This is a web-based SDR \, which consists of a RF.server\, which sends I/Q sampled data\, at a typ ical 2\,4 Mb rate (USB limits)\, via a TCP/IP connection to any HTML5 brow ser. The browser user-agent can be anywhere in the world that an internet connection can be had as long as you have an open port you can define on y our router to pass through to your RF server.\n\nThis project evolved into four phases - first phase installing the code on an i5 multicore Ubuntu-b ased laptop. and configuring the system for a $30 V3 SDR hardware dongle\, Second phase was to add an improved hardware SDR\, one with tracking RF b andpass filters\, larger sampling instead of an 8-bit width to a 12-bit AD C which gives improved RF dynamic range overload protection when the Airsp y HF+ Discovery hardware SDR was added. Third phase was to move the RF ser ver code to a Ras Pi 3. While this worked well for 1-2 online users\, it w as nowhere near the 15-20 simultaneous internet users I obtained with an i 5 processor. The fourth phase was the port to a tiny\, and very cute\, Ras Pi Zero 2W. To give you some idea how cute\, the optional metal housing c omes with a lanyard so you can wear it around your neck!. Architecturally\ , the Zero Pi 2W\, with its 4-cores\, is software compatible to the Pi 3. All 4 phases will be shown during the presentation and the installation\, configuration. and the detailed operational manual may be found at https:/ /fms.komkon.org/OWRX/\n\nBio:\nThe speaker\, Joe Jesson\, W2JEJ\, co-found ed & was CTO of a General Electric business\, Asset Intelligence\, a GE bu siness which designed and sold remote IoT smart sensors for the logistics and energy sectors.
