  Yesterday in the afternoon I met Max, VK2ARZ, in the city of Praha. It was our meeting nr.3. It was my pleasure to talk with Max face to face again.  We talked about bad propagation conditions over last months and the situation of HAM communities in Australia and the Czech Republic. We...

  Yesterday morning I visited the HAM fest of Holice 2017 (August 25th and 26th) as ordinarily every year. I met old and new HAM friends from OK, OM, DL, SP and LY there. I also bought same parts on the HAM flea market and some CDs at Slovak Radio Club stand (Slovak HAM Meeting TATRY 2015 and...

SFI=68 .....

28/07/2017 09:44
This morning (July 28, 2017) the SFI was only 68 (it was almost absolute minimum).  MUF (3000 km) was about 11 MHz at 0639 UTC - according to the Ionospheric Observatory in Pruhonice u Prahy (near Prague). The 20 meter CW band was almost empty in the morning (only a few European stations and...

My QRP operation

  Propagation Conditions (especially for DX) are very poor nowadays (SFI has been under 79, there are almost no spots on the Sun, MUF about 16,5 MHz etc.). I am afraid that it will last over life of my generation.  But fortunately - I have worked with about 325 DXCC countries from this...

RETRO TX QRP - new version

05/05/2017 16:08
Because of the fact that the new (WARC) band of 60 meters has not been allowed by the Czech Authorities for OK HAMs I decided to retune the TX from 5,5 to 7 MHz. Now I operate (from time to time) also on 7 MHz band with the RETRO TX QRP (power 5 Watts). You can see the Block Diagram on Picture...

The new WARC band 5 MHz (5351,5 to 5366,5 kHz) will not be open for OK HAMs in 2017.  According to “Radioamater 1/2017” (magazine of the Czech Radio Club): The Czech Telecommutions Office says that OK HAMs can still use a few channels (from 5272.5 to 5405.0 kHz)  when they have obtained...

Member of OK QRP Club

15/10/2016 15:39
I became a member of OK QRP Club (No.: 712). The main reason: Nowadays I frequently operate my RETRO TX QRP on 80 meters CW. Its output power is only 5 Watts. I must say that it is very funny for me. I can add that on October 13, 2016 at about 2000 UTC I worked even with VK3CWB. His RST was 559 and...

Today in the afternoon (September 28th, 2016) I met Max, VK2ARZ, in the city of Prague. Max has visited the Czech Republic before his journey to Germany. It was very nice to talk with him face to face again. We have made lots of QSOs on 14 MHz CW (mainly via long path) since his last visit the...

RETRO TX QRP

19/08/2016 18:37
I am unfortunately a little old and remember old radio amateur times. A few months ago I desired to see lighting vacuum tubes again. Because of that fact I designed and constructed RETRO TX QRP which made use of the mix of modern and “classical” parts. Its construction was mostly corresponding with...
