Quick Start

Watch Live Spots

bash

# Get latest DX spots
python3 dx-monitor.py watch

# Specific cluster node
python3 dx-monitor.py watch --cluster ea7jxh

# Use your callsign
python3 dx-monitor.py watch --callsign KN4XYZ

# Only show NEW spots (filters duplicates)
python3 dx-monitor.py watch --new-only

DX Cluster Nodes

Available clusters:

• ea7jxh - dx.ea7jxh.eu:7373 (Europe)
• om0rx - cluster.om0rx.com:7300 (Europe)
• oh2aq - oh2aq.kolumbus.fi:7373 (Finland)
• ab5k - ab5k.net:7373 (USA)
• w6rk - telnet.w6rk.com:7373 (USA West Coast)

Automated Monitoring

Using OpenClaw Cron (Recommended)

Use the OpenClaw cron tool to set up monitoring:

bash

# Create a cron job for DX alerts (every 5 minutes)
cron add --name "DX Monitor" --schedule "*/5 * * * *" --payload 'systemEvent:Check DX cluster for rare spots' --sessionTarget main

Manual Cron (Alternative)

If using system cron, run as a non-privileged user:

bash

# Add to crontab (as your user, not root)
crontab -e

# Add these lines:
*/5 * * * * cd ~/clawd && python3 skills/ham-radio-dx/dx-monitor.py watch --new-only --callsign YOUR_CALL >> ~/dx-alerts.log 2>&1

# Daily digest at 9am
0 9 * * * cd ~/clawd && python3 skills/ham-radio-dx/dx-monitor.py digest >> ~/dx-digest-$(date +\%Y-\%m-\%d).txt 2>&1

Note: State is saved to ~/dx-monitor-state.json (in your home directory, not /tmp).

Example Prompts for Clawdbot

• "Check the DX cluster for new spots"
• "What's active on 20 meters?"
• "Show me today's DX digest"
• "Any rare DX on the air?"
• "Monitor for VP8 or ZL prefixes"

Tips

1. Use Your Callsign - Some clusters require valid callsigns
2. Check Multiple Clusters - Coverage varies by region
3. Filter by Band - Focus on bands you can work
4. Track Rare Prefixes - Set up alerts for most-wanted
5. Morning Check - Best DX often in early morning
