Hams try to re-carve the amateur radio spectrum in fight over open or encoded broadcasts
Radio enthusiasts argue signals must travel in the open, for the sake of national security
By Thomas Claburn in San Francisco 5 Apr 2019 at 07:30 47

Some people have been using ham radio frequencies for communication that's encrypted or difficult to decipher and others argue that's a threat to national security and a violation of the spirit and rules of amateur radio. Really, it's a fight over whether the amateur radio spectrum remains a hobbyist space or develops as a medium for data traffic.

In a letter [PDF] (https://ecfsapi.fcc.gov/file/1040322516387/FCC%20Letter%20RM%2011831%20final.pdf) submitted earlier this week to the US Federal Communications Commission, NYU professor Theodore Rappaport, who runs the NYU Wireless research center at the NYU Tandon School of Engineering, voiced support for RM-11831 [PDF], a proposed radio rule revision that, among other things, would require radio transmissions be open to public scrutiny.

"RM-11831 allows ACDS [Automatically Controlled Digital Stations] to continue to operate in ham radio, but simply requires them to use openly decodable transmissions in compliance with FCC rules," Rappaport says.

That means difficult-to-decipher, proprietary automatic repeat query (ARQ) traffic, using radio signal modulation modes like Pactor 3, WINMOR, STANAG, and ARDOP would have to be open source or make easy decoding available to ham radio operators who wish to examine the traffic.

Federal rules ban amateur radio stations from transmitting "messages encoded for the purpose of obscuring their meaning," with some exceptions. Despite this, evolving technology has given rise to a number of services that, some argue, violate these rules, such as Winlink and D-Star.

If the rule change is adopted, it might mean the end of these services, or reduced functionality, and might make it harder for innovative services like New Packet Radio to emerge.

RM-1183, argues Rappaport, "assures national security by providing transparency and self-monitoring by the public of all amateur radio transmissions in the HF spectrum that routinely cross international borders."

At the same time, Rappaport urges the FCC to reject other proposed rules, NPRM 16-239, RM-11828, RM-11759, and RM-11708, that he claims would allow more obscure or effectively encrypted communications over public radio spectrum.

Others offering their opinions to the FCC disagree. "RM-11831 is yet another effort by a small circle of US amateur radio operators wanting to cripple the use of data modes on the amateur radio bands," writes Stephen Williams of Bakersville, North Carolina, in a comment submitted to the agency.

"If enacted, the changes proposed will NOT promote transparency and will NOT prevent the use of the bands by commercial interests. There are no proven cases of commercial use of modes like Pactor on the amateur bands. This RM-11831 effort is simply an attempt to kill the use of Pactor in the US as a communications mode supporting emergency communications operations."

In a letter [PDF] to FCC chairman Ajit Pai last December, Loring Kutchins, president of the Amateur Radio Safety Foundation (ARSL), which oversees Winlink, pushed back against Rappaport's characterization of the service.

"Theodore Rappaport and the opponents he informs offer an emotional, layman's conjecture in their assertions that hard-to-monitor, advanced digital protocols used in the amateur radio service will encourage crime, terrorism, and are a threat to national security," said Kutchins. "They clearly do not know or appreciate what monitoring and inspection routinely occurs, and are thus not qualified to judge."

Kutchins claims Winlink sysops inspect system traffic. "All communications are logged in detail and messages are archived, and available to the FCC and anyone else on request," he insists, pointing to a separate set of comments intended to rebut Rappaport's claims.

Dan White, of Granbury, Texas, is both an ARSL member and critic. He claims the organization is backing proposed rules like RM-11708 "to provide free encrypted email and bypass commercial maritime services under the guise of 'emergency communications' while exhibiting total disregard for incumbent spectrum users."

The FCC will consider input on RM-11831 until April 29 this year. ®

Field Day Training

DrZ1953
 
Edited

Don KI4D - FD Chairman / Alexandria Club Sent Plans for F.D. training sessions on ALL Modes being used. ie. that includes Digital. His text is as follows! Note Locations and times of practice and class. Computer logging will be used.

Don's email is: don.ki4d@...

One new area for emphasis this year will be digital mode operations, meaning computer generated digital communications. If we have a sufficient number of skilled operators for digital modes, digital mode stations will be added
to our Field Day line-up for the first time. As you know the ARRL awards 2
points for each digital mode contact during Field Day, something we have not taken full advantage of in the past. During this period of relatively poor HF propagation, digital modes offer the best promise for contacts because they are far less affected by noise levels. Taking advantage of this with a strong digital modes capability could improve our Field Day performance.
For improved performances on Field Day and for potential benefits to emergency services, amateur radio clubs across the U.S. are increasingly using digital modes during Field Day.



To offer an opportunity for club members to demonstrate proficiency in digital mode operations, I am proposing that we set up 3 Field Day digital stations as follows: (1). VHF/UHF/Satellite - SSB/FM/Dig; (2). 80/40 - Dig; and (3). 10/15/20 - Dig. To support such a capability, first and foremost, we need more operators with experience using digital modes.



To strengthen club digital modes capabilities, I am proposing we conduct digital modes practice operating sessions during April and May. Weather permitting, plans are to conduct these sessions on Sunday mornings from April 17th thru May 5th from 8:00 a.m. to 11:30 a.m. at Jefferson Manor Park, 2909 Farmington Drive Alexandria, VA. More sessions will be added if needed. These sessions will involve use of FLDigi and WSJT-X software, see attached file FLDigi with PSK31 for Field Day. Those with proficiency in digital modes are highly encouraged to attend as mentors and operators; however, this effort is mainly aimed at relatively new hams who may not have HF privileges or the equipment, but want to get involved in Field Day HF operations. Those attending the sessions do not need to bring their own ham gear, but they do need to bring chairs and writing materials. Those with FCC Technician Licenses are welcome because a control operator with all privileges will be present at all sessions. Please send me an email letting me know if you are interested in "digital crew" participation by March 30th.
This will help me gauge the size of the effort, and how to organize and
supply the ham radio gear needed for practice sessions.



Another new area of emphasis this year will be increasing opportunities for "hands-on" operating time for all participants. The goal is not only to draw maximum attendance and interest, but to keep those in attendance busy around the clock. This will be achieved by conducting a sign-up for operators. In addition to ARC members, Arlington Radio Club members will join us again this year for Field Day. Just recently I was told by a member of the Arlington club that they look forward to being scheduled for operator duties, even after midnight.



To make Field Day 2019 successful with these new efforts, strong volunteer support from club members is essential. Your help and ideas are needed in many areas from planning to execution of the event. Thanks in advance for your cooperation and support.

Rande,

Thanks for volunteering! April 30 is tomorrow. Probably we should
discuss the Net Control Station job and technical requirements at a
brunch. I'll plan on being NCS tomorrow, because no one else has
volunteered. Future fifth Tuesdays this year will be: July 30, October
29, and December 31 (yes, New Year's Eve, and also Straight Key Night).
Which of those dates would you like to be NCS? You may reply to me off-

Sabertooth Antenna

Benn Kobb
 

The patent holders on the Sabertooth wire antenna design have got a manufacturing deal.

Their announcement for the first model (160-6m in a 59 foot dipole) contains no web address and I can't attach the ad to this post.

If you are on Facebook however their page is:

https://www.facebook.com/sabertoothwire/

If you are not familiar with this innovation, it essentially uses sharp angles in the dipole to reduce size and obtain various other benefits. There is no tension on the radiating elements. I am looking for a version I could fit in the 12 or 15 foot wide apartment balcony. They have disclosed the entire invention and history of experiments in detail.
