 This project evolved into four phases - first phase installing the code on an i5 multicore Ubuntu-based 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 bandpass filters, larger sampling instead of an 8-bit width to a 12-bit ADC which gives improved RF dynamic range overload protection when the Airspy HF+ Discovery hardware SDR was added. Third phase was to move the RF server code to a Ras Pi 3.  While this worked well for 1-2 online users, it was nowhere near the 15-20 simultaneous internet users I obtained with an i5 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 comes 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/
