Episode 204 - Kai Siwiak - KE4PT
One of the best kept secrets of amateur radio is the amazing QEX Magazine published by the ARRL and edited by my guest today, Kai Siwiak, KE4PT. If you are a home brewer and want a more indepth amateur radio technology understanding, then QEX should be on your desk every month. Kai provides a fascinating look at home-brewing, the digital modes, and modest antennas for the antenna challenged ham in this episode of QSO Today.
