is there a simple (or recommended) method to stop the DAB receiver chain for the
SI4685 chip when a DAB TUNE FREQUENCY command has been sent (and has been
accepted and is currently active) to reduce RF-Noise in a conventional FM-Receiver
Unit equipped with a DAB upgrade board (to keep interference with the original RF-Input
circuitry as low as possible) ?
E.g. Is it possible to just send another DAB TUNE FREQUENCY command with e.g.
an invalid DAB RF-Frequency to stop the receiver chain ?
We are just redesigning an already operational Add-On DAB-Board for old Tube-
Radios for 'modern' Type FM-Receivers (where the RF-noise from the DAB Board
disturbs the FM RF-Input when DAB receiving is active but not currently in use. For
reasons of fast change from external FM-Mode to Add-ON DAB we obviously do not want
to completely power down the DAB-Chip).
