UINT
Kilohertz);
Parameters
Mode

TunerID
Index of the station to be set, beginning at zero for the first station.
Kilohertz
The frequency (in kilohertz) that the station is to be set to. For AM,

UINT __stdcall RadcapGetRSSI
(
enum RadcapTunerType Mode,
int
TunerID);
Parameters
Mode
Specifies AM or FM tuner.
TunerID
Index of the station to be read, beginning at zero for the first
station.
Return values
If the function succeeds the return value is the received signal strength
indicator.
If the function fails, the return value is zero. To get extended error

Comments
The received signal strength indicator is not available on the original
2-channel FM Radcap cards. This function will succeed with those cards
but will always return 0.
The received signal strength indicator is a relative indication only and
should not be taken as an absolute measurement of signal strength.
This function will fail if the monitor program (Tuner.exe) is running.
