Absolute newbie here. 57HS7186 from Bangalore India. Have been listening in intently but have not made a single contact yet! Hope to do so soon. Figuring out the QSL cards and don't want to be rude and not be able to send one. Hope to figure it out. Have not been able to get the HS4 working on my Mac. Somehow not been able to find the right app to open up the extracted file. Let me know if you have figured it out.
Did clear my exams last year, but licence application procedure is really archaic in India :-( Sometimes takes more than a year and it just kills all enthusiasm to take this as a hobby.
