Mar 2, 2015 · Das LC-Meter von AADE, das auch über den Shop der Zeitschrift FUNKAMATEUR erhältlich war, leistet bei mir im Shack unschätzbare Dienste. 01 pF to 10 uF" The morse code version ELSIE Meter Kit (which also has serial port interface, and LED option, and measures frequency), measures even higher L: "Capacitance: ~ 1 pF to ~ 1 uF Inductance: 1 uH to Re: [Elecraft] AADE LC meter for ham radio Stephanie Maks; Re: [Elecraft] AADE LC meter for ham radio Vic K2VCO; Re: [Elecraft] AADE LC meter for ham radio Stephanie Maks; Re: [Elecraft] AADE LC meter for ham radio Tom Hammond; Re: [Elecraft] AADE LC meter for ham radio Alexandra Carter; RE: [Elecraft] AADE LC meter for ham rad Ron D'Eau Claire Nov 1, 2024 · I have three different model LC meters for measuring the capacitance and inductance of parts. I am selling them for about 50% of new price. One thing I noticed as I was going through the parts list is that the design consisted of a pair of 2 capacitors, C2a and C2b, of which the total capacitance is vital to the operation of LCR Meter - 2024 Professional 10KHz LCR Meter Tweezer with 0. The case looks custom cut plastic with engravings; sadly, some of them are wrong and misleading, like the one on the power jack, saying 9V AC where, upon In December/January I had offered a kit that allowed measuring varactors on the AADE LC meter. [To compose the Franclin oscillator and MPU ] A certain Eastern Europian electronics engineer found this idea in along 1990’s. Mar 27, 2017 · AADE LC Meter: AT26 Crystal Capacitance Fixture Crystals (or resonators) in AT26 packages have vanishingly small capacitances, so I conjured a little fixture for my AADE L/C Meter IIB (*) that holds them securely under little fingers snipped from an EMI shield: Mar 22, 2021 · A basic digital multimeter (DMM) is usually the first measurement tool the aspiring electronics tinkerer buys. Here is a link: The LC Meter typically creates freq. From the odd test frequencies I am guessing it is a clone of the AADE LC IIB meter: I bought an LC meter kit from AADE. It seems to Description: The L/C Meter IIB is a hand-held, digital inductance / capacitance meter with a four digit display, featuring automatic ranging and self-calibration. e. I used it quite a bit while building my K1 and K2, to verify the values of some of the hard-to-read caps, and verify the values of the toroids I wire on T44-6 toroids. They each have their place but the AADE is more suitable for measuring radio L and C. Important note: I don't have the source code to this program, and I have no relationship with AADE or Neil Hecht's estate (besides being a very satisfied customer of his handheld L/C meter). One of the most accurate and widely acclaimed was designed and sold by Neil Hecht and his company AADE (Almost All Digital Electronics). If you are interested, please check out the links below.
