Here you will find some hopefully useful information in future. Some links may not yet work, so please watch this page for changes. If you have any questions or suggestions, mail me.

• FM with the Icom IC-720A
  These are the modifications I did to my IC-720A shortwave TRX to enable it for FM operation on the 10m-band. It contains some aspects that may also be useful for modifying other transceivers.
• DB0ADF, the Automatic-Direction-Finder
  Some words about the remote controllable Doppler-direction finder station located at the QTH of our club station, DL0RB. It's not yet very useful, because it lacks a really good user interface. Suggestions are welcome.
• Here is a description of a RLC and impedance meter using the PC soundcard, and a rudimentary Linux-program with a text-based user interface. All you need externally is one reference resistor and an SPDT switch for calibration. The software is open source and will be put up here soon after some cleanups.
• Packet Radio and SSTV on the Toshiba Tecra 730XCDT with Linux
  Using the sound-card of this notebook, you can operate in packet radio and SSTV from portable without additional TNC or converter hardware. And even better, you don't need anything from Microsoft to do so. This page may be helpful for owners of other notebooks as well.
• MININEC, the antenna calculation program originally written in BASIC, has been ported to C by me (not only for UNIXes). I will however not yet put the source code here because I'm not aware of the legal issues about this fine piece of software.
  But I really would like to, so that some people can test it and compare the results to the BASIC program to find the bugs I possibly added. If it could be made open source, this could be a way to further improvements and expansions.
  Please tell me if you know about copyright issues or legal regulations to re-publish a modified MININEC source !
• Links to interesting pages
  Not only ham-radio related, but also other useful, entertaining or interesting stuff.
