My Blog

Fascinated by amateur radio operation at the local club station DL0DPM (located at the comunication museum in Frankfurt), I was taking an entry-leve amateur radio course in 2006. I've been licensed since autumn 2007 aged thirteen under DO3HPR. In December 2011, I passed the Advanced Licence (CEPT licence / HAREC) and got my present Callsign DK3CW. As I started to be on the bands, I've only had an Yaesu FT-817ND with 5 Watts QRP feeding an end-fed longwire antenna about 35 metres long and 10 m AGL (141m ASL). Antenna is still the same, but the main rig is now an Yaesu FT-100.

With passion for mountaineering and cycling (HF/VHF/UHF(SHF equipped bicycle), I enjoy portable QRP activities and activations (SOTA, IOTA, Lighthouse). I'm 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-III, Automatic Link Establishment (MIL-STD-188-141 and MIL-STD-188-110) , APRS, Packet radio, D-STAR DV (via D-RATS, see below) ARDOP. Furthermore, I'm testing other HF E-Mail Modes like jPSK or RFSM-2400/8000.


Replacing antennas at the UHF Repeater site DB0VE and preparing for HAMNET (2.3/5.8 GHz)

As a participant of SOTA (Summits on the Air) and GMA (German Mountain Award), the FT-817ND accompanies me during hiking, climbing and cycling to German, Austrian and British mountains. Another passion are Digital VHF/UHF Modes. I began using 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. Later on I added APCO P25, DMR (Digital Mobile Radio), TETRA and SystemFusion. Since 2010, it became my passion to take part 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 am organizing Foxhunting events or do foxhunting my self. I used to be a member of the ARDF unit of the DARC district Hessen. Also I was responsible for emergency communications at my local club (Emergency Communication Representative).

Since 2013, I am programming ham radio scripts in variouse programming languages for amateur radio purposes as well as using and collaborating in building the 2.3 GHz / 5.7 GHz european HAMNET as a quite modern field of amateur radio.

Also member of:

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 classical guitar...
