Title: Objection filed against application for DRM SWBC license
Post by: ChrisSmolinski on April 23, 2021, 1203 UTC
Shortwave Solutions LLC filed an objection to the Application for International Broadcast Construction Permit (“Application”) by DPA Mac LLC (“DPA”). This is the DRM SWBC station application that appears to be an attempt to continue transmitting the real time financial trading data currently being sent under an Experimental Part 5 license.

The objection can be downloaded as a pdf file here:

With the changing of the guard at the commission, this may have the desired effect.  It is rather satisfying to read such roasting in legalese ;D

Maybe all the racket on 43 meters will go away soon, just in time for the coming of the new cycle.

Mmmmk. So one company doing shortwave data transmission for trading  is objecting to another's proposed solution. No surprise. Business rivalry.

Unrelated but this is from Shortwave Solutions website (bold added by me):

Quote
Out of stealth mode after successfully completing a second Chicago to Europe HF link for a private client, we are excited to extend our fully proprietary solution to additional geographies and offer better wireless connections for businesses in which every millisecond matters.
 
To that end, we have already taken initial steps to construct a Chicago to Tokyo HF link and a Chicago to Mumbai HF link, which is expected to be fully operational by October 2021. Critically, these links will offer target latency of 39.0 ms for Chicago to Tokyo and target latency of 49.0 ms for Chicago to Mumbai.

Were they really trying to cloak themselves? There had to be names associated with their existing projects.

I'd like to see what frequency/power/antenna combos they propose for the Chicago to Mumbai connection.  It would seem challenging (but not impossible) to do reliably even with the low SNR requirement they have.

This is just an educated guess on my part, but lots of start-up companies use the melodramatic term "stealth mode" to refer to the period of development prior to their first public press release. "Low profile" might be a better term. They certainly do not have any way to remain truly invisible, but they try to minimize public chatter by not discussing revealing info and by telling their employees, friends, and business partners "Hey! Keep your mouths shut until we tell you otherwise."
