Member of the contest station OK1KSO, OK5W;


Club member of FOC # 1729, HSC # 753


Hello and thank you for stopping by.

I Love the hobbie and I am highly fortunate to have been introduced to amateur radio in the late 1960’s, which has been a great joy ever since. Was first licensed in 1972. My previous call sign are OL4AQA than OK1JCW. I have always had an interest in electronics and various sciences. My dad, who has always been involved in electrical troubleshooting, kept me interested in the electronics field. Always something new to learn. I hope to enjoy this hobby forever as it's educational and gratifying.

As a part time job I servicing comunication equipment, primarily ICOM, but also servicing Kenwood, YAESU, Alpha, OM/POWER Amps when workloads permit. I can provide service for most modern comunications equipment, including surface mount technology. I have a fully equipped service bench with state of the art test equipment.

I am primarily focused on 160-10 meter CW operations. I am a very active Dxer. I have 340 (all confirmed by QSL cards) DXCC(live) entities, and a few deleted ones.



CW has always been my preferred mode.(I am FOC member #1729); however I also work SSB and RTTY for ragchew QSO’s and in selected contests. (Mostly under the club CALL sign OK5W). No matter the distance or the duration, every QSO offers the chance to experience the magic of radio and worldwide friendships.

I am one of The Administrative Council of the Czech Radio Club (C.R.C.) as HF manager


I am married and have two daughters, ages 19 and 25.

I prefer QSL exchange via bureau. I strongly believe in the QSL bureau system and I do support it as much as I can. Bureau requests are answered without any delay compared to direct QSL requests. QSL cards can be requested via email.

If you decide to send a card direct, please use the address above.

I post QSO’s to the ARRL Logbook of the World (LoTW), and also am always pleased to send a QSL card direct or via the bureau. A special thanks to all of you that send LoTW and/or traditional QSL’s from so many places all over the world !
