DB0TUD as Beacon #60 on 23 cm

March, 23rd, 2018

With the dish bearing eastwards tonight I mentioned the trace of a signal appearing and disappearing close to the local beacon of DF5AY. A quick look at beaconspot.eu told me, DB0TUD should be around there.

I copied DB0TUD in summer 2017 via rain scatter on 13 cm, but never on 23 cm so far.

Curious about the source of the signal after catching a “…UA…”  I turned the dish to Dresden and monitored the frequency for about an hour. The mostly short appearences of the signal correlated with planes crossing the path to DB0TUD in JO61UA. After an hour or more I got a reflection containing some CW : ” …0TUD JO61…”.

A digital evening on 23 cm

October 25th, 2017

There was nice activity in JT9F on 23 cm tonight. It seems this mode works fine with aircraft scatter. I first worked Conrad, PA5Y in JO21VO (255 km) and Sam, G4DDK in JO02VO (540 km) via Tropo. Then logged a QSO with Neil, G4BRK in IO91HP using mainly aircraft scatter. In another test I decoded Neil, G4DBN in IO93NR (756 km) by reflections on airplanes. PA0JME and ON5KTO were calling CQ, but not replying to my calls. Instead I worked John, G4BAO in JO02cg (619 km) in an (too) easy way.

Worked stations in green, the heard ones in blue.

Anyway, it was a promising and exiting evening!

Addendum October 27th, 2017

Yesterday I logged Rien, PA0JME, Wim, ON5KTO and John, G4ZTR, also in JT9F on 23 cm.

Chatting with John, G4BAO, last night, I learned, he recently initiated a “Digifest” on the microwave bands every Wednesday. This resulted in what happened two days ago. In my opinion it´s a very good idea to have such an activity evening beside the regular contests.

DL65DARC will be QRV on 23 and 13 cm

June 15th, 2015

From Monday, June 22nd to Wednesday, June 24th I will be QRV during the evenings on 23 cm and 13 cm using the special event callsign DL65DARC.
Skeds (aircraft scatter, tropo) are welcome via ON4KST, Facebook or email.

Rig will be a 3 m dish with 150 W on 23 cm and 75 W on 13 cm. The QTH locator is JN49CV. SSB, CW and WSJT modes are suitable. Operation on relays is not intended.

If I find some spare time, I will be QRV on June 25th, 26th and 28th as well.

On Saturday, June 27th, you can meet me in Friedrichshafen.

 

Back on air again!

January 19th, 2012

After being qrt by family and business reasons for nearly twenty years, I started in July 2011 in activating my irish call sign EI8HH on 50 MHz. Since January 2012 I am qrv again as DJ5AR from my QTH in Mainz.

The way working on the microwave bands has changed. No more CQs for hours and hours, but a fine chat at ON4KSTs server to make skeds on the bands wich provides much more efficiency than the way, we tried to make QSOs twenty years ago. A SDR makes it possible to display a spectrum of the band on the screen in a waterfall diagram. What a huge comfort compared to the old times. So it is no problem anymore to find somebody for a sked on 23 or 13 cm. Soon after setting up the old equipment for 1296 MHz I managed to work a couple of new squares and had my first QSO ever over the alps to Italy. It was amazing to hear the strong signal of IK3GHY with my 1.2 m dish.
