Homebrew 7-element Chebyshev Low Pass Filter for 7MHz - 2
The internals.
Amidon Powdered Iron Toroid cores and Silver Mica Capacitors
I made 3 of these, one for 3.5MHz, one for 7MHz (illustrated) and one for 14MHz.
They were built originally to work with my "Oner" transmitter as the latter has a rather ugly output signal, and needs to be well filtered before it can be allowed to pollute the amateur radio frequencies!
