Open Interface by RemoteQTH.com ready 4U

   There is our new article, it is Open Interface. Middle box between your TRX and PC. The Interface is based on the Arduino open source K3NG CW keyer (link), USB to serial converters, USB audio codec and USB hub among all.

   There is a block diagram:

   The first seven pieces ready for you. More here.

   We used two of these interfaces during IARU HF contest 2014 as OL4HQ on 15m CW. We could not find any problem, no reset needed... BORE :)

News at OL7M QTH :)

   Unfortunately we do not have enough time :( Anyway we have some news there. New 5el OWA yagi for 20m band is now at 31m. It is situated above 80m wire system.

And we are not only amateur radio QTH :)

ARRL DX CW contest 2014 OL7M M/M

   Letos jsme se poprvé zúčastnili ARRL DX contestu v kategorii Multi / Multi. Byla to zajímavá zkouška techniky a také nových operátorů. Až na drobné problémy to byl pohodový závod.

First time in the M/M. Nice contest with great fun, new boys in the gang, couple bottles of „russina wine“ before the contest, sauna and totally relaxed atmosphere during the contest. Poor CONDX on 160m and 80m, average on 40m and nice on 20m,15m and 10m, where he WAS completed after 4 hours, hi. Jan OK2ZAW again done an excellent job and ALL the equipment worked perfectly. We are satisfied with all bands except 80m, where the first night were problems with the RX and Sunday were CONDX already terrible and the loss was no longer catch up. Anyway, wonderful contest, thanks for all QSOs and new national record.

CQ WPX RTTY 2014 jako OL9A SOSB80/HP

   

   Tak opět po roce CQ WPX RTTY contest. Hodně jsem se na něj těšil a po loňském druhém místě jsem si věřil na první. Cíl byl jasný, překonat 1000 QSO. Situace byla ovšem opačná. Účast byla mizivá a podmínky podprůměrné... Oproti loňsku chybí v logu polovička NA stanic.

   Díky silnému větru před závodem jsme přišli o JA sloper, který se nepovedlo před závodem opravit. Byl to určitě handicap směrem na východ.

A little bit boring contest :(  The last contest 2013: 962 QSOs, 535 Prefixes Total Score 2,272,680  Lost more than 20 % QSOs. Worked a half of NA stations... Mr Murphy came to visit us. Pavel OK1MU - OK6W did have some problems on 20m, I missed JA sloper and can not use it whole contest. Some PA problems etc.  Anyway, I did have a time to test some new equipment from www.remoteqth.com and have a fun with Pavel. We operated from one house.  Nice to be called by Alex V31RU, Allan ZS1LS, Yana YB1AR and others!  Nice competition with Stefan YU3AAA, Przemyslaw SQ8ORQ and others.  CU in other contests.

Xmas holiday and ARRL roundup 2013

   Ke konci roku jsem trávil prodloužený týden na Políčku. Kromě práce a zábavy jsme vysílali na 80m a 12m. Podmínky nám přály, na 80m jsem ještě nezažil tak silné signály z JA. Některé dny bylo šíření slabší, ale jinak spíše nadprůměrně silné. Z těch zajímavějších QSO mimo JA se povedla 3 QSO do VK (VK2DX, VK6IR, VK6YS) a moje první LP spojení s WA5VGI. Kromě 80m jsme provětrali i setup na 12m směrem na NA. Byly to krásné pileupy a to i se 4el Yagi ve 32m s cca 100m koaxu.

   První závod v novém roce byl ARRL Roundup. Provětrali jsme tři pracoviště a většinu antén. I když jsme ještě ráno ztráceli 100 QSO oproti loňsku, nakonec se povedlo starý výsledek překonat. Více na 3830.

Smoke test: 2-antennas StackMatch, QRO.cz

   Po OK RTTY závodu jsem zkusil první test "důvěry" pro nový výrobek. Jedná se o klasický Stack Match pro dvě antény s možností protifáze. Pro otestování, co vydrží, jsem použil maximální povolený výkon. Musím přiznat, že jsem feritům dlouho nevěřil, ale po tomto testu pomalu začínám.

   Příště Stack Match pro tři zátěže - antény.
