID-19 almost every conference is going virtual which gives many people the ability to attend that did not have the ability to before. While I miss being there in-person I believe this will have a huge benefit to the community in the long run, allowing new people to… Continue reading GRCon20 Virtual Conference Day 1
Wireless communications have always fascinated me. In school, I took digital signal processing classes, Radar signal processing classes, and even a course on wireless communication theory. But I never dived down into the electromagnetic theory. I am by no means an antenna designer, this is my first foray into antenna theory design and actual manufacturing.… Continue reading 2.4 GHz Patch Antenna Design with MATLAB
A Scalar Network Analyzer (SNA) is a type of RF network analyzer that only measures the amplitude properties of the device under test (DUT). A Vector Network Analyzer (VNA) is also capable of measuring the phase of the DUT. An SNA can be used to measure RF properties such as Voltage Standing Wave Ratio (VSWR)… Continue reading Pluto SDR Matlab SNA
A quick look at the prototype HD FPV system design provided by Fatshark after DJI announced their new HD FPV video system. Full disclosure I have not had a look at the real device and this is just info from what I can glean from the facebook post and other info on the web. Here… Continue reading Fatshark HD FPV Byte Frost

The conference program was packed full of talks, workshops, a small expo section, and lots of time to collaborate with others in the… Continue reading GRCon 2018
The invisible world of Radio Frequency (RF) drives the modern world of communications. Without it there would be no cell phones, wifi, GPS, FM radio, I could go on and on. It is often described as black magic that we are able to transmit and receive wireless data streams with amazing accuracy but it is… Continue reading Software Defined Radio
