I think this amateur radio related.  If the anonymous commenter wishes to join OSM and make amateur radio edits, a schema has been established (see URL below).  However, I'm not able to find a map product that makes use of the amateur radio data and don't think any of the typical OSM editors who read these notes are likely to take action on this feature of interest only to a niche community.
