For the last week(s) I very much enjoy the colors of the autumn.
During a bike trip in my village I made a few photo's.
No sun, but I enjoyed the beautiful colors.

eQSL of Mitsuoka JO3JIS
While running through my log, to answer many eQSL's, that I had received, I noticed that I had made a QSO with JO3JIS, but not yet sent a QSL. I checked and found out that JO3JIS used eQSL, so I send him my card, with the calculated "Miles per Watt" information. I am very pleased by the quick response, because the next day I received a very nice return eQSL.
In this QSO I used 2.7 watt. With a distance of 5400 miles, the QSO is good for 2110 Miles per Watt. hi. The distance from my QTH, in the center of The Netherlands, to Japan is more than 5000 miles. So each QSO with Japan made with 5 watts or less, is good for more than 1000 Miles per Watt. My antenna is an Inverted Vee. The antenna of Mitsuoka is a Cushcraft.
Thanks for the very nice DX QSO, Mitsuoka. Hpe cuagn.

Received eQSL's with very low power
The last weeks I answered a lot of eQSL's.
In the INBOX I found many eQSL of QSO's, that were made with 5 W down to 5 milliwatt.
In many contest QSO's, I often reduce to the lowest possible power.
I start with a power that is probably to low.
When my signal is not heard, I increase my power with a small step.
I show here, a few eQSL's that were made with 36 mW and 80 mW and an Inverted V
36 milliwatt
80 milliwatt
My FT-817 makes 360 mW on the lowest setting.
I reduce 360 mW with an attenuator of 10 dB to 36 mW.
On the setting for 1 W, my FT-817 gives 800 mW.
After the 10 dB attenuator, only 80 mW goes to the inverted V.

Truckrun
Gisteren ben ik, als begeleider van een bewoner van de Cruquiushoeve, mee geweest met de Truckrun, Dit fantastische evenment wordt georganiseerd door Stichting Het Reservewiel.
Er vertrokken zo'n 80 trucks vanaf het terrein van de Cruquiushoeve in de Haarlemmermeer.
De lange stoet van vrachtwagens maakte al toeterend een rondritdoor de Haarlemmermeer.
Langs het gemaal De Cruquius |
De route ging dit jaar van de Cruquius, naar Zwanenburg en Badhoevedorp. Onderweg werd het konvooi opgewacht met een ereboog van water door de de brandweer. We kregen de volle laag van links en van rechts.
Brandweer - links en rechts |
Via Hoofddorp reden we weer terug naar de Cruquiushoeve.
Bij elke zijstraat en zijweg waar maar verkeer uit kon komen, bleef een gemotoriseerde verkeers regelaar achter, om de stoet ongehinderd door te laten gaan. Als alle trucks gepasseerd waren werd de weg weer vrij gegeven.
