Subtone unit available (CTCSS)

Development
For all the old equipment Dennis, PA4DEN has a beautiful little subtone-kit developed in 2008 with only a few components. This is a compleet mounted, build and tested kit, to put in your portofone or (mobile) tranciever. Any CTCSS tone which is used in Europe can be generated.

Application
Many relay stations now like to hear a region-tone (for your ears almost inaudible low-frequency) to open repaisstations and lower squelches (eg NL-map).
