Stormy week

Even the inverted L was broken from the tree and the top-load was fluttering in the wind  had to stop 630m TX-ing we where lucky last weekend in the ARRL10  it was a 2 day break in only storm and rain   Rx antenna K9AY  big shower in north approaching 28M  still wide open flux over 200 WSPR page 28MHz >18000km  Lage der Aa Groningen  het oude QTH  vanmiddag 60m SWL  WSPR   2014-12-19 18:00   ZS5KAD   5.288731   -17   0   KG50mb   5   PA0O   JO33hg   9549   346   2014-12-19 17:58   ZS6KTS   5.288652   -23   0   KG43cw   5   PA0O   JO33hg   9065   347   2014-12-19 18:00   ZS6SRL   5.288739   -14   0   KG33wv   10   PA0O...

ARRL10M contest PA6K JO33ii

operators PA2AWU Arend    PA0O me  PE1BBI Gerard   PC5T Frans rig: 2x 4ele 10m h.b. Arend K3   + K3 backup Acom1000 N1MM+      Lenovo X60 "TEXEL" island location had to be cancelled due to stormy weather. We made it ourself easy and stayed closer to home in a more sheltered place. Stormy wind calmed down Friday afternoon so we could setup the antennas easy. Propagation was still good on 28MHz worldwide except the Pacific and Alaska. This could be the last good propagation ARRL10M for a long time this solar cycle? Band closed sudden at about 1700 local Saturday. Sunday was better 1 hour more propagation until about 1800 local   better USA opening including West coast NW-USA KL7 was the difficult path. site PA0V Nanko

Marjan

Ivn roden en knnv   In memorium Aan “de kleine donder” Beste dwaze, dwarse en drieste marjan Je had veel emotie, ernst en engagement Veel vlinders en vleermuizen heb je gekend Zelfredzaam, zinvol en zorgvol was je leven Ik zal je gedenken en huilen, voor even Lieve, lastige, gave en gekke marjan Ik ben er helemaal nog niet aan gewend Dat je er zo snel tussenuit geknepen bent. Ik wil je toeroepen : “blijf nog even, als je kunt’ Maar luisteren was nooit je sterkst punt. Vaarwel………….

475kHz the "another tuning methode" ervaringen vervolg

5-December 2014 For the moment the QTX behaves nice  at 24V about 4Amps All temperatures in the save zone.  No extreme heat losses meaning the efficiency is >80%  So RF power should be around 100  The output voltage is 400V tt  is about 115V effective and sinus shape at SWR 1: 2.5.  The antenna current shows about 30%  that is about the maximum i can get here I do not know the real current it is not calibrated but it will be about 2A now. The actual dead toll of IRF540 is 6 now. The last 2 blown up at switching in the 24V  The IRF540 specifies  36A  and 100V you would think a power supply would melt down first seeing  those impressive figures.   Possible the power supply 50000uF elco is causing a too high inrush current . ASP  as simple as possible this is the simple setup  added a 6A meter with 15mV drop using a shunt of Constantaan wire In fact I am almost back to wh...
