Thanks for sharing this wonderful inexpensive tool. No, it won't replace my Wavetek model 112 (from 1967), but you could still use it for a lot of things. If you're fussy, you can put 10 turn precision pots on it and better filter caps and resistors. Looks good enough to test components with. Hook up two to an audio amp for cool sounds! I wonder how easy it would be to make a circuit to automatically sweep a band of frequencies? Have a great day!
Hey friend ./ If you ..aveal qd82+ universal board for split type / can it be used with ref inverter...?..... .iam looking for vloger ..for that but. All split type inverter explain .....your explain ..waiting for that. /......if you. ..aveal this. ..
Before 40 years the quality of the output signal was questionable (XR2206). Today it is totally unacceptable. The sine wave looks to me clipped asymmetrically (the top portion clipped) and the amplitude at the upper band it is reduced considerably . Use the FFT function of your oscilloscope and you will see some harmonics (sine way signal)
best regards i think the chip is still acceptable. when there is price competition to success the market, then the quality is compromised. in this kit, most of the components are out of tolerance. in upcoming session, I will try to debug it. as its 100K potentiometer is just 81K ohms. resistors are also out of limits. it is my idea, that the quality of external components is main element in this bug. i will check the signal parameters, for distortion, flatness, and stability
@@HaseebElectronics I couldn't see the values of the components. The circuit is known from the past BUT needs at least 1% tolerance resistances and the best quality capacitors (again 5% max tolerance). Thees quality components (the film capacitors) cost MUCH
@@gamiwv yes sir you are right this quality is the biggest point in market competition. companies reduce quality to decrease price for hunting customers by their lowest price offers
@@HaseebElectronics Thank You Very Much for your kind and quick response, we all know that you are a very responsible and highly knowledgeable person and we learn lot from you, Thank You Very Much Sir
