ELECALC.ZIP About the programs: Findval is a simple menu driven program for finding the values of resistors and capacitors from the sometimes cryptic codes on them. the Resistor section allows you to find the value of a resistor from the color code including components with Silver and Gold multiplier Bands. You will get a screen with the highest, nominal, and lowest allowable value according to the tolerance band selected. You may also give Findval a resistance 10 ohms or greater and a tolerance and Findval will tell you the color code for that resistance. The Capacitor Section of Findval is for the conversion of codes often found on Disk type capacitors (ie: 240K = 24pF +/-10%). Ohmslaw is a basic calculator for finding resistance (R), current (I), voltage (E), and power (watts). The power section allows you to calculate power by either I^2*R formula, or, the I*E*Efficiency(%) (FCC indirect method) formula for Radio. SWR is a calculator for finding the Standing Wave Ratio from measured foward and reflected power (in watts). Wavelen is a calculator for finding whole, half, and quarter wavelength in Meters, Feet, and Inches, from a Radio Frequency entered in Megahertz. This should be useful to those designing antennas to find the length of wire to use in any common unit of measurement. All of the programs are menu driven and self-explanatory and easy to use, Just follow the prompts and you got it! REGISTRATION: If you like this program, please send $10.00 per copy for registration. Be sure to mention it is for the ELECALC package as I now have several software packages in circulation. As a registered user, you will be entitled to free upgrades to this package via The Boonie BBS as I produce them.
