Going the Distance! 1BTC Uses HF Radio to Go Far and Wide

FORT DRUM, New York (May 3, 2018)–Captain Luke Reese, commander of C Company, 7th Brigade Engineer Battalion, 1st Brigade Combat Team, 10th Mountain Division (LI), successfully transmitted a 300-mile high frequency voice and data radio check to West Point while spearheading a new program to boost tactical communications from Fort Drum. Maj. Gen. John Baker, Commanding General, U.S. Army Network Enterprise Technology Command, observed the radio check from West Point.

In an effort to renew some looked-over radio options, Reese opened the possibility of HF long-range capabilities.

“This is something we’ve been working on,” said Reese. “Dusting off some of this old equipment that hasn’t been used in years and use it as a relevant back-up plan.”

Leveraging high frequency is a skill that hasn’t been prioritized in the Army in recent years. The Army uses frequency modulation and ultra-high frequency tactical satellite, which have benefits, but are also limited.

“HF presents some challenges because making this network functional requires some level of experience… there’s really an art to it,” said Maj. Craig Starn, 1BCT S6 officer-in-charge. “The major benefit is it provides unlimited range with zero cost or resources required and no lead time is required to use the system.”

Reece’s efforts in HF strives to enhance the Army’s ability to maintain mission command while extending the brigade’s, or any unit’s, operational reach.

This weekend: Historic NSS Call Sign reactivated during Armed Forces Day Crossband Test

100th Anniversary QSL card for NSS

Many thanks to SWLing Post contributor, Brian Smith (W9IND), who shares the following press release regarding the historic U.S. Navy callsign NSS that will be reactivated during the 100th anniversary of the former Naval Radio Station in Annapolis, Maryland:

Historic NSS Call Sign to be Reactivated During its 100th Anniversary

Historic U.S. Navy callsign NSS will be reactivated during the 100th anniversary of the former Naval Radio Station in Annapolis, Maryland.  The U.S. Naval Academy Radio Club (W3ADO) and the Potomac Valley Radio Club (W3GRF) will reactivate the historic callsign during the upcoming Armed Forces Day Crossband Military/Amateur Radio Communications Test.

NSS operations from the location of the former Naval Radio Station on Greenbury Point will be from 1300Z Saturday May 12 to 0200Z May 13.  CW and SSB transmissions will be on 4038.5, 5330.5, 7533.5, 9447, 14487 and 17545 kHz.  NSS will listen for callers on announced frequencies in adjacent amateur bands.  Commemorative QSLs will be sent for all QSOs.

NSS began operations in 1918 as the Annapolis High Power Radio Station using a pair of Federal Telegraph Company 500 kilowatt Poulson Arc transmitters and four 600 foot towers operating in the Very Low Frequency (VLF) band.  At that time VLF provided the only known capability for trans-oceanic radio communications. NSS began continuous operations in the HF bands about ten years later until 1976 when its HF mission was transferred to Naval Radio Station NAM in Norfolk, Virginia.  The 1200 foot central tower and dozens of other towers and masts were demolished in 1999, except for three iconic 600 foot Eiffel towers that remain at the southern tip of Greenbury Point.

Many thanks for sharing this item, Brian!  I will do my best to snag a few stations during the crossband test tomorrow!

Eric Swartz (WA6HHQ) on Ham Radio Workbench

Leave a reply

Many thanks to SWLing Post contributor, Eric McFadden (WD8RIF), who notes that Elecraft co-founder, Eric Swartz (WA6HHQ), is featured on the latest episode of Ham Radio Workbench. Here’s the description of the interview provided by Ham Radio Workbench:

Eric Swartz WA6HHQ, co-founder of Elecraft, joins us to guide our understanding of RF receiver performance specifications. Eric introduces us to common receiver specs such as Sensitivity, Noise Floor, Dynamic Range, Intermod Dynamic Range, Phase Noise, and RMDR. He tells us what they mean in real-world receiver performance terms, how they are tested, and whether it’s better to have a higher or lower number in each one.

Eric’s interview starts around 1 hour 9 minutes into the show:

Pirate Radio Bill Formally Introduced

Bipartisan legislation designed to thwart and penalize radio pirates and supporters

BY SUSAN ASHWORTH, MAY 9, 2018

Another legislative step has been taken in the effort to fight illegal pirate radio operations.

On May 8, Rep. Leonard Lance (R-NJ) and Rep. Paul Tonko (D-NY) formally introduced a bill to Congress designed to thwart and penalize illegal radio operations.

Known as the ‘‘Preventing Illegal Radio Abuse Through Enforcement Act,” the PIRATE Act will increase the ability of the Federal Communications Commission to crack down on pirate activity by increasing fines, streamlining enforcement and placing liability those who facilitate illegal radio broadcasts.

“It is time to take these pirates off the air by hiking the penalties and working with the Federal Communications Commission on enforcement,” Lance said in a statement. Chairman Pai and Commissioner O’Rielly have been able partners in making sure these broadcasts are stopped. This bill will give the FCC even more tools to take down these illegal broadcasts.”

As a commissioner who has long been searching for more Congressional authority to address pirate radio operations, FCC Commissioner Michael O’Rielly commended the effort after the news was announced.

“This bill rightfully increases the penalties, requires regular enforcement sweeps, and augments the tools available to the commission, which are woefully inadequate and outdated, to deal with illegal pirate broadcasters,” O’Rielly said in a statement.[…]

Mystery: Traders using “shortwave to cross oceans with less latency than any fiber”

Many thanks to SWLing Post contributor, London Shortwave, who shares this fascinating article which takes a look at high-frequency trading firms:

Shortwave Trading | Part I | the West Chicago Tower Mystery

Since 2014 this blog has extensively covered the wireless networks built by high-frequency trading (HFT) firms or network providers to reduce latencies between the different exchanges around the world (market makers need fast connectivity to manage risk, news traders also need to be fast, etc.). This epic investigation on microwave, which started with HFT in my backyard, will be fully reported in a book I’m currently writing (in French for now). As I’m quite busy with this writing (and other/more interesting matters about market structure), I didn’t really have the time to check out what I have been hearing about “shortwave” or “high frequency” radio. This is the way high-frequency trading firms may use shortwave radio to directly connect widely-separated locations (in short, traders are willing to use shortwave to cross oceans with less latency than any fiber – like Hibernia).

But recently I got more intel about the situation (and some fun anecdotes). With some help from the US, I found that a firm purchased a field for more than 1$M to build towers and antennas; with some help from the EU, I got hints about Germany; and I dug into UK public records. I even met, last March in Amsterdam, people involved in those projects. Not surprisingly, at least five HFT/market making firms showed up behind the shell companies/names they use to hide. The usual suspects. Above all, I have been contacted recently by someone from Chicago, Bob, who decided to investigate the “shortwave” networks in his backyard. Today I’m pleased to host Bob as a new guest writer on this blog. This first part of the “Shortwave Trading” series is released at the same time Bob is talking about what he found at the STAC Summit in Chicago. Next parts will follow soon.[…]

Read the full guest post by Bob (KE9YQ) at the blog Sniper in Mahwah & Friends.

This is a fascinating read, and it’s fun to follow Bob–who obviously knows his way around communications sites and the FCC–put all of the pieces together. I’m looking forward to his future posts.

I think it’s fascinating that while some are calling the HF/shortwave spectrum a dead, outdated medium, others are working in the background leveraging shortwave’s strong and unique properties as a communications medium:

  • Shortwave requires no infrastructure between communication points
  • Shortwave can be used to communicate over vast distances
  • Shortwave needs no permission to cross borders
  • Shortwave has no latency–signals/communications travel at the speed of light
  • Shortwave communications are relatively durable, adaptive and are difficult/costly to intentionally block

As I’ve mentioned a number of times in the past–especially in this article from almost four years ago–while we may be seeing big government broadcasts sun-setting we haven’t seen the end of shortwave communications.
