MAIN SCREEN DESCRIPTION
Each settings type has it's own tab and differs from others in terms of Attack, Decay and Hang
time.
AGC parameters:
·
Slope – set the slope of the transfer characteristic.
·
At t ack – when a signal gets stronger, this value determines how quickly the AGC will
decrease gain.
·
Decay – when a signal gets weaker, this value determines how quickly the AGC will increase
gain.
·
Hang t ime – signal recovery time.
·
Threshold – AGC trigger threshold.
Def ault – reset AGC setting to the default level.
Press the Def ault button if you set wrong AGC values and don't like the result. Each AGC tab
has a Def ault button.
Digit al processing f ilt er's set t ings.
There you can find fine the settings of the receiver's digital processing filters.
DSP functions clears the signal from abnormal noises and crosstalk.
These are the standard functions:
·
ANF – Auto Notch filter, removes the carrier signals. This is a special adaptive filter, which
removes any periodical signals from the air in the RX filter band.
·
NR – Noise Reduction, removes the white noise. This is a special adaptive filter, which
removes any abnormal noises from the air in the RX filter band.
·
NB – Noise Blanker, removes impulse interference.
·
APF - Analog peak-filter for CW mode. Provides a more comfortable listening of the CW
signals by amplifying the CW signal in the center of the receive filter (triangle filter's AFC
(amplitude-frequency characteristic) in the filter bandpass).
