Arun Kumar, W8ARU, builds most of the gear that he uses on the air, based on a skillset that he learned from becoming an amateur radio operator in India in the 1960s. This skill set combined with advanced degrees in engineering has put Arun on the cutting edge of solar and battery technologies used in big equipment as the World is going green. Arun was also Ashhar Farhan, VU2ESE's original mentor, one of his many major contributions to our hobby. W8ARU is my QSO Today.
