During the visit we were talk about radios, portable radio activities, our amateur roots, families and other subjects. At the same time LB4YB tried to connect ISS station by packed radio, others modified garden chairs against burglars, rest eating some snack or chatting with me.
I had very good feeling during the short time spent by this visit. All together were as a big family.
Dear girls and guys from LA1OTX, thank you again for nice and pleasent evening I spent sharing your regular meeting. It will be kept in my mind for a long time. Take care yourselves and have a much fun with radio in future!
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 were invite me to participate on CQ World Wide WPX contest, CW part, 2009. I was very proud on it. Sharing 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. (May 2009)
Thanks again, mariners! (June 2010)

OK1KVR radioclub, located at Vrchlabi town in Krkonose mountains. First weekend of July I usually enjoy my holiday at Turnovska bouda cottage, which is near to Vrchlabi and then is so easy to participate at this action.
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.
It is possible to observe several infrasound phenomenas in ionosphere above the Czech Republic at spectrograms, 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.

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.
OK1KKD (see OK1KKD by OK1XED also). 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.
