Our local club DARC chapter S07 participates in the DARC Club competition. See our results page here (external)<\/a>.
\nBecause of the UHF\/SHF contest and the CW Fieldday both contributing to the Club competition we went to our portable QTH in JO60OM. There is a great mix of high altitude and very nice accomodation. Find some report of DL6JZ here<\/a>.
\nBecause of some family struggle i went to my parents home already friday evening. From there its only a half hour trip to Hirtstein. We met in JO60OM around noon and started to put the equipment. This time i took my 1.5m dish for 23cm and the 1m dish was planned for 13cm. Fred also brought his 6cm and 3cm systems.
\nThe 23cm was my favourite configuration with 2x 100W (one for front system and one for the backside), the 23cm transverter with 10m IF and my HiQSDR. The Quisk SDR waterfall gives a good overview about the band and aircraft scatter can easily be identified.
\nFor 13cm my transverter masthead box with the 75W amplifier was used. Its the same that was already used first last year. Together with a PTT splitter it was possible to connect my old 5W 9cm system to the same 1m dish as well. This was working better as expected.
\nOn 6cm we had a very well working system with a old IC202 as IF transceiver. Despite not beeing used for quite some time it was still doing great.
\nFor 3cm the feed was missing unfortunately and so we skipped the band entirely.
\nSurprisingly all systems where up and running at the beginning of the contest.
\nThe focus was planned to be on 23cm because this band counts for the DARC CM. All other bads where add-on for the DARC UKW Contest Pokal OV competition.

\nThe activity saturday afternoon and sunday morning was quite good. But i had some impression that the activity from OK which was always great is somewhat declining in the recent times. Its a bit compensated by the IC9700 effect.
\nIn addition to the microwave activity i was planned in for some lightwave tests saturday evening. Jo DL3ARM does a great job motivating an increasing group of enthusiasts to try communication with visible light. So i took my old laser station to the hill. The decision was absolutely good since the weather turned out to be almost perfect.
\nJo was on the Fichtelberg JO60LK which is only about 20km from our location. We found each others light very fast and completed the QSO in AM within minutes even during the sunset. It was great to hear his modulation and i think it was my first voice QSO via light. I took a short video of his on-off beacon signal demodulated at my station. The loud noise is some 70cm APRS on the talkback frequency we had choosen.<\/p>\n
