Thought it was rather funny that the ARRL slide rule mixes units between metric and imperial - wavelength in meters and coil dimensions in inches.

When I was coming up (the 1960s) we seemed to use lots of air wound inductors. These days it would seem that toroid core inductors are far more common. Would you perhaps do a video comparing the advantages and disadvantages of the two types?

Excellent overview! How about using a NanoVNA?

Is it possible that an air-core coil can "saturate", so to speak??? Thanks for the great video!!!!

i just download this file, very useful,thanks

[@ssubaihi]

wonderful tools

[@CodeJeffo]

Would anyone know where to get those nice measurement clips? thanks

[@IMSAIGuy]

search for them, here is one: www.ebay.com/itm/312008567361?hash=item48a528ea41:g:HywAAOSwvApaFTNk

Thanks to you, sir I'm from Philippines ,, ❤️❤️❤️❤️ you help me out of my problem I want to build my own passive cross over

I used a nice GENRAD- Model 1658 ? LCR Bridge with Kelvin leads 1 kHz or 1 MHz test single ..and it had DC voltage in to bias and measure varactor diodes...for capacitance it could measure dissapation factor...and maybe Q in inductors...it maybe it is time to mail you a Xmas present....
