Microwave Contest June 22

This time i was able to join the team on Hirtstein in JO60OM. It was planned to do CW Fieldday and Microwave 23 + 13cm. For 23cm we took the rig of Henrik, DG0LFF. For 13cm new masthead transverter with 75W PA was just finished. In the last moment i took the 1m mesh dish with me as well as my old 9cm transverter with 5W PA and a patch antenna as well as my 6cm transverter on tripod. Fred, DH5FS brought the 10GHz station. I also took my laser station for some try with DM1LGF and DL3ARM.
We mounted two mast. One with 2x20ele for 23cm on top and the 1m dish with the transverter below. Only some meters above ground and to be turned by hand we mounted the patch for 9cm and the transverter. The 6cm transverter did stay on the tripod on ground level. 3cm was located on the second mast.
23cm was pretty good and also the new 13cm rig did a good job without any issues. Even on 9cm quite some QSO were done and even on 6cm there was some success although the time for those trials was limited.
Saturday evening i tried to establish lightwave contact with DM1LGF and DL3ARM. Unfortunately the sight was very bad (a lot of dust) and it was not possible to see the horizon. Therefore the 2 attempts did fail for this time although we spent a lot of time to find the correct direction.

Results:
23cm 71QSO 17000p
13cm 29QSO 6900p
9cm 8QSO 980p
6cm 5QSO 480p
3cm 7QSO 800p

22/05 VUS

Some participation in the May VUS contest Saturday night and Sunday. Worked from home on 70cm and 23cm. Conditions were quite ok but few station calling cq.

July 21 VUS contest

During the time i was qrv i experienced very low participation from DL. Activity from OK was quite good. Some nice AP scatter QSO arranged via ON4KST chat but also random QSO. The SDR really helps to find the people when turning the antenna. Average of 270km/QSO on 70cm and 220km/QSO on 23cm are quite ok for me for operating from home.

Saturday evening 70cm. Rig HiQSDR+Iceni Transverter, 50W, 15ele.
27 QSO 7300p, ODX S59DGO, 610km.

Rig HiQSDR+MKU13G3, 100W, 36ele.
25 QSO 5500p, ODX S50G, 560km.

And i almost forgot: 1 QSO on 3cm with OK2A ;) Rig: FT790R2, Transverter, 10W, 40cm offset dish and W1GHZ feed.

DUR June 2021

17 QSO on 23cm and 2 on 10GHz. Quite good activity on 23cm due to ongoing Alpe-Adria Contest.

2021 June NAC 70cm

Rig: HiQSDR, Iceni Transverter, 50W, HA8ET LNA, 15ele
Result: 13QSO, 5900p, ODX SM6VTZ 820km

I drilled some additional holes into the boom of an old 21 Tonna fragment in order to mount the mast clamp. Together with a 2nd segment this gave 15ele with some suboptimal clamp mounting close to one of the directors. But better than my 5ele lightweight i estimated. It turned out to be right.
Some of the OZ stations where easy to work. OZ1DLD/P even in SSB. Outstanding signal from SM7DTE. ODX was again SM7VTZ with a rather short AP reflection this time. But i was happy to work him with my 50W qrp signal. An average of 424km per QSO is surprisingly good.

my 70cm “transverter in a box” mess. But it does the job.

IARU June contest 2021

Because of some Covid restrictions still in place in DL there was the decission to remove the nigh time from the contest period in Germany. For me this was a very unfortunate decission since this is usually the only time where i can operate without interruptions or other assignments.
In the afternoon there was quite some RS condition. I tried to find some QSO partner on 6cm but did not succeed. I heard DB0FGB (JO50), DB0NCO (JN59) and a OK station calling. The OK station did not come back to my call and i was not lucky in the ON4KST chat.

Then i switched to 10GHz. Usually i am limited to direction south because of problems moving the dish through the upper roof window. This time i managed to put the little plastic dish outside to work some station to the north. At least DF0YY made it to the log this way.

Rig 3cm: FT-817, old transverter, 10W, 35cm dish with W1GHZ dualband horn
Result 3cm: 7QSO, 660p, ODX OK1FPR 200km

Later i tried 23cm. 10pm local time was already close. But i was not sure if i would be able to do some more QSO on sunday. So i decided to give some points to others outside DL at least and continued for a while. In the end i did not switch on on sunday again.

March 21 IARU contest

Since there were still heavy covid restrictions and no chance to sleep somewhere we decided not to go to JO60OM for multi-Op. I was planning to be part time qrv from home in JO61UC. Since i completed my test-setup of the Iceni 70cm transverter i was able to operate 3 bands, 2m,70cm,23cm. More bands are not possible because the mast is too short and 13cm is not ready yet.
Despite i thought different my main operating time was saturday afternoon. I started with 70cm because i was curious for this band that i never operated from home before. It started very slow, almost nobody qrv in the beginning. During the contest some nice QSO came on top with S59P and S57M. Keep in mind that this is only 5ele and 50watts.

I later changed to 23cm and did some qso there. On 23cm it is a bit easier since i have 36ele and 100W. Many thanks to DL3IAS and DL3IAE for the ODX QSO via AS.

2m i started in the evening after the kids were sleeping. Unfortunately the conditions were very poor and i ended up with frustrating 20 QSO.

Overall the result was a bit disappointing with the highlights of the 70/23 ODX QSO and the fact that the 70cm transverter was working fine.
