tiny SCR PRESELECTOR
1-
Band selection.
By default Band A. Click over any button to change band.
2-
Tuning Decrement
One step frequency decrement. One step increment of capacity.
3-
Status Bar
4-
Tune Dial
Displays the tuning value in picoFarads.
Notice due to the response of series tuned circuits, the attenuation of the pass band filter
increases with less capacity. A good practice is to avoid smaller values .
5-
Tuning knob
Performs tuning moving left or right. Also by pressing left or right arrows on the keyboard or
turning mouse wheel. Adjust to maximum signal or background noise.
The tune reference is expressed in picofarads with values between 10pF and 255pF.
Sliding right or left increases or decreases the band-pass frequency.
Notice due to the response of typical series tuned circuits, the attenuation of the pass band filter
increases with less capacity. A good practice is to avoid values smaller than 50 picofarads.
6-
Tuning Increment
One step frequency increment. One step decrement of capacity.
7-
Memories
There are up to five memories per band (25 in total).
Clear-Store and Recall functions for each memory position
.
Store function lets write a text label.
The Software
The software program on the PC runs under Windows 2K, XP, Vista32 and Windows 7 OS.
Windows 2K users need to update Framework from Windows Update site.
The user through the Graphic User Interface commands the tiny SCR Preselector.
The program can work at the same time with any SDR software running on the PC, without interference
allowing to the user to control both simultaneously.
