UHF/SHF contest JO60LK

Posted on by

QRV from JO60LK on 23cm. The picture shows the setup. The HiQSDR was connected to the 23cm to 29MHz transverter. The Quisk software runs on my i7 notebook. On the same machine i ran Airscout and a client for the ON4KST chat. The notebook below runs the VUSC log under Linux in Wine. The log features a CW keyer which connects to the transceiver via the interface box in the middle. The rotator control at the left side can be controlled from VUSC as well and direct the antenna towards the locator entered.

The output power was 2x100W with 1.5m dish and Quados 8.

Only a few QSO just for fun from Hirtstein JO60OM. I just wanted to try the DK7ZB Oblong at this location in parallel to our fieldday operation. Therefore i just had my FT-817 with me and annoyed a few people with my QRP signal. Because of the stormy weather it was not possible to use the full length of the mast most of the time.

V/U/SHF Contest from JO60OM

23cm setup with HiQSDR…

HiQSDR 23cm

HiQSDR 23cm transverter setup

Contest from Hirtstein. Qrv mainly on 23cm. Setup was composed new. The old 10m-23cm TRV, 2x100W PA, 1.5m dish, backside Quados-8. Changed the Transceiver to my HiQSDR. Seeing the complete Band at once is pretty nice. CW was done completely by keyboard out of VUSC. SSB voicekeyer also worked via a small audio switchbox made for that purpose. Problems upfront were dynamic microphone headsets not working properly with the soundcard input. In addition Murphy made my linear powersupply fail during testing the equipment which lead to a damage of the transverter. Luckily it was not too terrible ;)

Marconi Memorial Contest 2014

Another contest from my home location in the Elbe valley this year. Again i used the 2m DK7ZB Quadlong antenna. Its doing surprisingly well. But this time i had 200W of output. Direction southeast was pretty good again. Now ODX was 9A4V. Thanks for the good ears down there ! Also other directions (except east) were working okay. That was mainly due to the fact that i used the reversebeacon network to gather spots generated by DJ3AK. Many thanks for that as well. Also DJ5AM (very close to my location) ran a skimmer which generated a few useful spots for me. My original plan was to run my own skimmer but that was not working due to setup issues. But the receiver of DJ3AK was really useful. Getting spot into the log-window, click to the call which tunes the TRX to the frequency and takes the call over. The macro and keyboard keyer functionality did the rest ;) East direction does not work because i am located at the east side of the Elbe valley and the hill is going up too high to get over there.

The map nicely shows the directions of the valley i can operate through with some exceptions of other stations from different directions.
A nice one was F8KID and HB9FAB, HB9TYU as well as PA4VHF and OZ6OL.

VHF contest from home

Due i was not able to join the DM7A activity from JO60LK this time i decided to try a few contacts from home in JO61VB. My location is in the Elbe valley at the eastern slope. I mounted a DK7ZB Quadlong antenna to my fibre mast installed to the balcony. Find some report on the antenna here: http://dh5ym.hopto.org/wiki/?p=1138
Only 50W were available from my FT-857D transceiver because the PA was in JO60LK serving as spare.
Surprisingly even with this tiny setup from a that bad location it was possible to make some DX contacts. I just operated about 4.5hours and got 57QSO with about 190km average.
In the map the directions of the Elbe valley are clearly visible. Especially direction of Poland i was not able to work anyone. I had the impression that relatively few stations were calling CQ. Maybe that was just related to my poor RX but possibly that trend continues to move from the microwave bands to VHF as well. Using ON4KST chat it was possible to arrange for some nice contacts in addition to a few random QSO.
ODX was PA1T with 535km. Others in top 5 are S59P, HA2U, DL0LN and OM3CPF.
Many thanks to all who had the patience to copy my qrp signal.

Sept 14 QSOs from JO61VB

Sept 2014: QSOs from JO61VB

2014 May DUR Activity

Posted on by

This time a completely different setup again.
23cm 15W with Quados, 13cm 1W with double quad element (i had nothing better, sri), 9cm 5W with Wimax-Patch antenna, 6cm with dish (the green one) borrowed from DL4DTU (TNX !), 10GHz/24GHz 5W/130mW with 6cm offset dish (transverters borrowed from DL4DTU).
This time Harald, DG3UH joined and we did a number of QSO on almost all bands. Only 24GHz did not work well with DL4DTU and there was no other station activa on that band.
If i remember correct: 23cm 9QSO, 13cm 5QSO, 9cm 1QSO, 6cm 3QSO, 3cm 1QSO, 1.2cm 0QSO.

Marconi Memorial Contest 2013

Posted on by

We did not have enough operators for a DM7A operation from uphill. I did not want to skip the contest completely and therefore i did the Marconi Memorial 2013 for 6 hours on sunday from Triebenberg JO61XA. The setup was somewhat unsual. I used a portabel setup consisting of my FT-857D and a HL-200V/50 and a 11ele Tonna. I had to power the station from my 1kW gererator.
Before i was a bit sceptical about the capabilities of the setup because the FT-857D is definitively not made for VHF contest operation. But since i have a narrow CW filter and the station densitiy was quite low i was lucky and faced absolutely no overdrive of the RX and almost no QRM by closeby stations.
In the end i had a total of 120QSO with about 36500 points.

One of the first qso was the ODX with IK5ZWU/6 who had a surprisingly strong signal for about 830km distance. MNI TNX Walter !
