On this page it's my intention to
inform regularly about my microwave activity.
Now QRV via QO-100 with 0,5W in 2,4 m dish
First EME QSO on 10 GHz with new 2,4 m offset dish.
Change from Flex-1500 to Hermes DDC/DUC SDR.
First EME QSO on 24 GHz with LX1DB.
Now back on 10 GHz EME with 45W at the feed. Worked F2TU and F1PYR.
New station setup
with FLEX-1500 SDR and transverter switch box.
Rebuild 10/24 GHz transverters in one box direct at the dish feed.
First EME QSO's on 10 GHz today: Sound clip OK1KIR.
Sound clip W5LUA.
Worked F6APE on 10 GHz RS via SCP in JN09
and seaduct to PA0, 1099 km: Sound
Worked PA0BAT on 24 GHz RS. Sound clip. Map.
Local oscillators for 23/3/1,2cm locked to GPS-disciplined reference oscillator.
Heard OY6BEC and worked OY9JD on 1296 MHz.
Soundfiles: OY6BEC - OY9JD
Installed 5,7 GHz transverterbox in tower.
Assembly of MKU57G2-transverter finished. Ready to be put into box with 7W
Repaired 24 GHz PA and installed tranverterbox in tower again.
Installed new preamp-box in tower. New PA on 13cm in shack with 125W output to
22m 7/8" Heliax cable.
Test on 23cm of 1,5m dish with feed for 23/13/6cm. All Yagi antennas taken
24 GHz: Installed Spinner WG-switch, MKU24GA and MKU243RX2 1,4 dB NF preamp.
10 GHz: Repaired transverter, preamp and PA.
Installed 24 GHz transverter/dish in antenna tower. Changed 432 MHz TX cable
from 1/2" to 7/8" Flexwell with 1 dB lower loss.
Rebuild of 24 GHz transverter finished. Installation of equipment in antenna
tower under preparation.
After repair of transverter now QRV on 13 cm again.
Now QRV /P on 24192 MHz with 48 cm dish and 50 mW. Equipment will soon be
rebuild for stationary installation and frequency move to 24048 MHz.
RF- power will be increased to 2 W in the feed horn.
Now QRV with 120W Power Amplifier on
3cm transverter repaired an rebuild in
13 and 3cm transverters taken down for
QRV /P from JO45SK in NAC 23 cm
2003-06-17 and in NAC 13cm+ on 2003-06-24.
DL1VDE will be QRV from JO73, JO74 and
JO64 on 10/24 GHz from 2003-06-17 to 21. Skeds on DXC/WWC or +49 1723523702.

I will be QRV on 432/1296/2320/10368
MHz in the Region 1 contest 01. - 02.03.2003 only on Saturday.
23 cm transverter repaired.
My 23cm transverter needs repair, so I
will not be QRV in the 23cm NAC on 2003-01-21. I expect to be QRV again at the
end of January 2003.
My plans for 2003:
Finish 150W 23 cm PA, improve weather protection of 10 GHz equipment, QRV on 24
GHz, more antenna gain on 70 cm (4 x 23 el. vertical stacked).
