Welcome to the homepage of DL4YHF ! This page provides some tools (software by myself), hardware, and other information for radio amateurs, and some other not-radio-related stuff like the PIC programmer. If you are curious to know who DL4YHF is, look here. If you look carefully enough, and you are a human visitor (not a robot), you will also find my email address and other details there.

On this site you can find:

PC Software

  • Spectrum Lab - a tool for audio analysis, DSP, beacon logging, etc.
  • EbNaut recorder - configuration for SL to act as a 'scheduled recorder' for EbNaut (coherent BPSK)
  • WOLF GUI - a graphic user interface for Stewart Nelson's WOLF (Weak-signal Operation on Low Frequency)
  • Sound-Utilities - read from the soundcard's ADC and send to DAC
  • Audio I/O library - exchange audio in real time between different applications (also for audio streaming using winamp / oddcast)
  • CalcEd - a text editor which calculates with complex numbers !
  • CurveEdit - a primitive, graphical viewer / editor for array data ("curves")
  • PIC programmer - DL4YHF's WinPic for Win95+98+XP, uses LPT or COM1..4, and supports a variety of PIC microcontrollers.
  • RDF Calculator: for radio-direction finding, topographic map display, GPS track display, etc

PIC projects (firmware and documentation)


Recent changes:

  • almost once a month: New release of Spectrum Lab
  • March 2010: Website back at QSL.NET (which is back at full speed - thanks Scott), and farewell "freenet" which isn't free anymore.
  • January 2005: Website moved from QSL.NET to "freenet" due to bandwidth problems.
  • June 2004: WinPic updated, now supports "JDM PIC-programmer 2".

More Changes on this homepage..

There will be more in future. Check again ! Until then,
73 and hope to meet you on the amateur radio bands ..

P.S: If you sent an email to me, but didn't get a response, then read this . You may be one of the fellows whose email provider has put my email provider on a blacklist (thanks to some paranoid spam filter), so I have received your message but cannot reply !

Furthermore, don't expect a response from me if you keep bugging me with invitations from "mylife" etc. All messages from them are considered as spam here - in fact, all of them are deleted immediately by a filter which looks for names like "invite at mail dot mylife dot something". PLEASE STOP THOSE BUGGERS, and don't let some machine try to "invite" me to services which I'll never use (at least not in "my life"). Thanks.

Furthermore, if you have problems getting my software running under Vista or some 64-bit version of windows, good luck. Sorry I cannot help with that, last not least because I don't use them. For Spectrum Lab users, send your request / observations or strange errrors / questions through the Spectrum Lab User's group.

Neulich, in der Windows - Taskleiste ;-)
