PI7RMD is on air for quite a while now on 13 cm. I already spotted it on May 3rd, 2020. Looking at the entry at beaconspot.uk wondered, why no one else sent any spots. So I had a look for it today and got some nice reflections via aircraft scatter.
PI7RMD is located in JO31AD, using a double quad antenna beaming 270° with 5W ERP. It is keying in A1A on 2320.8948 MHz (nominal 2320.895 MHz).
Tonight I met Salvo, DK3SE, in the ON4KST chat. Salvo recently became QRV again on 13 cm. He uses a 1.8 m dish and has about 50 W at the feed. As his location is on the southern slopes of the Black Forrest, our direct path is blocked by solid rock. Even aircraft scatter is very hard to perform. So we tried to find a reflective point at the mountain range of the Alps, but that was not very satisfying as well. Next step was to try side scatter on airplanes to the east of the Black Forrest.
We tried on a couple of planes and, as expected, on the ones, we saw the same side of the body, we received strong reflections. So we learnt, in side scatter the orientation of the plane matters! This is in opposite to the usual aircraft scatter, where the planes just have to be on the path and the bottom side of the aircraft is used as reflector.
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.
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.
