RF - Antenna switch and RF attenuation

If an antenna switch is installed for multiple antennas, they can be switched and their RF attenuation set from here.

• RF Attenuation
• Antenna Switch

WFO - Waterfall Only Connections

The waterfall only (no sound channel) connections. The button text starts out as "WFO" and changes depending on the frequency.

• Waterfall Ceiling (Autoscale button sets level)
• Waterfall Floor (Autoscale button sets level)
• Waterfall Rate (Slow Dev button to slow rate)
• Spectrum Delta
• Aperture Auto Mode (enable, type)
• Spec RF Passband Marker (enable)
• Timestamps (enable, set timezone)
• Waterfall FFT Type

Audio

Audio controls. Sets the volume, allows noise blanker and filter selections, the squelch level using the sliders and the head pre-record time/tail length, compression enable/disable and overload mute filter.

• Noise
• Volume, De-Emphasis
• Pan
• Squelch
• Noise Blanker (set Defaults button)
• Noise Filter (set Defaults button)
• Noise Blanker Test

AGC - Automatic Gain Control

Enable/disable the Automatic Gain function. Set manual gain, threshold, slope and decay time with the sliders. Return to default settings.

• Manual Gain
• Threshold
• Threshold CW
• Slope
• Decay

User - User Information

Shows connected user information for each receive SDR channel, RX0 through RX4.

• RX0
• RX1
• RX2
• RX4
• Client user Name/callsign

Stat - Statistics

Displays various statistics of interest such as uptime, waterfall refresh rate and audio bandwidth, CPU speed and utilization as well as other network usage statistics. Also has a few links to the KiwiSDR Forum, Chat, etc.

• Some KiwiSDR Links
• KiwiSDR Stats (uptime, SW version, RX chans, GPS)
• GPS Status (acquisition, tracking, fixes)
• Waterfall Stats (frame rate, audio kbps, queue length)
• BeagleBone Utilization Stats, CPU Load
• Network Stats (audio bw, waterfall bw)
