| Should I tune for Resistance or Impedence? | KT8DX | 1 day, 2 hours ago |
| If your head is swimming, it is likely that you aren't a math genius that can easily understand numbers well enough to tune by them. Many folks think in terms of pictures, so graphical representations are more understandable. You may want to investigate other analyzers to see if there is something with an display you understand. |

| Should I tune for Resistance or Impedence? | KT8DX | 5 days, 4 hours ago |
| A Smith Chart is a graphical representation of impedance that is more intuitive than R +/- jX If you use a Smith Chart normalized to 50 ohms, the closer you get to the center the better the SWR. |

| "Error in Sound Input" Message | Goldingen81 | 1 week, 1 day ago |
| This may be a memory access violation https://wsjtx.groups.io/g/main/topic/recovery_from_error_in_sound/69952737 You may want to try JTDX and see if the problem persists. https://sourceforge.net/projects/jtdx/ Ferrite cores are significantly more effective at HF if 10 to 15 turns are wrapped around the toroid.
