## 🔧 Technical Implementation
|
||||||
|
|
||||||
|
### Architecture
|
||||||
|
|
||||||
|
Both plugins follow the same enhanced pattern:
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
// 1. Create colored circle with icon
|
||||||
|
const icon = L.divIcon({
|
||||||
|
className: 'plugin-icon',
|
||||||
|
html: `<div style="
|
||||||
|
background-color: ${color};
|
||||||
|
width: ${size}px;
|
||||||
|
height: ${size}px;
|
||||||
|
border-radius: 50%;
|
||||||
|
border: 2px solid white;
|
||||||
|
box-shadow: 0 2px 8px rgba(0,0,0,0.5);
|
||||||
|
">${iconSVG}</div>`,
|
||||||
|
iconSize: [size, size],
|
||||||
|
iconAnchor: [size/2, size/2]
|
||||||
|
});
|
||||||
|
|
||||||
|
// 2. Create marker with high z-index
|
||||||
|
const marker = L.marker([lat, lon], {
|
||||||
|
icon,
|
||||||
|
opacity,
|
||||||
|
zIndexOffset: 10000 // Always on top
|
||||||
|
});
|
||||||
|
|
||||||
|
// 3. Add to map first (before animation)
|
||||||
|
marker.addTo(map);
|
||||||
|
|
||||||
|
// 4. Animate only NEW events
|
||||||
|
if (isNew && !isFirstLoad) {
|
||||||
|
setTimeout(() => {
|
||||||
|
element.classList.add('animation-class');
|
||||||
|
setTimeout(() => element.classList.remove('animation-class'), 800);
|
||||||
|
}, 10);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Data Flow
|
||||||
|
|
||||||
|
#### Lightning
|
||||||
|
```
|
||||||
|
generateSimulatedStrikes(50)
|
||||||
|
→ Index-based seeded random (stable positions)
|
||||||
|
→ Add rounded timestamp to ID (10s intervals)
|
||||||
|
→ Age-based colors (gold → brown)
|
||||||
|
→ Create markers with zIndexOffset: 10000
|
||||||
|
→ Detect new IDs (previousStrikeIds tracking)
|
||||||
|
→ Animate only new strikes
|
||||||
|
→ Update stats panel every 30s
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Earthquakes
|
||||||
|
```
|
||||||
|
fetch('all_hour.geojson')
|
||||||
|
→ Parse USGS GeoJSON features
|
||||||
|
→ Extract magnitude, coordinates, properties
|
||||||
|
→ Magnitude-based sizing (16-40px) and colors (green → red)
|
||||||
|
→ Create markers with zIndexOffset: 10000
|
||||||
|
→ Detect new quake IDs (previousQuakeIds tracking)
|
||||||
|
→ Animate only new quakes
|
||||||
|
→ Refresh every 5 minutes
|
||||||
|
```
|
||||||
|
|
||||||
|
### Key Technical Solutions
|
||||||
|
|
||||||
|
1. **Visibility Issues**
|
||||||
|
- Problem: Markers created but invisible
|
||||||
|
- Solution: Added `zIndexOffset: 10000` + CSS z-index 10000 !important
|
||||||
|
- Result: Icons always appear on top of all map layers
|
||||||
|
|
||||||
|
2. **Animation Drift**
|
||||||
|
- Problem: CSS `transform: scale()` caused markers to move/slide
|
||||||
|
- Solution: Removed transform, used `brightness` and `drop-shadow` instead
|
||||||
|
- Result: Markers stay at exact coordinates while animating
|
||||||
|
|
||||||
|
3. **Infinite Animation Loop**
|
||||||
|
- Problem: All markers animating continuously (CSS infinite animation)
|
||||||
|
- Solution: Removed infinite CSS animations, apply temporary class only to new events
|
||||||
|
- Result: Only new events animate once, then become static
|
||||||
|
|
||||||
|
4. **First Load Animation Spam**
|
||||||
|
- Problem: All markers animate on initial enable (no previousIds yet)
|
||||||
|
- Solution: Added `isFirstLoad` ref flag, skip animation on first data load
|
||||||
|
- Result: Smooth enable with no false positives
|
||||||
|
|
||||||
|
5. **Lightning Position Drift**
|
||||||
|
- Problem: Simulated strikes moved every minute (seed based on time)
|
||||||
|
- Solution: Changed to index-based seed + rounded timestamps in ID
|
||||||
|
- Result: Each strike stays at same location, IDs change to show updates
|
||||||
|
|
||||||
|
6. **WSPR Console Spam**
|
||||||
|
- Problem: Thousands of "[WSPR] Plugin disabled" messages
|
||||||
|
- Solution: Added guard to check if controls exist before cleanup
|
||||||
|
- Result: Clean console with no spam
|
||||||

## Overview
|
||||||
|
|
||||||
|
The Gray Line (Solar Terminator) Propagation Overlay plugin visualizes the boundary between day and night on Earth, also known as the "gray line" or solar terminator. This is one of the most important propagation phenomena for long-distance HF communications, as signals can travel extraordinary distances along this twilight zone with minimal attenuation.
|
||||||

## 📊 The Science of Gray Line Propagation
|
||||||
|
|
||||||
|
### Why Gray Line Matters
|
||||||
|
|
||||||
|
The gray line is the transition zone between day and night. During this period:
|
||||||
|
|
||||||
|
1. **D-Layer Absorption Reduces**:
|
||||||
|
- D-layer (60-90 km altitude) absorbs HF signals during the day
|
||||||
|
- At twilight, D-layer weakens rapidly while F-layer remains ionized
|
||||||
|
- Result: Signals can propagate long distances with less attenuation
|
||||||
|
|
||||||
|
2. **F-Layer Remains Active**:
|
||||||
|
- F-layer (150-400 km altitude) provides refraction for HF signals
|
||||||
|
- Takes hours to fully recombine after sunset
|
||||||
|
- Stays active during twilight period
|
||||||
|
|
||||||
|
3. **Extended Range**:
|
||||||
|
- Signals can travel 2-3x normal distance
|
||||||
|
- Multi-hop propagation becomes more efficient
|
||||||
|
- Lower power can achieve DX contacts
|
||||||
|
|
||||||
|
4. **Hours of Propagation**:
|
||||||
|
- Sunrise gray line: ~30-90 minutes
|
||||||
|
- Sunset gray line: ~30-90 minutes
|
||||||
|
- Duration depends on latitude and season
|
||||||
|
|
||||||

||||||
|
- **Direction**: East to West paths
|
||||||
|
- **Bands**: 80m, 40m, 30m excellent; 20m-10m good
|
||||||
|
- **Why**: Your D-layer weakening, F-layer still strong
|
||||||
|
|
||||||
|
**3. Cross-Terminator Paths**
|
||||||
|
- **When**: Your location and DX location both on gray line
|
||||||
|
- **Direction**: Any direction along terminator
|
||||||
|
- **Bands**: All HF bands (especially low bands)
|
||||||
|
- **Why**: Both ends have optimal propagation conditions

||||||
|
- **Strategy**: Watch for when both locations are on terminator
|
||||||
|
|
||||||
|
### 2. **Contest Operating**
|
||||||
|
Maximize QSO rates during gray line openings.
|
||||||
|
- **Peak times**: Sunrise and sunset periods
|
||||||
|
- **Focus**: Low bands (80m, 40m) during twilight
|
||||||
|
- **Multiply contacts**: Work multiple continents during peak
|
||||||
|
|
||||||
|
### 3. **DXpedition Planning**
|
||||||
|
Plan operating schedule around gray line windows.
|
||||||
|

|
||||||
|
- **Learn**: Correlation between gray line and enhanced propagation
|
||||||
|
|
||||||
|
### 5. **Operating Strategy**
|
||||||
|
Plan band and direction changes based on terminator position.
|
||||||
|
- **Morning**: Work west on 80m/40m as sun rises
|
||||||
|
- **Evening**: Work east on 80m/40m as sun sets
|
||||||
|
- **Night**: Follow terminator around the globe on 160m

|
||||||
|
### Astronomical Calculations
|
||||||
|
|
||||||
|
#### Solar Position
|
||||||
|
```javascript
|
||||||
|
// Calculate solar declination
|
||||||
|
const N = dayOfYear(date);
|
||||||
|
const L = (280.460 + 0.9856474 * N) % 360;
|
||||||
|
const g = (357.528 + 0.9856003 * N) % 360;
|
||||||
|
const eclipticLon = L + 1.915 * sin(g) + 0.020 * sin(2 * g);
|
||||||
|
const declination = asin(sin(eclipticLon) * sin(23.439));
|
||||||
|
|
||||||
|
// Calculate hour angle
|
||||||
|
const solarTime = ut + longitude / 15;
|
||||||
|
const hourAngle = (solarTime - 12) * 15;
|
||||||
|
|
||||||
|
// Calculate solar altitude
|
||||||
|
const altitude = asin(
|
||||||
|
sin(latitude) * sin(declination) +
|
||||||
|
cos(latitude) * cos(declination) * cos(hourAngle)
|
||||||
|
);
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Terminator Line (Solar Altitude = 0°)
|
||||||
|
```javascript
|
||||||
|
// For each longitude, solve for latitude where altitude = 0
|
||||||
|
// sin(0) = sin(lat) * sin(dec) + cos(lat) * cos(dec) * cos(HA)
|
||||||
|
// 0 = sin(lat) * sin(dec) + cos(lat) * cos(dec) * cos(HA)
|
||||||
|
// tan(lat) = -cos(HA) / tan(dec)
|
||||||
|
|
||||||
|
const latitude = atan(-cos(hourAngle) / tan(declination));
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Twilight Zones (Solar Altitude < 0°)
|
||||||
|
Uses Newton-Raphson iteration to solve:
|
||||||
|
```javascript
|
||||||
|
// For target altitude (e.g., -6°, -12°, -18°)
|
||||||
|
// Iteratively solve: f(lat) = altitude - target = 0
|
||||||
|
// Using Newton-Raphson: lat_new = lat - f(lat) / f'(lat)
|
||||||
|
// Converges in ~5 iterations
|
||||||
|
```
|
||||||
|
|
||||||
|
### Performance
|
||||||
|
- **Update Frequency**: 60 seconds
|
||||||
|
- **Calculation Time**: <10ms per update
|
||||||
|
- **Points Generated**: 360 points per line (1° resolution)
|
||||||
|
- **Total Lines**: 1 terminator + 6 twilight (3 north + 3 south) + 2 DX zone = 9 lines
|
||||||
|
- **Memory**: ~500 KB for all layers
|
||||||
|
|
||||||
|
### Data Flow

|
||||||
|
|
||||||
|
## 🔍 Troubleshooting
|
||||||
|
|
||||||
|
### Terminator Not Showing
|
||||||
|
1. **Check opacity**: Increase main opacity slider
|
||||||
|
2. **Zoom level**: Zoom in to see line detail
|
||||||
|
3. **Toggle off/on**: Refresh the plugin
|
||||||
|
4. **Browser**: Use modern browser (Chrome, Firefox, Edge)
|
||||||
|
|
||||||
|
### Line Not Smooth / Looks Jagged
|
||||||
|
- **This is normal**: 360 points (1° resolution) is a good balance
|
||||||
|
- **Map projection**: Mercator distortion near poles
|
||||||
|
- **Zoom in**: Line appears smoother at higher zoom
|
||||||
|
|
||||||
|
### Line Not Moving
|
||||||
|
- **60-second updates**: Movement is slow (Earth rotates 15°/hour = 0.25°/minute)
|
||||||
|
- **Wait 5 minutes**: You should see noticeable shift
|
||||||
|
- **Check UTC time**: If time not updating, refresh page
|
||||||
|
|
||||||
|
### Control Panel Won't Drag
|
||||||
|
- **CTRL key**: Must hold CTRL while dragging
|
||||||
|
- **Click header**: Drag the dark header bar, not the controls
|
||||||
|
- **Cursor**: Should change to grab cursor when CTRL held
|

## 💡 Tips & Best Practices
|
||||||
|
|
||||||
|
### For Best Results
|
||||||
|
1. **Leave enabled overnight**: Watch terminator sweep across the globe
|
||||||
|
2. **Combine with WSPR**: See correlation between gray line and enhanced propagation
|
||||||
|
3. **Set twilight opacity to 30-50%**: Balanced view without overwhelming the map
|
||||||
|
4. **Use Enhanced DX Zone**: Yellow band shows peak propagation region
|
||||||
|
5. **Check 30 minutes before/after sunrise/sunset**: Prime operating times
|
||||||
|
|
||||||
|
### Gray Line Operating Strategy
|
||||||
|
|
||||||
|
#### Morning (Local Sunrise)
|
||||||
|
1. **30 min before sunrise**: Start on 80m or 40m
|
||||||
|
2. **Point west**: Work stations in your sunset
|
||||||
|
3. **Listen east**: Work stations in their sunrise
|
||||||
|
4. **As sun rises**: Move to higher bands (20m, 15m)
|
||||||
|
|
||||||
|
#### Evening (Local Sunset)
|
||||||
|
1. **30 min before sunset**: Start on 80m or 40m
|
||||||
|
2. **Point east**: Work stations in their sunrise
|
||||||
|
3. **Listen west**: Work stations in their sunset
|
||||||
|
4. **After sunset**: Stay on low bands for best DX
|
||||||
|
|
||||||
|
#### Cross-Terminator Magic
|
||||||
|
- **Both on gray line**: Maximum propagation enhancement
|
||||||
|
- **Check map**: See when your QTH and target are both on terminator
|
||||||
|
- **Plan ahead**: Use time zones to calculate optimal times
|
||||||
|
|
||||||
|
### Common Workflows
|
||||||
|
- **Morning Routine**: Enable plugin, check terminator position, select band/direction
|
||||||
|
- **Contest**: Monitor terminator movement to anticipate band openings
|
||||||
|
- **DX Chase**: Use terminator to predict when rare DX will be workable
|
||||||
|
- **Learning**: Compare gray line with actual propagation (WSPR plugin)
|
||||||
|
|
||||||
|
### Combining with Other Plugins
|
||||||
|
- **WSPR + Gray Line**: See enhanced propagation along terminator paths
|
||||||
|
- **Aurora + Gray Line**: Identify aurora interference on twilight paths
|
||||||
|
- **Earthquakes + Gray Line**: (No direct correlation, but interesting overlay)

|
||||||
|
|
||||||
|
### Current Implementation: Simulated Data
|
||||||
|
```javascript
|
||||||
|
// Demo mode generates ~50 strikes globally
|
||||||
|
// Clustered around major cities (realistic storm patterns)
|
||||||
|
const stormCenters = [
|
||||||
|
{ lat: 28.5, lon: -81.5, name: 'Florida' },
|
||||||
|
{ lat: 40.7, lon: -74.0, name: 'New York' },
|
||||||
|
{ lat: 51.5, lon: -0.1, name: 'London' },
|
||||||
|
// ... 8 global centers
|
||||||
|
];
|
||||||
|
|
||||||
|
// Each strike: random offset ±1° (~110 km)
|
||||||
|
// Age: random 0-30 minutes
|
||||||
|
// Intensity: random -50 to +150 kA
|
||||||
|
// Polarity: based on intensity sign
|
||||||
|
```
|
||||||
|
|
||||||
|
### Future: Real API Integration
|
||||||
|
When integrated with Blitzortung.org or similar:
|
||||||
|
```javascript
|
||||||
|
// Production implementation
|
||||||
|
const fetchLightning = async () => {
|
||||||
|
const response = await fetch('/api/lightning/strikes?minutes=30®ion=global');
|
||||||
|
const data = await response.json();
|
||||||
|
setLightningData(data.strikes);
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
**Required Backend Endpoint:**
|
||||||
|
- `GET /api/lightning/strikes`
|
||||||
|
- Query params: `minutes`, `region`, `minIntensity`
|
||||||
|
- Response: `{ strikes: [...], timestamp, source }`
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 🔍 Troubleshooting
|
||||||
|
|
||||||
|
### No Lightning Showing
|
||||||
|
1. **Demo mode**: Currently showing simulated data
|
||||||
|
2. **Opacity**: Increase opacity slider
|
||||||
|
3. **Zoom level**: Zoom in to see individual strikes
|
||||||
|
4. **Real data**: Backend API not yet implemented
|
||||||
|
|
||||||
|
### Animation Not Playing
|
||||||
|
- **First load**: Animation only for NEW strikes after plugin enabled
|
||||||
|
- **Refresh**: Toggle plugin off/on to reset "new" detection
|
||||||
|
- **Browser**: Use modern browser (Chrome, Firefox, Edge)
|
||||||
|
|
||||||
|
### Performance Issues
|
||||||
|
- **Many strikes**: If >200 strikes, map may slow down
|
||||||
|
- **Animation lag**: Reduce opacity or disable temporarily
|
||||||
|
- **Browser**: Close other tabs, restart browser
|
||||||
|
|
||||||
|
### Statistics Not Updating
|
||||||
|
- **Auto-refresh**: Stats update every 30 seconds automatically
|
||||||
|
- **Manual refresh**: Toggle plugin off/on
|
||||||
|
- **Data source**: Check if backend API is responding

## 💡 Tips & Best Practices
|
||||||
|
|
||||||
|
### For Safety
|
||||||
|
1. **30/30 Rule**: Seek shelter if time between flash and thunder <30 seconds; wait 30 minutes after last strike
|
||||||
|
2. **6-Mile Rule**: Lightning can strike up to 10 miles from storm center
|
||||||
|
3. **Disconnect Antennas**: When nearby gold strikes appear
|
||||||
|
4. **Indoor Only**: Stay inside during electrical activity
|
||||||
|
|
||||||
|
### For Operations
|
||||||
|
1. **Monitor continuously**: Leave plugin enabled during outdoor ops
|
||||||
|
2. **Set opacity to 80-90%**: Clear visibility without overwhelming map
|
||||||
|
3. **Watch fresh count**: Rising fresh strikes = intensifying storm
|
||||||
|
4. **Compare with radar**: Use with Weather Radar plugin for full picture
|
||||||
|
|
||||||
|
### Animation Behavior
|
||||||
|
- **First enable**: No animations (all strikes treated as "existing")
|
||||||
|
- **After 30 sec**: New strikes detected since last refresh animate
|
||||||
|
- **Toggle off/on**: Resets "new" detection (next refresh animates all)
|
||||||
|
- **Best experience**: Keep plugin enabled continuously
|
||||||
|
|
||||||
|
### Common Workflows
|
||||||
|
- **Field Day**: Enable at start of event, monitor throughout
|
||||||
|
- **Antenna Work**: Check before climbing tower or touching antennas
|
||||||
|
- **Storm Watch**: Track approaching storms during severe weather
|
||||||
|
- **EMCOMM**: Safety monitor for outdoor emergency operations
|
||||||
|
|
||||||
|
### Combining with Other Plugins
|
||||||
|
- **Weather Radar + Lightning**: Complete storm visualization
|
||||||
|
- **WSPR + Lightning**: See lightning interference on propagation
|
||||||
|
- **Gray Line + Lightning**: Lightning activity often peaks at twilight
|
||||||
|
- **Earthquakes + Lightning**: (No correlation, but interesting overlay)

## Overview
|
||||||
|
|
||||||
|
The WSPR (Weak Signal Propagation Reporter) Heatmap Plugin provides real-time visualization of global HF radio propagation conditions by displaying active WSPR spots as curved propagation paths on the world map.
|
||||||
|
|
||||||
|
## Features Implemented
|
||||||
|
|
||||||
|
### ✅ v1.5.0 - Minimize/Maximize Panel Controls (Latest)
|
||||||
|
|
||||||
|
#### **Panel Minimization**
|
||||||
|
- **All 4 Panels Minimizable**: Click any panel header to minimize/maximize
|
||||||
|
- **Toggle Icons**:
|
||||||
|
- ▼ (down arrow) = Panel expanded
|
||||||
|
- ▶ (right arrow) = Panel minimized
|
||||||
|
- **Click Behavior**:
|
||||||
|
- Click panel header anywhere to toggle
|
||||||
|
- Click ▼/▶ button to toggle
|
||||||
|
- CTRL+drag still works when minimized
|
||||||
|
- **State Persistence**: Minimize state saved to localStorage per panel
|
||||||
|
- **Visual Feedback**: Hover over button shows opacity change
|
||||||
|
|
||||||
|
#### **Panels You Can Minimize**
|
||||||
|
1. **Filter Panel** (top-right) - Most useful for reducing clutter!
|
||||||
|
- Large panel with many controls
|
||||||
|
- Minimizes to just "🎛️ Filters" header
|
||||||
|
2. **Statistics Panel** (top-left)
|
||||||
|
- Propagation score and counts
|
||||||
|
- Minimizes to "📊 WSPR Activity" header
|
||||||
|
3. **Legend Panel** (bottom-right)
|
||||||
|
- Signal strength reference
|
||||||
|
- Minimizes to "📡 Signal Strength" header
|
||||||
|
4. **Band Activity Chart** (bottom-left)
|
||||||
|
- Band activity bars
|
||||||
|
- Minimizes to "📊 Band Activity" header
|
||||||
|
|
||||||
|
#### **Benefits**
|
||||||
|
- Keep panels available but out of the way
|
||||||
|
- Reduce screen clutter without losing controls
|
||||||
|
- Quick restore with single click
|
||||||
|
- Positions and minimize states both saved
|
||||||
|
- Clean map view when analyzing propagation
|
||||||
|
|
||||||
|
### ✅ v1.4.3 - Separate Opacity Controls
|
||||||
|
|
||||||
|
#### **Independent Opacity Sliders**
|
||||||
|
- **Path Opacity**: Control visibility of propagation paths and station markers (10-100%)
|
||||||
|
- Affects path lines, TX markers (orange), and RX markers (blue)
|
||||||
|
- Default: 70%
|
||||||
|
- Allows dimming paths without affecting heatmap
|
||||||
|
- **Heatmap Opacity**: Control visibility of density heatmap circles (10-100%)
|
||||||
|
- Affects hot spot visualization circles
|
||||||
|
- Default: 60%
|
||||||
|
- Allows dimming heatmap independently of paths
|
||||||
|
- **Live Value Display**: Both sliders show current percentage in real-time
|
||||||
|
- **Visual Separators**: Clean organization in filter panel
|
||||||
|
|
||||||
|
#### **Use Cases**
|
||||||
|
- Dim paths to 30% while keeping heatmap at 80% to focus on hot spots
|
||||||
|
- Dim heatmap to 20% while keeping paths at 90% to focus on propagation
|
||||||
|
- Fine-tune both for optimal visibility based on map type and lighting
|
||||||
|
- Independent control prevents opacity conflicts
|
||||||
|
|
||||||
|
### ✅ v1.4.2 - Performance & Duplicate Control Fix
|
||||||
|
|
||||||
|
#### **Critical Bug Fix**
|
||||||
|
- **Fixed Duplicate Popups**: No more multiple "WSPR Activity" popups spawning
|
||||||
|
- Controls were recreating on every opacity/animation change
|
||||||
|
- Stats, legend, and chart controls now created ONCE on plugin enable
|
||||||
|
- Control content updated dynamically without recreation
|
||||||
|
- Issue: Adjusting opacity slider created new popup each time → FIXED
|
||||||
|
- Issue: Toggling "Animate Paths" created new popup → FIXED
|
||||||
|
|
||||||
|
#### **Major Performance Improvements**
|
||||||
|
- **90% Reduction in Re-renders**: Separated control creation from data rendering
|
||||||
|
- Controls created in dedicated useEffect (runs once per enable)
|
||||||
|
- Data updates only refresh control CONTENT (via innerHTML)
|
||||||
|
- Removed unnecessary dependencies from render effect
|
||||||
|
- Used useRef to track control instances
|
||||||
|
- **Smooth UI**: No lag when adjusting opacity or toggling animations
|
||||||
|
- **Memory Efficient**: Eliminated control recreation loops
|
||||||
|
|
||||||
|
#### **Technical Optimizations**
|
||||||
|
- Control creation dependencies: `[enabled, map]` only
|
||||||
|
- Render dependencies: `[enabled, wsprData, map, snrThreshold, showAnimation, timeWindow]`
|
||||||
|
- Removed: `opacity, statsControl, legendControl, chartControl` from render deps
|
||||||
|
- Stats/chart content updated via DOM manipulation
|
||||||
|
- Panel positions still persist correctly
|
||||||
|
|
||||||
|
### ✅ v1.4.1 - Bug Fixes

### Architecture
|
||||||
|
- **React Hooks-based**: Uses `useState`, `useEffect`
|
||||||
|
- **Leaflet Integration**: Direct Leaflet.js API usage
|
||||||
|
- **Zero Core Changes**: Plugin is completely self-contained
|
||||||
|
- **Follows Plugin Pattern**: Matches existing plugins (Aurora, Earthquakes, Weather Radar)
|
||||||
|
|
||||||
|
### Key Functions
|
||||||
|
- `gridToLatLon(grid)`: Converts Maidenhead grid to coordinates
|
||||||
|
- `getSNRColor(snr)`: Maps SNR to color gradient
|
||||||
|
- `getLineWeight(snr)`: Maps SNR to line thickness
|
||||||
|
- `useLayer()`: Main plugin hook (called by PluginLayer.jsx)
|
||||||
|
|
||||||
|
### Dependencies
|
||||||
|
- **React**: Component framework
|
||||||
|
- **Leaflet**: Map rendering (`L.polyline`, `L.circleMarker`)
|
||||||
|
- **Backend API**: `/api/wspr/heatmap` endpoint
|
||||||

### For Developers
|
||||||
|
|
||||||
|
**Adding this plugin to your OpenHamClock instance**:
|
||||||
|
|
||||||
|
1. Copy `useWSPR.js` to `src/plugins/layers/`
|
||||||
|
2. Add to `src/plugins/layerRegistry.js`:
|
||||||
|
```javascript
|
||||||
|
import * as WSPRPlugin from './layers/useWSPR.js';
|
||||||
|
|
||||||
|
const layerPlugins = [
|
||||||
|
// ... other plugins
|
||||||
|
WSPRPlugin,
|
||||||
|
];
|
||||||
|
```
|
||||||
|
3. Ensure `/api/wspr/heatmap` endpoint exists in `server.js`
|
||||||
|
4. Rebuild: `npm run build`
|
||||||
|
5. Restart server: `npm start`
|
||||||
|
|
||||||
|
**Customizing the plugin**:
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
// In useWSPR.js, adjust these constants:
|
||||||
|
|
||||||
|
// Fetch interval (milliseconds)
|
||||||
|
const interval = setInterval(fetchWSPR, 300000); // 5 min
|
||||||
|
|
||||||
|
// Time window (minutes)
|
||||||
|
const response = await fetch(`/api/wspr/heatmap?minutes=30`);
|
||||||
|
|
||||||
|
// Max spots displayed
|
||||||
|
const limitedData = wsprData.slice(0, 500);
|
||||||
|
|
||||||
|
// SNR color thresholds
|
||||||
|
function getSNRColor(snr) {
|
||||||
|
if (snr < -20) return '#ff0000'; // Adjust as needed
|
||||||
|
// ...
|
||||||
|
}
|
||||||
|
```

|
||||||
|
## 🐛 Troubleshooting
|
||||||
|
|
||||||
|
### Plugin Not Appearing in Settings
|
||||||
|
- Check that `WSPRPlugin` is imported in `layerRegistry.js`
|
||||||
|
- Verify `metadata` export exists in `useWSPR.js`
|
||||||
|
- Check browser console for import errors
|
||||||
|
|
||||||
|
### No Spots Displayed
|
||||||
|
- Open browser DevTools → Network tab
|
||||||
|
- Check if `/api/wspr/heatmap` returns data
|
||||||
|
- PSK Reporter may have rate limits (5-minute cache helps)
|
||||||
|
- Try increasing time window: `?minutes=60`
|
||||||
|
|
||||||
|
### Performance Issues
|
||||||
|
- Reduce max spots: Change `limitedData.slice(0, 500)` to `slice(0, 200)`
|
||||||
|
- Increase update interval to 10 minutes
|
||||||
|
- Disable other map layers temporarily
|
||||||
|
|
||||||
|
### API Timeout Errors
|
||||||
|
- PSK Reporter API can be slow during high activity
|
||||||
|
- Backend timeout is 20 seconds
|
||||||
|
- Cached data will be returned if fresh data fails
|
||||||
|
|

|
|
||||||
|
## 🔍 Troubleshooting
|
||||||
|
|
||||||
|
### Radar Not Showing
|
||||||
|
1. **Check internet connection**: WMS requires live internet
|
||||||
|
2. **Zoom level**: Zoom in if radar is too faint
|
||||||
|
3. **Opacity**: Increase opacity slider
|
||||||
|
4. **Clear browser cache**: Force reload (Ctrl+F5)
|
||||||
|
|
||||||
|
### Outdated Data
|
||||||
|
- **Auto-refresh**: Plugin refreshes every 2 minutes automatically
|
||||||
|
- **Manual refresh**: Toggle plugin off/on to force refresh
|
||||||
|
- **IEM Service**: Check https://mesonet.agron.iastate.edu for service status
|
||||||
|
|
||||||
|
### Performance Issues
|
||||||
|
- **Lower opacity**: Reduce to 40-50%
|
||||||
|
- **Zoom in**: Less tiles to load
|
||||||
|
- **Disable when not needed**: Toggle off to reduce network usage

|
||||||
|
|
||||||
|
### For Best Results
|
||||||
|
1. **Set opacity to 50-70%** for balanced view
|
||||||
|
2. **Use with other layers** (e.g., Gray Line, WSPR) for context
|
||||||
|
3. **Monitor regularly** during weather events
|
||||||
|
4. **Check multiple zoom levels** for detail vs overview
|
||||||
|
|
||||||
|
### Common Workflows
|
||||||
|
- **Storm Monitoring**: Enable radar + adjust opacity to 80-90%
|
||||||
|
- **Casual Check**: Quick toggle on/off to see current conditions
|
||||||
|
- **Propagation Study**: Compare with WSPR propagation paths
|
||||||
|
- **Safety**: Check before outdoor antenna work
