Jaz

S53DZ Bojan Naglic, JN76FC, Ljubljana, Slovenia
- my spare time interests: RF, C, asm, ARM, mountains, photo, billiards (not necessarily in this order)


A short story

Actually it has all begun with a few meter of wire, a crystal diode in a small glass tube,
a filter capacitor and headphones. And a great joy when a local broadcaster's sound was received.
Then there was an air coil, finding a proper tap on it and a rotary variable air capacitor,
finding some other on-air signals. Could well be that there was also a simple question like:
"What is the signal frequency?" or "What is this signal's strength?"
It was time to find some answers.


Home Laboratory

After a long time there were some hobby boxes on the table resulting from my DIY projects.
I thought it could be interesting also for those, coming by.


Lab

Some of my home-made instruments:
- RF signal generator, RF power meter, GPS-DO and OCXO 10MHz, Frequency counter.

Ducks

Sometimes with electronics it is the same as with these ducks standing on a thin ice - Lake Jasna, Feb 2008.


Projects on this web-site are well tested and are published in good will.
However, no responsibility can be made for making nor using them.


When will I manage to write an ideal code? Never, perhaps even not then.
