Radioclub OK1KVK/OL7C

During my military service at the end of 80's i visited periodically one and half year radioclub OK1KVK in Karlovy Vary spa town. It was so pleasure, meet every tuesday evening local HAM's. During the years contacts disappeared, but i revive relationship with OK1KVK via Vlada OK1FIK in recent past.

Vlada OK1FIK and Pavel OK1AW are invited me to participate on CQ World Wide WPX contest, CW part, 2009. I was very proud on it. Share HF operating room with two ex-marine radio officers was great honour for me. It was new experience for me as for QRP operator too. Sitting behind a "big gun" RIG and making every minute new DX station several hours continuously, this was totally exciting for me.

Thank you, mariners.

Family radioclub OK1RKZ

During the last Field Day at OK1KVR radioclub my daughter tried to operate the youth part of the contest and made about 30 QSO's. She likes it at first attempt and after this we activated our family radioclub OK1RKZ at 144 MHz. We purchased portable mast, borrowed TRX Icom IC-706, found my old 4 element Yagi antenna and during the every third sunday of the month me and my daughter are active in OK activity contest. If its bad weather, we use our home QTH facility.

Radioclub OK1KVR

Last two Field Day contests i spend with my friends from OK1KVR radioclub, located at Vrchlabi town in Krkonose mountains. First weekend of July i usually enjoyed my holiday at Turnovska bouda cottage, which is near to Vrchlabi and then is so easy to participate at this action.

Ionosphere monitoring

In november 2006 i started 24 hours real time spectrum monitoring of special QRP beacon OK0EU. This beacon transmitting at actually (august 2007) 5 accurate and stable frequencies with 4 Hz separation, from 5 different locations.

Signal from 50 metres long wire receiving antenna (installed 15 metres above ground at Praha Ruzyne - JO70DC) leads to TRX IC-706 through high voltage protection. AF signal from TRX leads to soundblaster of conventional PC, where running Spectrum Lab software with FFT analysis.

Spectrum images, captured every hour, are uploaded via FTP to website automatically.


At spectrograms is possible to observe several infrasound phenomenas in ionosphere above the Czech Republic, displays as Doppler frequency shift on HF carrier. It can be recognized ordinary and one or more extraordinary rays, dispersion of carrier, drop out of space-wave (when the critical frequency dropped below 3.5 MHz) and others.

Project is realized with support of OK1DCP, scientist of Institute of Atmospheric Physics, Department of Upper Atmosphere, which is operator of OK0EU beacon also.

Beacon OK0EN

Beacon OK0EN i build shortly after i gets a licence. It was secondary product of my QRP activity in these years. Beacon consist from crystal Colpits oscillator, PA 300 mW INPUT, keyer (made of TTL integrated circuits - multiplexer and demultiplexer reads diode matrix, synchronized by 555 circuit timer) and power supply. It is simple, but works a years without problems.

But antenna is too bad. Dipole 2 x 20 metres, 8 metres above ground only, one of arms is under roof of family house, at lowest place in village. No space, no land. Due to vertical radiation pattern (no coverage at low elevations) i call it "european one hop iono beacon". Longest report is from Northern Ireland.


Radioclub OK1KKD

Time to time i participate on VHF and UHF contests with my local radioclub OK1KKD. Guys from club are specialized for microwave and power technology and operation. Favourite action is "Field Day", where is regularly high attendance of club members and other friends.


OK QRP Club

As a member of OK QRP club i became shortly after my several first QSO's with low power at 80 metres in 90's. OK QRP club organize meetings and contests, issued magazine, learn children build small and simple RIGs at summer camps and many others activities, all about QRP. There is no problem make a QSO to other side of Earth with PA 1 kW. It is very exciting to build small RIG himself and make QSO over ocean with 1 W with that. QRP is a HAM lifestyle.

Czech and Slovak DX Club

Radio freaks, which are listening everything is on air. Definitely, without compromise. It's a good feeling, to share this deviation.

Operation from airplane

Flying between clouds, working on the board, sometimes get a mike and make QSO. I have a good job. Really.

HAM meetings of Kladno district

Over the 12 years i organized HAM Kladno district meetings. It was fine, new friends i gets, many beers i drinked up. Thank's to continuator OK1CEP for next progress.

Big beat

Classical rock, maybe spiced little southern, that's the good food for me. I must have it several times a year, otherwise i died.

Astronomy

I like observe planets, Moon and Sun, of course. Sun is my secret love. I like everything about Sun, our star, which give us a life. I like observe also sunsets and sunrises with twilight effects and make photos sometime. Sun is life, exactly.


Czech Skeptical Club

I don't believe all. I try to get information from several sources, synthesize them, compare, think and evaluate. That's the scepticism in short.

Job

I check that radiobeacons, which are telling pilots where to fly. Responsible, but nice form of radio. Hmm, when i am not a sick on board.
