Born in 1972, i´m a Radio Amateur since 1988.

My first Callsign was DG8MFN (former Class C, no HF, no CW, only 75W PEP) , then DH0MBJ (former Class A).

Since December 1990: DL8MFU
Additionally i registered a "Training-Call", so since February 2nd 2015 i also hold DN1MFU.

Also since April 20th 2016 KG5MZT

My DOK is C18.

My main interests are: Shortwave, 6 and 4 meters, 23 cm, SDR-Technology, ADS-B, Hamnet and Radio Direction Finding.

QSL Policy:

I still prefer Paper QSL but i also upload all QSOs to eQSL.cc, QRZ.com and LoTW.
Paper QSLs will be sent via bureau. Direct QSLs will be answered direct. This service is for free! You don´t need to send me IRCs, USD or Paypal!

 

 

On Feb 22 2016, my daughter Franziska successfully reached her Class E License DO2FH. Mni Congrats!

  • This is here my latest Setup: Do VoIP with my FRITZ!Box and a CISCO-Phone over HAMNET:


    Very awful!
    In future you can use the Phone-Number 315380613382 (aka DL8MFU - see: https://www.oe2wnl.at/calltodtmf-voip.php ) to reach me directly in my shack. It´s also good for skedding a QSO  yes.

As you can see, my special interest is Radio Direction Finding. Therefore i use a stationary Doppler Direction Finder from Germany´s No. 1 Direction-Finding-Company "Rohde & Schwarz" named PA555:

I wrote a special Application to visualize all Bearing Parameters in a georeferenced Map based on MapWindows:

If you`re interested in this solution, then drop me a mail.

Started in 1986 as a SWL. Here are some of my early QSL-Cards of Radio Stations around the world. Some of them are QRT now:

 

Radio Sofia - Bulgaria

 

Stimme der DDR (Voice of the German Democratic Republic)

 

Radio Nacional Do Brasil

 

Radio Kiev (former USSR)

 

Deutsche Welle (Federal Republic of Germany)

 

A letter of Radio Moscow dated on April 10th 1987

 

My DX-Club membership Card from Radio Moscow:

 

 

QSL Card from VOA (Voice of America) in 1987 - The Skyline of New York:

Then in 1987 i started to learn for the Radio Amateur Exam Former Class C. This here was my firs QSL-Card:

 

 

On December 20th 1988 i had my very first QSO with DJ4OP (sk) - my Mentor - without him i would never got in touch with HAM Radio. Thank you Werner!

And here are some early QSLs back from the late 1980s and early 1990s:

Y24SK (former German Democratic Republic)

 

 

 

 

 

The QSL card of my employer from the early 1990s:

 

 

OK1VTF from former Czechoslovakia

 

 

And finally some newer (and more exotic) QSLs:

 

 

 

 

 

 

 

 

 

 

 

.... and everything started in 1972 with this SABA Konstanz:

This Radio still exists!
