How do I set up my SuperSID VLF detector software so that data from the Stanford SuperSID device is uploaded to the Stanford SuperSID data server?

To get your SuperSID detector automatically uploading data to the Stanford servers, you only need to enable and verify a few configuration settings. The functionality is already built into the software.


🔧 1. Edit the SuperSID configuration file

Open the file:

C:\supersid_v1_1\Config\supersid.cfg

Use Notepad or similar.


🌐 2. Enable automatic upload

Find this line in the [PARAMETERS] section:

automatic_upload = no

Change it to:

automatic_upload = yes

This is the key switch—without it, nothing gets sent.


📡 3. Check (but don’t change) the server settings

Make sure these are present and correct:

ftp_server = sid-ftp.stanford.edu
ftp_directory = /incoming/SuperSID

These tell SuperSID where to send your files. You normally should not change them unless instructed by Stanford.


⏱️ 4. Understand when uploads happen

  • Data files are written daily at 00:00 UTC
  • At that time, SuperSID checks the upload setting and sends files via FTP automatically

So you won’t see uploads happening continuously—it’s a once-per-day batch.


🌍 5. Ensure internet access

The PC running SuperSID must:

  • Be connected to the internet
  • Allow outbound FTP connections (some firewalls may block this)

🧪 6. Verify it’s working

After a full day:

  1. Check your local folder:C:\supersid_v1_1\Data
  2. Then look for your data on the Stanford SID database:

If your station name is correct in the config, your files should appear there.


⚠️ Common pitfalls

  • Leaving automatic_upload = no
  • Incorrect site_name or monitor_id (affects identification)
  • Firewall blocking FTP
  • No internet at midnight UTC

👍 Practical tip

It’s best to run for a few days first without upload, confirm your signals look good, then enable upload—this is exactly how the SuperSID documentation suggests proceeding.


How to sanity-check your supersid.cfg (especially station list and timing), which often affects whether your uploaded data is actually useful?

Here is how to perform a quick but thorough sanity check of your supersid.cfg:


🔍 Key sections to verify

1. Station identity (very important)

In [STATION] or [PARAMETERS]:

site_name = YOUR_STATION_NAME
monitor_id = YOUR_ID

✔ What to check:

  • site_name → something unique (e.g. LICHFIELD_LRO_1)
  • monitor_id → usually assigned by Stanford Solar Center

⚠️ Why it matters:

If this is wrong or missing, your uploaded data:

  • may not appear in the database
  • or could be misidentified

📡 2. Station list (signal sources)

stations = NAA, GQD, DHO

✔ What to check:

  • You’ve listed valid VLF transmitters
  • They are actually receivable in the UK

Good UK/Europe stations:

  • GQD (UK, 19.6 kHz)
  • DHO (Germany, 23.4 kHz)
  • HWU (France, 21.75 kHz)
  • NAA (USA, 24.0 kHz — sometimes weaker but usable)

⚠️ Common mistake:

Including stations you can’t actually receive → results in flat/noisy data uploads


🎚️ 3. Audio / input configuration

audio_sampling_rate = 44100

✔ Check:

  • Matches your sound card or SDR output
  • No clipping or saturation in your signal

If you’re using SDR (like your SDRplay setup), make sure:

  • audio is routed correctly into SuperSID
  • levels are not too high

⏱️ 4. UTC timing (critical)

utc_offset = 0

✔ Must be:

  • 0 for the UK (even during BST — SuperSID expects UTC)

⚠️ If wrong:

  • Your data timestamps will be incorrect
  • Uploads may still happen but become scientifically useless

📁 5. Data + logging paths

data_path = Data/
log_path = Logs/

✔ Check:

  • These folders exist
  • Files are actually being written daily

🌐 6. Upload settings (you already changed this)

automatic_upload = yes
ftp_server = sid-ftp.stanford.edu
ftp_directory = /incoming/SuperSID

✔ Confirm:

  • No typos
  • No extra spaces
  • Firewall allows FTP

📊 7. Sampling interval

log_interval = 5

Typical values:

  • 5 seconds (standard)
  • Don’t go too large or you’ll lose resolution

📉 8. Signal quality check (most important practical step)

Before trusting uploads:

  • Open SuperSID plot display
  • Look for:
    • Clear diurnal curve (day/night variation)
    • Sudden spikes during solar events
    • Low noise floor

Bad signs:

  • Flat line → no signal
  • Random noise → poor antenna or interference
  • Clipping → levels too high

📡 Given your setup (radio astronomy + SDR)

You’re in a great position to optimise this:

  • Your antenna should ideally be:
    • Long wire or loop tuned for VLF
  • Avoid:
    • Switching power supplies
    • Nearby digital noise sources

🧪 Final checklist

Before enabling uploads:

✔ Data files appear daily
✔ Signals show clear variation
✔ Station names are valid
✔ UTC timing is correct
✔ Internet working at midnight UTC
