For those of you interested in 50mhz and above…..
Archive of several dozen technical presentations is available on the 50 MHz and Up Group for your stay-at-home reading pleasure. It is at http://50mhzandup.org/archive.html and includes info on our 10 GHz linear translator, talks on building 10 thru 122 GHz radios, IF SDRs, EME rover stressed dishes, waveguide transitions and feeds and more.
122ghz ?? Really??
Enjoy,
