Tuning the PowerSDR receiver.
by Bill KC9XG
Your ANAN-10 is a "knobless" radio. Most functions are performed on a PC with the mouse or via
keyboard commands.
Preliminary receiver setup:
1. On the left side of the PowerSDR window, locate the "AGC Gain" control and set the slider to 90. This
control works similar to an RF gain control, but actually controls the level where the "Automatic Gain Control"
adjusts your receiver gain for best dynamic range. The Panadapter displays a green G and a dotted line
showing the current "AGC Gain" setting. This should be set just above the noise floor displayed on the
panadapter.
2. the "ATT" or Attenuator dropdown box (lower left, below the "AGC Gain" control, should be set to 0db.
Note that some versions of PowerSDR have some attenuator settings that may not work as expected.
Changing frequency:
The mouse can be used to tune signals on the Waterfall or Panadapter. Select an active amateur band by
clicking on one of the band buttons located just below the "S Meter" in the upper right portion of the PowerSDR
window.
1. If you press and hold the left mouse button you can "drag" the frequency of interest into the
panadapter highlighted filter area.
2. If you right click the mouse on the panadapter you can go into "click tune" mode. Left clicking with the
mouse will then QSY the receiver to that frequency. You can right click again to revert from "click tune" mode to
"drag" tuning mode.
3. The "Zoom" slider and the "0.5x, 1x, 2x and 4x" buttons can be used to modify the frequency range
displayed in the panadapter. These controls are located just below the pandapter/waterfall display. The "Pan"
button can be used to move the displayed frequencies within the selected range.
