As previous year 2010 and 2008, father OK2BX and me OK4BX, participated CQ WW RTTY contest with our contest callsign OL2X. We have same configuration for past couple years – power ~200W and 40–10m multiband vertical. After last years’ 930Q, I suggested we could try break 1000Q mark.

QRP VHF Contest 2011

Tagged:

never before I participated in such type of contest with QRP power. As I am getting older, I changed my opinion and bought Yaesu FT-817, true QRP rig. So, I joined contest and I am surprised, in positive way.

Také letos, tak jako roky předtím, jsme se vydali na polní den za Vláděm OK2DGB. Pomohli jsme mu ztopořit talíř na 23cm. Celou akci jsme s tátou OK2BX pojali rekreačně a vzali jsme s sebou na výlet našeho Šneka – karavan.

Backup Dxkeeper logbook online

Tagged:

Long time I used logger32 logbook program. I was not fully satisfied and then I found Dxkeeper which is part of DXLAB suite. It is ideal for my needs. I use various programs for my ham activity and all ADIF data accumulate just to Dxkeeper. It has good interface to LoTW, Clublog or UI for filling QSL cards.

Rewrite paper log to ADIF with google spreadsheet

There are situations, when I rather use pencil and paper log, rather than computer. Computer needs energy, display can be hardly seen on direct Sun, it is heavy and you need log only few contacts. Paper is much flexible, but what then?

DX Cluster on VFD display

Tagged:

I had long time on my mind idea show DX spots from DX Cluster on separate display, rather than common VGA display. Some time ago I luckily got used 2×20 characters VF display which everyone knows, in example, from shops when we pay by cash register.

Anglická konverzace

Tagged:

Tak jak lidem v Československu před časem křížila cestu Ruština, dnes se situace úplně změnila a Angličtina je i u nás, ve světě a hlavně na internetu, jazykem číslo jedna. Mě se tento jazyk od malička líbil a tak se jej učím, víceméně sám, od dob mého působení na střední škole.

Contact with R34P in WRTC2010

Tagged:

Audio is edited from R34P recordings. Photos taken during event on my side. It was 15m and I used our small 1/4 wave trapped vertical for 20–15–10m from ECO. R34P was weak by me, same as me in Russia. I had not only such inteference from other nearby stations.. Russia direction covered by near wall of big trees, signal had bounce somewhere..
