Another amazing video!! Just curious... would we be able to measure input impedance using a similar U/I method by putting a small shunt in series and measuring a voltage drop across it using an oscilloscope, or is that method better suited for something else? (can't always be bothered with LTSpice) Thanks :) 9A3ICE
I was thinking the something similar, but went with convenience. I will have to put some more thought into it. In the past, I have simply relied upon Rin = R1//R2//BetaAC(re + Re) where re = 26/Ic in mA, and Re is the unbypassed portion of Re.
Thanks for another great video charlie, been really missing these.. i can't wait for the results.. 73s
You and me both Perian. Hopefully, I will get some time over the next week or so to start putting it all together.
Excellent video. Thanks Charlie.
Glad you enjoyed it
👍Perfectly explained and very helpful. Thanks for posting.
Thanks Steve. I'm pleased it was helpful.
By output you mean the signal at the collector correct? That would make sense.
Do you have any engineering academic degree to come up with all these electronic tech topics please ?

What is the alternative of those ferrite core impedance matching transformer???
You could go with an air-core, like a plastic washer or even a 3d printed core. Ashar Fahan VU2ESE has used those with some of his homebrew radios.
Very nice video de Yi1hxh rafat 73 from baghdad iraq
Thanks Rafat. I'll upload the receiver video tonight.
