- 30 m Band Direct Conversion Receiver
- The direct conversion receiver described consists of only a bandpass filter, mixer IC, VFO and audio filter. With only 22 parts, this simple circuit should take a few hours at the weekend to construct.

- A 3.5MHz Receiver for SSB and CW
- Homemade receiver for 80 meters band. The receiver works very well (in fact better than some of its successors), especially the AGC makes listening to 80m QSOs a real pleasure. Sensitivity is not cutting-edge, but on a full-size short-wave antenna it is by fare sensitive enough.

- Blocking Dynamic Range in Receivers
- An explanation of the different procedures and definitions that are commonly used for blocking dynamic range (BDR) measurements. Dynamic range in general is the ratio between the weakest signal a system can handle and the strongest signal the same system can handle simultaneously without an operator switching attenuators or turning volume potentiometers

- SDR Receiver using a Tube
- The build was an experiment to see if a tube receiver could be stable enough to receive digital shortwave radio broadcasts.
The tube acts as both an oscillator and mixer, so the receiver is a type of direct conversion receiver.
