[Elecraft] Width of AM filter

[Ignacy]

Hoping for a 8 MHz LC filter with a BW of 13 KHz and good mirror rejection is like hoping to run a car with a few AA batteries.
A similar idea: the inside of the radio can be "hardened" by applying 117V to random circuits for a second!


I hope I am not stepping on any toes - but I found someone who had designed a 13Khz +/- filter with some toroids and caps - incl variables to adjust and built two and they work great in main KRX3 -
just confirmed again they give nice fidelity on AM  - and I can hear the 6khz filter click in when I reduce BW to 3...  low cost - fair bit of labour :-)
