Hello my name is Jakob. I am 19 years old and a ham radio operator since fall 2007 (CEPT Novice licence). In December 2011 I passed the Advanced Licence (CEPT licence / HAREC). My previous / former callsign was DO3HPR. Actually my working conditions are a Yaesu FT-817ND with only 5 Watts QRP and a longwire antenna, which is about 40 metres long and 10 metres over the ground (141m ASL). The Location is near the inner city of Frankfurt on the river Main in Germany. Basically I am active with QRP and within portable activations (SOTA,IOTA,Lighthouse,WFF etc.) I am interested not only in the classical radiophony and telegraphy but also in qrp digital modes like WSPR (Weak Signal Propagation Reporter), JT65, JT9 or ROS. Mainly, I am working and testing digital EmComm operation via HF using WinLink 2000 Network with different Modes like WINMOR (Winlink Mail over Radio), PACTOR I-II, Automatic Link Establishment (MIL-STD-188-141 and MIL-STD-188-110) , APRS, Packet radio, D-STAR DV (via D-RATS, see below). Also testing other HF E-Mail Modes like jPSK or RFSM-2400/8000. Certainly I'm also interested in the more popular modes like (Q)BPSK31/62/125, RTTY (F2B), MT63, OLIVIA, CONTESTIA, OPERA etc.

Furthermore, I participate at SOTA (Summits on the Air), GMA (German Mountain Award) and WFF (World Flora and Fauna) also with my FT-817 on German and Austrian mountains and nature park areas. Later on, I will pass the CW additional test to work in CW mode in nonforeign holiday QTHs, which need this additional certification. In addition I'm interested in Digital UKW Modes like Packet Radio (1k2 and 9k6) and D-STAR. Specially on D-STAR and packet radio, I use the programm D-RATS. Its a data communication tool based on the D-RATS Digital Voice (DV) protocol and ARQ-protocol which offers low speed data transfer. Since 2010, it becomes my passion to work in SSB and Digital Contests on Shortwave (e.g. Fielday, CQWWDX, WAG, WAE, Ukrainian DX contest, Educational contest, SARTG, PACC, UBA, QSO Party, XMAS, DARC 10m Contest, ARRL 10m Contest ...), but also in a few VHF / UHF contests. Seldom, I participate on foxhunting activities. This is why, I am a member of the ARDF unit of the DARC district Hessen. Also I am responsible for emergency communications at my local club (Emergency Communication Representative)

  • DP6T Contest Group Wittgenborn (WAG contest, CQWWDX contest, ARRL 10m Contest, IARU HF, CQ WPX, DARC 10m ...)

Furthermore I´m interested in natural sciences, especially astrophysics and botanic but also in the humanities muchly philosophy. Some of my freetime activities are hiking (in combination with SOTA and GMA), climbing, Wing Tsun-Kung Fu, programming, Wikipedia -author (e.g. ham radio articles), playing the calssical guitar...
