Using the mini Ring Core Calculator application will make it easier for amateur radio enthusiasts to calculate inductors, numbers of turns, wire lengths, and many other factors related to both powdered iron and ferrite toroids. The program will also enable you to calculate parameters for air wound coils used in the construction of linear amplifiers, low pass filters and antenna matching units.

Decrypt the color code of fixed resistors. The marking starts with the band nearest to one end of the resistor. A wider band is always the last one. Encoded are the resistance in Ohm, indicated by 2 or 3 bands and the multiplier, the tolerance in % and in certain cases the temperature coefficient. The temperature coefficient is the last wider band in the 6 band code. It's given in ppm/K.

You need a certain inductance and looking for the corresponding number of turns. Well, looking for the AL-Value in a table and found it. But what about the formula? Not found or if you did, which units to use? Is a T50-2 red or yellow? This program has all these answers and even more.

Beacon -light- is just a simple beacon monitoring program. All beacons are controlled precisely by GPS. That’s why the PC-Clock has to be set precisely as well. In the bottom of the window select the band to be monitored (the arrow keys can be used). The actual active beacon is shown with lime background.
