Not 120k, 120 ohm from emitter to the 1Kohm potentiometer
Buzzer FTW!!! Looks like a fun project. I really need to make some time to do this sort of thing at the bench. Thanks for sharing.
brass is diamagnetic
Really nice work, good luck with your project,73s my friend, Scott M0KJZ
Nice work....nothing like a free running analogue VFO, Elegant and simple. 73 de VK2AOE
I fully agree, during this time I have been just focusing on analog VFOs
badass, man. excited to see that receiver. you might get better stability, or at least better repeatability, by using a custom PCB instead of strip board and "dead bug" soldering. they're so cheap these days, it's worth learning how to use KiCAD to make your own boards.
Altoid boxes for the win 👍
Very impressive
No idea what your doing but looks awesome
Great video . What gadget you got there ?
Hello from Brazil!!! 73,s de PY4ROE
do more turns, it could be that your meter scale are much bigger than the measured value, that leads to measurement errors. but if the people comments are right, brass being diamagnetic would decrease inductance.
It's probly radioactive.
it's a screw you can get from the store
Basically brass absorbs electromagnetic it's like a stealth equipment
That's the permeability of coil changing and basis for metal detectors.
Brass is diamagnetic, meaning it lessens the magnetic field. The is a long explanation somewhere but basically - atoms doing stuffs
Thank you for explaining that! I was like.. the answer is out there
Doesn't this imply if you desire to kill as much inductance as possible from your circuit you can just add diamagnetic elements to it to further the effect? This reminds me of Tesla US Patent 1,119,732 - Apparatus for Transmitting Electrical Energy, the extra coil has a diamagnetic rod going through it to the capacitor terminal. "The circuit comprises a coil A which is in close inductive relation with a primary C, and one end of which is connected to a ground-plate E, while its other end is led through a separate self-induction coil B and a metallic cylinder B' to the terminal D. The connection to the latter should always be made at, or near the center, in order to secure a symmetrical distribution of the current, as otherwise, when the frequency is very high and the flow of large volume, the performance of the apparatus might be impaired."
@@JenkoRun In my 5 years of studying electrical engineering I never came across anyone or anything mentioning that specific use case. I'll have another look into it, but it does appear like a sound idea!
Excellent job! I built a rig a few years ago using 'breadboard' and soldered the leads on the back side. It looks neat from the top, but the bottom is a mess and without a solid ground plane, like you have, it's a little unstable. This is a better method. Congrats!
Definitely subbed. --... ...--
Nice homebrew!
Greats work . Diagram please . Thanks
Good redio
im gonna call BS....that looks like a copper plate, or a metal plate of some sorts at the least...which means you created a massive short
Its a ground plane. You do not understand the RF side of electronics.
Nice nice 🎉❤
Beautiful build! There's nothing like the feeling you get when the radio you built with your own two hands springs to life. Keep up the good work, thanks for sharing - 73 - Rick - N3FJZ.
Nice video ! Did you put a filter at the output of the SI5351 to transform the square wave into a sine wave? 73 de F4LDY
Bravo! Congratulations. A superb example of homebrew construction. Pete N6QW
Thank you Pete! I am glad that the VFO worked and is so stable, VFO's are an art form just by themselves. 73s
Are you talking with aliens 👽
It does sound otherworldly!
