DARC Microwave Contest

The DLØGTH/p team had great fun on 5th and 6th June in the DARC Microwave Contest. We operated from DKØNA location in JO50TI again. We enjoyed very good rain scatter condx. Since we always try to improve our equipment DL2ALF designed a new switch box (see picture below) which enable to switch all transverters and antennas directly with Wintest band change key. Less chance for operators mistakes. Finally, we are also satisfied with the results achieved.

Almost final results


The Radio Society of Great Britain honers DL2ALF.

‘1962 Committee Cup – awarded for outstanding amateur development at VHF/UHF. Awarded this year to Frank Schmähling, DL2ALF for the outstanding development of AirScout software for aircraft scatter.’ See facebook.com

Congratulation to Frank for the great achievement.

Thuringia Ham Meeting

Radio amateurs of Thuringia met in Mühlhausen on 14th May. It was the first of its kind Ham radio meeting for more than two years. Unfortunately, the participation was rather poor. Maybe, some Hams were still concerned of COVID19 or just because the location was a bit remote for most regions. However, I enjoyed to meet some old friends as well as watching very interesting presentations.

70 cm FT8 Activity

70 cm FT8 activity is scheduled every 2nd Wednesday evening of the month. I participated the first time on 13th April. Since I did not use FT8 on 70 cm in the past a lot, I could log a lot of first contacts, in total 25 QSO. ODX was the QSO with John G3XDY almost 700 km. Not bad with  75W and single 16 element Yagi antenna and rather poor propagation conditions. Sure, I will check the 3rd Wednesday of the month when 23 cm activity in scheduled.

HRD Logbook upload to hrdlog.net

HamRadioDeluxe is a great ham radio software suite with a lot of dedicated tools and features. Its HRD Logbook has also capabilities to sync  with other databases including LOTW, eQSL but also http://hrdlog.net. I had some problems with hrdlog.net which was caused by blacklisting of one of their servers. It took me some time to debug but finally Mike VK4EIE provided the important info that data is uploaded to mail.hrdlog.net (instead of just hrdlog.net). It is not any email protocol used but just port 80 (html) for that purpose. For some reason mail.hrdlog.net was blacklisted and therefore caused upload fails. After mail.hrdlog.net was whitelisted the software worked perfect for the purpose.

Lessons learnt: In the good old days, hams were busy to fix problems with their transceivers or antennas. Today, we spend more time to fix software or Internet issues.

Nice Tropo ConDX on 13/14 January

Good tropo condx to UK on January 13th and 14th. Completed QSO >500km listed.

It was a great pleasure to participate the Marconi Memorial Contest on 2m in CW from home QTH in JO50NV. Operatung about 10 hours only, I was quite satisfied with 185 QSO. Conditions were not really great.

IARU Region 1 UHF/SHF/Microwave Contest

DL0GTH focused on 70cm during the contest which took place October 2-3. Unfortunately, some OP were not able to join the team resulting in no activity at DL0GTH on 23cm, 13cm, 9cm and 6cm bands. Nevertheless, our small team had a lot of fun in the contest. Congratulations to DR9A who have likely won the contest.

IARU Region 1 VHF Contest

DL0GTH participated the contest from Schneekopf in JO50JP on 4th/5th September with much smaller than usual equipment. Nevertheless, the results achieved were much better than anticipated with such reduced equipment: 1086 QSO and >410000 points. Looking forward now to the October UHF/SHF/Microwave Contest.

July VHF/UHF/SHF Contest

Even, I participated a few hours only, I am quite satisfied with the results. No skeds, no airplane scatter software use.
144 MHz: 101 QSO, ODX IQ5NN 823 km
432 MHz: 20 QSO, ODX OM6A 583 km
1296 MHz: 10 QSO, ODX DG2GR 192 km
Now, I am looking forward to September IARU-Region 1 VHF Contest. DL0GTH will be QRV again from JO50JP in multi OP mode.

Returning to normal life

Fortunately, new Covid-19 infections went down significantly, shops and restaurants are open again and I am looking forward for some ham radio events. I also got my second shot of vaccine and feel much more safe now. Likely, I will participate July VHF/UHF contest in Single OP category still. But I am confident that DL0GTH will operate as Multi OP station in IARU-Region-1-VHF contest. CU on the air.

May VHF/UHF Contest from Home

Since multi operator contesting is still restricted by Corona pandemic rules, DL0GTH was not active and I made some QSO on 2m, 70cm and 23cm bands from home. A few hours only, also because there was not much activity and poor condx. The contest weekends are almost the only chance for some QSO in SSB/CW because outside of contests there is more activity in digital modes.
