  // Unfortunately bandwidth is conflated  with mode, this is probably
  // because Icom do  the same. So we have to  care about bandwidth if
  // we want  to set  mode otherwise we  will end up  setting unwanted
  // bandwidths every time we change mode.  The best we can do via the
  // Hamlib API is to request the  normal option for the mode and hope
  // that an appropriate filter is selected.  Also ensure that mode is
  // only set is absolutely necessary.  On Icoms (and probably others)
  // the filter is  selected by number without checking  the actual BW
  // so unless the  "normal" defaults are set on the  rig we won't get
  // desirable results.
  // Leider wird Bandbreite mit Betriebsmodus verwechselt, vermutlich
  // weil Icom das genauso handhabt. Daher müssen wir die Bandbreite
  // berücksichtigen, wenn wir den Betriebsmodus einstellen wollen,
  // sonst legen wir jedes Mal unerwünschte Bandbreiten fest.
  // Über die Hamlib-API können wir bestenfalls die normale Option für
  // den Betriebsmodus anfordern und hoffen, dass ein geeigneter Filter
  // ausgewählt wird. Außerdem muss sichergestellt werden, dass der
  // Betriebsmodus nur dann eingestellt wird, wenn es unbedingt notwendig ist.
  // Bei Icom-Geräten (und wahrscheinlich auch anderen) wird der Filter anhand
  // der Nummer ausgewählt, ohne die tatsächliche Bandbreite zu prüfen.
  // Wenn also nicht die Standardeinstellungen am Gerät festgelegt sind,
  // erhalten wir nicht die gewünschten Ergebnisse.
  // As  an ultimate  workaround make  sure  the user  always has  the
  // option to skip mode setting altogether.
  // Als ultimative Lösung sollte sichergestellt werden, dass der Benutzer
  // immer die Option hat, die Moduseinstellung komplett zu überspringen.
