Решавање проблема
If the straight line as shown to the right is displayed on CW Skimmer, adjust the IQ-Gain setting on HDSDR.
The straight line is displayed because of a sharp spike (a DC), if the noise floor is too low.
The IQ-Gain setting is displayed by <Options> and set “Output Channel Mode for RX” to “IF as I (Left) / Q (Right).” (pp. 8, 13, 18, 24)
САВЕТ: When adjusting the IQ-Gain setting
- The IQ-Gain should not be too high. After the straight line has disappeared, do not set the gain higher than that level.
- If the IQ-Gain is too high, CW Skimmer becomes easily saturated when receiving a strong signal. If CW Skimmer is saturated, lower the IQ-Gain or lower the input level on the IC-7760.
– Turn OFF the Preampлифиер.
– Turn ON the Attenuator function.
– Lower the RF gain.
– Turn ON the Digital Selector function.
