  • Jul 19, 2019 · Translating High Pass Filter Design Considerations to Simulation Successes. Building the circuit for a high pass filter might be the first step in moving forward with a design needing one, however, ensuring your high pass filter works as needed and is accurately modeled is just as beneficial. Adding a 160M Band pass filter to the 'Snake' Jeff VE1ZAC. I live pretty close to two AM transmitters, and one of them is on 920 KHz. This puts the 2 nd harmonic right in the middle of the 160M CW section at 1840 kHz. And, this thing is strong! It uses up 30 kHz on either side of 1840 kHz.
  • While transceivers that cover 160m have some kind of L/C front end, I would say about half need a 160m high-pass filter to keep from being overload by AM broadcast signals at my QTH. ADC overload with today's direct sampling radios isn't an issue of 100 S9 + 30 signals randomly adding up in phase.Search: W7iuv Loop.
