NAC on 3cm June 2018

June 26 we had a very nice weather here in jo44vw, 27 degrees. According to Hepburn tropo index it could look like good tropo to uk from the westcoast, so I decided to go portable with my tripod and 48cm dish and 5w .

When driving to the westcoast wearing shorts, the temperature was dropping fast, from 27 to only 18 degrees when I arrived just after 20 local time.

After the system was operational, I checked the beacons, strange DB0GHZ in JO34WE, was only 559, last time it was 599, but PI7ALK in JO22IP was 579, so conditions were good.

First I worked an OZ and a PA station, with good signals, then I tried to beam to the west and found G4ODA with 59, yes it was the right decition to go /p, later I found out that the other stations inland also did work into UK later on, so maybe I could have done that from home also… I guess so. But still I had fun out in the cold wind, and a temperature dropping to 12 degress at the end of the contest !

Next time I will try to bring some more clothes, here a map of what I did work and some pictures with a cold operator.

Station worked from JO45ID (Ballum Sluse)

10 GHz from a boot

Is it possible to work 3 cm NAC contest from a boot ?

We know that the antennas for microwave can be very small, but small enougth for a boot ?

Yes, if the boot is big enougth.

I found the big boot about 1 km from my home, it was build in 2017 in connection with the Danish Scouts Jamboree (37.000 scouts).

A cold Marts evening I went out to the boot, with my small 48 cm setup, with only 1 W.

With only 2 degrees, you wont stay for long time, so only worked 5 qso’s (not much activity).

ODX PA0T 283 km, ok with 1 W on flat conditions…

Qrv on 23cm now

I am now qrv on 23cm. Bought a complete system from oz9zz.

Here the system, a DB6NT G2 transverter and a 50 W PA from G3WDG.

Antenna is a Wimo 44 element.

Only been qrv in the NAC contest, worked 15 stations, ODX DF9IC, 671 KM.


New setup for EME on 3cm

After my first EME weekend, my good friend Palle, OZ9DT, asked me if we should make a EME system at his QTH, then both of us could use the system.
I very good idea, Palle got a 2.4m dish, but the dish was not ready for use, so we decided to borrow a 1.8m from Peter, OZ1LPR.
We spend some evenings and some concrete to make the system ready for the ARRL EME contest.

Here Palle at the system


1.8m Dish and Egis rotator


Now the system is ready for EME



At the moment we are using my tropo setup a DB6NT G3 and an Elisra 15W PA. The output at the feed about 12W and a NF about 2.3 dB. Next step is to optimize it, we need to have a waveguide preamp (already bought) direct at the feed and some more power.

System used inside : DB6NT TR144 + Hermes SDR.

Here some pictures from inside during the our Sunday





We only had time to be qrv Sunday from 6Z until our moonset at 11Z.

Here the log :

25/09/2016 07:26 HB9Q JN47CG -14 -19 JT4F EME 865
25/09/2016 07:42 UA4HTS LO43MO -12 -15 JT4F EME 2507
25/09/2016 08:42 OZ1LPR JO44UW -12 -17 JT4F EME 17

Number of QSO listed: 3

We did make 3 qso’s HB9Q, UA4HTS and OZ1LPR, we were heard by SQ7D, OZ1FF, PA3DZL & PA7JB all JT4F. Not many stations qrv Sunday on JT, our 12W was to little to work CW.


10 GHz activity 23-24 June 2016

June 23 and 24 we got some nice clouds 300-400 Km from here.

Heard PE9GHZ for the first time.

Some sound files  OZ7Z at DD7PC, OZ7Z at DL3IAE, DL3IAE at oz7z and DL3IAS at oz7z

Worked Marco DD7PC, for the first time, his first oz, here my cq recorded by Marco

OZ7Z recorde by DL3IAE

DL3IAE recorded by oz7z

DL3IAS recorded by oz7z

Marco also send me a picture of my signal, where you can see my cq + oz7z :
