Metadata Files

Metadata template for December 2021 Eclipse FestivalSNASH_dec_2021_eclipse_festival.xml




Download and install from the link above. 



1) Make sure Windows is set to use the audio channel from your radio as the default sound input.

2) Open SNASH from your Programs menu. 

3) Click "Select Configuration File" and browse to find the .XML file for the experiment you're participating in. (It is included in the zipped folder used for alpha testing, above.)

4) Make sure to fill in all the metadata fields! The following have special instructions:

  • Time Zone: Use the abbreviations in this table: (This is very important for analysis!)
  • ORCID: Sign up for an Open Researcher and Contributor ID at Keep track of your number - you may want to consider adding it to your page. This helps HamSCI keep track of contributions from citizen scientists.
  • Latitude and Longitude: For ease of processing, please be sure to use decimal format, not degree/minute/second! You can switch from one form to the other at
  • Callsign: If you have multiple radios collecting data, add a number after them, e.g., W8EDU-1, W8EDU-2, etc.

Also, keep in mind: 

  • Make sure to remove "e.g." in any fields where it's part of the default! This is a tool to make sure the metadata window is being filled out carefully. 
  • There may be multiple "pages" in the configuration window. Be sure to fill them all out so that your file saves properly. 

Tip: You may want to save a copy of this metadata file and change the default values according to your needs. (This is particularly useful so that you don't have to type in your latitude and longitude every time you want to stop and start the recording...)

Once you're happy with your metadata, select a location for your files to save. Start and stop the recording and confirm that the files (a) are saved in that location, and (b) playable. You can also use mediainfo's command line tool to verify that your metadata is saved properly.
