Basic Controls (left side)...
Mode: Start / Stop processing, Open Setup Screen
Signal: Selects functions to apply to panadapter line
Max... Maximum levels
Avg... Average of number of recent samples set in Setup
Peak... Peak Hold
BPH... Background peak hold
Spot... Centers the strongest signal in the passband
Top... allows TRX-Pan to stay on top of all other windows
Cal... opens screen to adjust levels & range, and to adjust image rejection
Full Screen Toggle... hides the controls so that the panadapter fills the window
Help... Link to F6DEX's TRX-Pan web page.
Zoom: Allows the horizontal scale to be expanded to show narrower frequency spans. Caution: TRX-Pan may need sole control of the sound card if High Res Zoom is selected in Setup.
Waterfall: Controls the percentage of the screen that is filled by the waterfall.
I/Q Rejection... Image rejection adjustments. Tune off of a stable carrier by about 10-20kHz and adjust Phase & Balance sliders for minimum level of the image signal (7.190 in the picture). Clicking above or below the slider bar adjusts in increments of 1 unit. A strong signal is needed to see the maximum null point since image rejection is ~70dB with LP-PAN.
Levels... Adjust the peak of a signal to a known level. This requires a calibrated signal generator such as the Elecraft XG-2. The level can be roughly set to match your S-Meter, though, by tuning in a stable carrier with a level of S9, and setting the peak at the -73dBm red line. Note: TRX-Pan automatically corrects for K3 preamp and attenuator settings so that signal level doesn't change. Noise floor will change to indicate the increased or decreased sensitivity.
Range... Sets the top and bottom limits of the scale, and determines vertical step size. The setting is saved on a band by band basis.
Ref... Sets the vertical centering point of the scale. The setting is saved on a band by band basis.
Note: The Ref and Range also determine the upper and lower levels of the waterfall on a band by band basis.
The settings in the picture are recommended as a starting point for users with a fast PC. FFT bins can be set lower for slower PCs.
Device: Sound card selection. Choose from a list of all available sound cards.
Resolution: 16 or 24 bits (currently locked at 16-bits)
Apodization: Also called "windowing". Affects noise floor and spread of signals.
Sampling Rate: Choices are available for 11025 to 192000 Hz. Note: not all sound cards support all sampling rates.
FFT Bins: Number of samples used in the frequency domain (horizontal). Use 4096 for older PCs, 8192 for newer PCs and 16384 or higher for fast PCs.
Accuracy: Also called RBW (Resolution Bandwidth), indicates the step size between horizontal samples.
Smooth 0Hz spike: Minimizes the effect of poor DC offset performance in inexpensive sound cards. Can also be used to minimize small amounts of hum.
MAX/AVG Samples: Sets the number of samples that are included when the AVG or MAX buttons are pressed in the Control section.
Priority: Real Time: Allows the program to take priority over all other PC processes. Use with care... can cause crashes of other programs.
Reverse IQ: Reverses sidebands. Same as swapping cables from LP-PAN.
Flip I/Q on 6m: Reverses sidebands on 6m to match the K3.
QSY Detect: Switches off AVG or MAX during tuning to make signals easier to see as they move.
High Res. Zoom: Readjusts sampling rate at higher zoom levels to maintain high RBW with narrower spans. Recommended. Caution: TRX-Pan may need sole control of the sound card if this is checked.
Color: Allows adjustment of the colors of background, lines, traces, text, etc.
Fill: Fills in below the panadapter trace to make it easier to see.
Subdivision Lines: Adds 5 lines between each major line to allow you to determine trace positions more accurately.
Design: 1 or 2... S-Meter, passband lines and other graphic elements are slightly different between these. Design 2 is shown.
CAT Control: Rig connection choices... TRX-Manager, TRX-Manager + K3 (IF offset), LP-Bridge, N4PY. The latter three choices allow tracking IF offset of K3 or other rig in addition to rig control. Additional boxes for mode offsets appear when the rig or program does not support IF offsets. LP-Bridge currently only supports K3 rig control, but we will be adding choices for Kenwood, Yaesu (FT-950/2000/5000) and K2. For rigs other than K3, you can use TRX-Manager or N4PY, which also provide a connection for a separate logger or CW Skimmer.
SDR: Choices are LP-PAN and Fixed LO (SoftRock connected to antenna).
Global Offset: Used to synchronize the rig and LP-PAN local oscillators. The nominal value is -6.000kHz for K3.
Lower Left Buttons: F6DEX Help page, N8LP Help page (this page), TRX-Manager main web page
MouseWheel Enabled: Allows you to fine tune with the mousewheel immediately after clicking on a signal. You can enter separate tuning rates based on mode. These steps also determine the rounding values when clicking.
