There are stock trading transmitters in large USA cities operating from 60-80GHz. Some hams are already concerned with the interference possibilities there.A proposal by the Shortwave Modernization Coalition is wanting to allow for “non-voice” transmissions from 2-25MHz. Seems suspicious, could be the stock traders. If it isn’t the stock traders, then still, why the proposal in the first place?https://docs.fcc.gov/public/attachments/DOC-394830A1.pdf
