int HAMLIB_API rig_set_split_freq	(	RIG *	rig,
		vfo_t	vfo,
		freq_t	tx_freq
	)

set the split frequencies

Parameters:

	rig	The rig handle
	vfo	The target VFO
	tx_freq	The transmit split frequency to set to

Sets the split(TX) frequency.

Returns:: RIG_OK if the operation has been sucessful, otherwise a negative value if an error occured (in which case, cause is set appropriately).
