SP5KAB is the oldest amateur radio club in Warsaw. We have been active continuously since the fifties and can boast of many achievements, evidenced by our extensive collection of cups and diplomas. For several years now, we have been observing a significant increase in interest in amateur band communications. The best evidence of the huge interest in ham radio is the rapidly growing number of SP5KAB club members. Its ranks are joined by people interested in various fields of ham radio - as you know, our hobby has many faces and does not end with making radio calls. Among us you can meet advanced radio equipment constructors as well as radio history enthusiasts. In addition to meetings at the club headquarters, we organize field activities - radio activations of interesting places that deserve promotion due to their historical value. We also engage in activities related to national defence.
