Hello Om/Yl/Swl and nice to meet you on this personal Info-page.

At the moment i'am enjoying the Hamradio-activity again after several years and many moves, i simply did not take the equipment out of the moving boxes, untill somewhere begin 2010 when junior asked what was all that stuff on the attic in all those interresting looking boxes ..

Many times i am together with my now fourteen year old son Rik who seems to be infected with the Hamvirus already, and is making his first steps onto the Hamradio experience and Electronics & Computing under the watchfull eye of his father also ..

Using a small setup at the moment and in SSB i only use max. 25 watts output power. Main Hf rig is/was a Kenwood TS-690S. When i am in QRP-Mood only 5 watts, which is great fun also to make the call with less.. All digimodes & CW contacts i make with 5 watts or less, Average ERP in digi/cw modes here is usually < 2,5 watt even, I Am still amazed by the awsome possibilities with QRP transmissions.Cool

And since 08-2013 we have a really "powerfull" QRP transceiver, A Flex 1500 SDR radio has arrived in our shack !

Frontview of flex-1500 QRP transceiver

To be honest, i think boxes wit a lot of knobs dont have a long operational life left, When this tiny SDR came along the Kenwood was used less and less and even the most used (power/dial/volume) knobs are covered in a layer of dust overhere rightnow ..

Some other and also nice discussion: Is life to short for QRP ?

Why QRP makes sense, well lets see some numbers i've found (and copied) from the ve3hg weblog.

Power vs. S-Units (just a clear and mathematical example)

Theoretical S-Meter Reading vs Required Power In Watts

s-9 = 100

S-8 = 25

S-7 = 6.50

S-6 = 1.56

S-5 = .39 (Note: Thats ONLY 390 Milli Watts of power.)

Jeeh Whizz, i must be very loud with my 5 watt at the maximum capable output of my transceiver.. wink

NOTE : When i try to make CW i still appologise for my bad CW, my skills stay bad and the old juncker key stays rather dirty on the contacts. .... ..

Areals: Currently i am testing the Mk 3V1 version of a homemade HY Endfed 3 bander, which i could place in my garden, The first qso's with it seemed more then hopefull. Antenna works very well without tuning and an more than acceptable SWR on the 40, 20 and 10 meter ham bands now, it is at about 5 meters height in my garden, mounted in a south-north direction more or less. It is also nice,small and even discrete.

Schematics of it borrowed from another dutch site, there are many, Highvoltage-Capacitor CAN be used to adjust 10 meter dip a bit, many different solutions possible, lengths may vary slightley on used wire / coil material ..

Peter fixing damaged wingtipSome restauration from a wing of a Schleicher Ka7 Sailplane.


My other hobby was restoring and maintenance of (vintage) sailplanes, in which i was allowed to fly as a certified soaring pilot too.The Schleicher Ka7 sailplane on my e-QSL is from 1960, has started > 46.000 times in her life and after the last restauration i did it still flies perfectly well.

Swl since 1979, licensed since 1986.

Some of my Eqsl collection is online now, uploads once a month, you can look if you already exist there with this linkbutton now.

The always actual WX prediction overhere for the next three days in my backyard : Source = www.yr.no

Meteogram of Wx the next three days

No More WX of this location on the CWOP pages, where the same data was sent constantly. (did some maintenance at the WX station, blew up my Windmeter , too close to the dipoles even with QRP repositioned it and used some nice amidon stuff now, it did suffer quite a bit and is beyond repair, if anynone has an old oregon ws2300 or pieces laying around i would be happy wx ham again.. )

My recent radioactvity

QSL Preferred Electronic, Save tree's use Eqsl, Hrdlog, and i use LOTW upload on a weekly base, Or in paper via my manager Pa2mb.
