In these pages you will find some material related to my amateur radio activity; IN3OTD is the call sign assigned to my amateur station in Italy.
To me, being a ham means mostly experimenting with radio-related electronics circuits and devices and I hope that the material you will find here will be useful also for your projects.
This new version of glfer SW spectrum analyzer was updated to use GTK+ 2.0 and has some new additional featureas added, like a new spectral estimator and several spectrum averaging modes. Moreover the CPU load has been greatly reduced, compared to the previous versions.
Version 0.4.2 allows to select any device in /dev as the control device for the transmitter.
There are several (overlapping) sections, where I add new material every now and then, when I find something I think could be of interest also to other hams:
- For the homebrewers, the schematics area with some of the circuits I have built
- Some programs I have developed trying to solve some common design problems. Amongst them, selecting the best parallel and series combination for a given resistance value, designing coils and variometers and single turn loops, compute the inductance of arbitrary coils systems with fasthenry, design minimum-loss bandpass filters, rotary encoders, and so on...
- Of course, there is also the pictures page, with my antenna and its variometer for the 137 kHz band and many others
