June 18th, 2018 This morning I had a look for DB0MFI, a new beacon on 1296.940 MHz in JN58HW. It is audible with 529 constantly via tropo and peaking 579 via aircraft scatter. The power is 5 W into a 4 times stacked big wheel antenna. In the afternoon I went for it on […]
June 3rd, 2018 As can be noticed now, the fears, many Microwavers would prefer to go to the HAM RADIO fair in Friedrichshafen, were overdone. It was a nice contest and in the 23 and 13 cm sections I worked more stations than in the last contests in May and March, as well as in […]
April 20th, 2018 The french beacon F5ZBM is on air again. I found it accidentally, when looking for other french beacons. It is at a new location in JN18MN near Paris transmitting on 1,296.8475 MHz. Nice to monitor it in Mainz via aircraft scatter over a distance of 406 km! The keying is in F1 […]
December 22nd, 2017 Tonight I monitored OZ7IGY on 2,320.930 MHz via aircraft scatter. It was nice to see other beacons appearing shortly in the waterfall diagram. From left to right: 2.320.900: DB0UX, JN48FX, 105 km, tropo 2,320.910: DB0XY, JN51EU, 263 km, aircraft scatter 2.320.920: DB0VC, JN54IF, 509 km, aircraft scatter 2,320.930: OZ7IGY, JN55WM, 670 km, […]
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 […]
August 17th, 2017 The whole morning I monitored EA2TZ/B in IN93BF on 1296.854 MHz over a distance of 1072 km, peaking up to 30 dB. The vertical profiles of 0:00 UTC from Paris and Bordeux showed an inversion at 1000 m altitude. F6DKW from Paris was booming here, but nothing could be heard of beacons […]
May 7th, 2017 After the unexpected good result in March on 13 cm, I had a special focus on this band in May contest. Last year I marked my new record in the number of stations worked on 23 cm, this year I improved the new record from March in worked stations on 13 cm. […]
If you are looking for prospective times, to be QRV on the VHF, UHF and SHF bands, you should consider the certain monthly trans-regional activity contests. On 23 cm and up it is useful, to arrange skeds in the ON4KST microwave chat and to make use of the latest Version of AirScout (by Frank, DL2ALF) […]
November 22nd, 2016 Today I configured the MKU 23 G4, I ordered from Michael in Friedrichshafen to perform a RX test. Via aircraft scatter it was no problem to receive the beacons OZ7IGY in JO55WM over 670 km and OK0EK in JN89VJ over 689 km. The sun noise is at a level of 6 dB. […]
Vortrag: “Reflexionen an Raumfahrzeugen” Andreas Imse, DJ5AR Wenn man das in den letzten Jahren auf den UKW-Bändern zu großer Verbreitung gelangte Aircraft Scatter weiterdenkt, gelangt man zwangsläufig zu Reflexionen an Raumfahrzeugen. Versuche, die ISS als Reflektor zu verwenden, waren vielfach erfolgreich, so dass Transatlantik-Verbindungen via ISS, aber auch Experimente mit kleineren Objekten in den Fokus […]
