RF Spectrum Mod

RF Spectrum Mod adds a functional approximation of the RF Spectrum and utilities to Kitten Space Agency.

Major features include:

• Tunable Receiver (14mhz to 10ghz)
• Real Free Space Path Loss calculations
• Broadcast Radio Stations (find them between 88mhz to 108mhz)
• City-Based Morse Code Identifiers (around 145.700 mhz)
• Vessel Radar and Tracking
• Jovian Radio Emissions (18 to 22mhz)
• Deep Space Radio Astronomy Objects (limited as of 0.1.1) (1420mhz)

REQUIRED MODLOADER: StarMap 0.3.5

KSA VER: v2025.12.31.3103 (should be version agnostic)

Reciever Panel

RCVR PANEL * The Receiver panel is your main window for controlling the radio and mod features. From top to bottom: * Mode will set the receiver mode. Broadcast stations are in FM mode only. Beacons can be heard in CW or USB mode. * There are two VFOs, A and B. Pressing MEM will set the current frequency to the active VFO (amber) * The _ next to the frequency readout will minimize the window. If you lose the window F9 will restore it. * The S-Meter gives you an indication of signal strength. * Below that is your direct frequency input. Use numbers only for direct input. * You can tune the frequency with the tuning Knob and also set the volume. SQL is not implemented yet. * STEP will change the tuning step (improvements coming) * Antenna mode is not implemented but will be when I graduate to parts. * Press MUTE to enable audio (it will turn green). Red Mute means audio is muted. * Decoder is not implemented (will be used for data mode when finished)

TOOLS: * SCAN: Moves through the scan range to find signals. (not implemented) * PEAK: Finds the strongest signal (automatic now, not implemented) * RADAR: Opens the radar panel * CEL OFF: Enabled the celestial grid (not implemented) * RA: Expands the Radio Astronomy pointer and tracking (not fully implemented) * DATA: Opens the DATA window (not implemented)

DISPLAY: * SCOPE: Enables/Disables the Waterfall or Bandscope * SPEC: Enables/Disables the Spectrum Scope * SPAN: Controls the passband visibility of the two scopes. (100khz to 50mhz)

WATERFALL & SPECTRUM SCOPE: * Visual representation of band activity for the selected span

Radar Panel

RADAR PANEL

The radar panel will display transmitters and radar 'echoes'

A transmitter is an emitter of RF frequency with some audio or data signal. This is often another vessel or ground transmitter, marked as TX: {Identity}

An echo is a simulated radar return. This is also called a "skin echo" since it simulates a radar pulse echoing off the skin of a vessel. Echos do not currently return identity, adding some mystery to what you are seeing on the scope.

PPI - Plan Position Indicator * The PPI represents the radar antenna as the center of the display. Up is always forward on the display. * The PPI will show a track list, as well as transmitters in range. * Press TRK to move between all radar tracks. * 'A OFF/A ON' will mute/unmute radar sounds * Range keys will change the radar range from 1km to 3000km and is line-of-sight dependant * Show TX / ECHO will hide/show the two classification of radar tracks * SWEEP will hide/show the radar sweep indicator

FWD - Forward Radar Mode The FWD mode will scan a 3D cone area in front of the vessel.

C-S - Cross Section Radar The CS mode will give you a Azimuth/Elevation indication of returns.

See the readme in git for additional details.

Known Issues: * Mute button must be cycled to set changes in Volume (AF) * Squelch SQL: not implemented * RA Targeting: not fully implemented (sky sphere is rotated incorrectly) * Celestial Grid: not implemented * Antenna Mode: not implemented * Scan / Peak: not implemented

Future Plans * Additional radar symbols * Optimization * Bi-Directional Data Modes * Add lightning crash sound * Clean up the code * Complete refactor / rebuilt * Second Pass Bearing & S-Meter Falloff * Method to add BEACON TX to other vessels * Radio and Antenna Parts for vessels * UI panels improvements
