Equipment currently consists of a single SoftRock Ensemble II receiver feeding a Xonar D1 soundcard, using a 2.4 GHz Celeron computer. Linux OS used is now Lubuntu. No preamp is used. The antenna is a vertical wire dipole, suspended approximately 16 meters from the ground.
A few operational tips:
Enlarging the screen waterfall display offers a much easier receiver to tune and monitor. Do this easily by simply increasing the web page size to fill your monitor screen by using the zoom feature offered by your browser. Use the "zoom" buttons on the receiver display located beneath the waterfall settings to achieve a very useful "bandspread" function (you may also place the cursor on the waterfall and use the mouse wheel). To see another frequency segment while zoomed in, click and hold on the waterfall itself and slide the display left or right (works in "zoom" modes only). Using narrow bandwidths is easier when the display is zoomed in. To tune instantly, click on the tick marks area immediately beneath the waterfall to go there. To tune quickly, click and hold immediately below the yellow indicator and slide up or down the band. To "Fine Tune," simply use your mouse wheel anywhere in the frequency dial. Frequency may also be entered directly in the "frequency box." Frequencies may be stored for recall in "Memories."
Please feel welcome to use the Log feature for logging beacons heard; this record may be used for analysis, so please log only beacons and as many as you like. Clicking the mouse wheel to open a log for viewing will avoid closing the receiver.
Operation may be intermittent until a remote site is secured. Weather may also intervene due to frequent thunderstorms in this area. Links below open in another window or tab:
