G8JCFSDR
SDR Console with Frequency Control Function
+
This universally usable SDR software supports (from build 186) also frequency tuning of the DRB 30.
A very comprehensive software eqipped with numerous features and modes written by the British radio amateur PeterCarnegie G8JCF.
This unique software includess a lot of new unique features and abilities. A complete review would require a substantially larger volume.
The best way to get familiar with most features is learning-by-doing. Starting with a basic configuration (default) you might try with different settings & values until you find one that is satisfying.
Modes
Amplitude Modulation: AM, BC (AM Broadcast) , SAM (Synchronous Demodulator)
SSB: LSB, USB
Frequency Modulation: FM
DRM: Therefore the DREAM software has to be installed additionally . When selecting DRM DREAM starts automatically and runs in the background.
Frequency Control
Several tuning mechanisms are possible:
- Mouse Scroll Wheel- Keyboard <- and -> arrow key
- Optional encoder
Therefore first move the mouse pointer over the digit you want to tune.
Besides this it is also possible to select & edit preset frequencies. Also broadcast & amateur radio bands & bandplans are included.
Filtering
400Hz - 5KHz plus dynamic & special music filters
Notch Filtering
Automatic & mirror frequency suppression
Filter Settings
Manual configuration & automatic tracking
AGC
Fast, normal & slow
Noise Reduction
0 - 40% slider controls
Audio Recorder
The audio recorder makes it possible to record the demodulated audio into WAV files
Scope
Frequency spectrum (Freq) & oscilloscope function (time & phase)
Below you will find a few screenshots concerning configuration (Config) of the DRB 30:
Select the SDRModel NTI DRB 30. According settings are loaded automatically >>> Default
IF offset is 44 998 000 (Hz) = 44.980.000MHz. With this setting the tuned signal is displayed in the middle of the spectrum display with 12KHz sweep range.
As an alternative it is also possible to select the real IF of 45 000 000 (Hz) = 45.000.000MHz with a 2KHz offset in spectral display.
Here we see the default values of the printer port adress.
Standard port adress is LPT1 (according HEX &H378). An alternative would be LPT2 (according HEX &H278).
Beginning with build 191 frequency tuning is also supported via the optional USB adaptor DRB USB. Therefore select accordingly NTI USB:
