Actually, the high speed traders are proposing HF broadcast. They will be providing actual content but do not need to sell advertising. They do have other uses for the signal that piggyback on the main programming. One can image the value they perceive. But that is in the broadcast bands. I have seen the planning, but they are not any kind of threat to amateur radio. The other proposed service isn't either I suspect, but I think we will see such service find its way into Public Safety Radio use for disasters. I do not know if SHARES uses such wider modes now. I attended a session in DC, I think it was, at an APCO annual conference where a maritime HF telephone interconnect service was peddling HF radio backup to county 911 systems for emergency use. I have not seen it get popular. It was only voice interconnect service. The name of the service provider escapes me. *Bob Famiglio, K3RF* On 1/25/2022 11:25 PM, Jairam, Ria, N2RJ (Dir, HD) wrote:
Hi Dave
You are absolutely correct that this isn't about the ham bands. In fact, some of this is defense related as well. FlexRadio and General Atomics are now using HF to control p.redator drones. It is a resiliency measure in case satellites are jammed or even destroyed.
The HF stock traders I know for a fact want to masquerade as international broadcasters and use DRM. The WIPE proposal is in several of the broadcast bands and they are trying to claim that they are a broadcaster.

There are many bands on HF besides the ham bands. R&S has been pitching this for years, and they are a leading supplier of HF equipment to militaries around the world and also to the aviation interests that use HF. With the decline of HF broadcasting, I haven’t seen any HF spectrum scarcity nor any move towards the ham bands. But of course it’s always possible. Even the fast-traders using experimental licenses seem to be looking outside the ham bands insofar as I can determine. And there are several HF broadcast applications pending at the FCC that seem a little suspect by their description of proposed service, so much so that the FCC staff is looking into them. But all this again is outside the HF ham bands.
“Wideband” reference probably is to wideband 4G ALE, a data mode that employs up to 48 kHz. The overall R&S description at this link may be useful, I’d guess that their presentation parallels some parts of this.

Of course, if anyone detects a suggestion or move toward our bands, do let me know! I keep watch and just haven’t seen anything and given propagation characteristics and international allocations the way they are, I think that this would be an uphill battle for anyone to wage in the immediate-to-intermediate future and unlikely given the existence of much easier HF pickings outside our bands. But sometimes things do happen.

A communications technology client in the state of Delaware just invited me to use their invitation, as their guest, to this ROHDE & SCHWARZ Webinar. I am going to attend. What caught my attention is the _HF Wideband_ reference. Here is an excerpt from the brochure and invitation. Perhaps some on this board already deals with this or is otherwise familiar. Not sure what this portends for amateur radio’s contributions to EmComm HF activities or even future spectrum threats:
/“We hereby invite you to our introductory webinar, “HF in a nutshell,” which covers currently available beyond-line-of-sight (BLOS) communications and focuses on high frequency (HF) communications./
/HF communications technology is reliable, proven and has been in service for decades. This webinar is the first in a series covering HF topics and will illustrate that HF communications is in no way your grandparents’ technology, but rather THE communications solution for the future. You will receive an overview of currently available BLOS communications solutions and the latest developments in this field, i.e. HF versus satellite communications (SATCOM) Rohde & Schwarz experts will highlight all the relevant benefits of HF, including robustness, capabilities and costs (CAPEX, OPEX). *_The webinar will be rounded off with an overview of HF wideband – a current development – and its pros and cons. “_*/
