ARRL Sacramento Valley Net
ARRL Sacramento Valley Net
On Thursday, September 15, 2022, ARRL Sacramento Valley Section will hold a Section Wide Net, first on the WD6AXM FM repeater atop Sutter Buttes near Yuba City on 146.085 MHz, plus 600 kHz offset, tone 127.3 Hz. Please wait for the call to the 2 meter ARRL Section Net after the 7 pm Yuba-Sutter ARES net has closed, usually around 7:20-7:30 pm Pacific Time.
For those who are unable to access the WD6AXM repeater, our 60m HF net will commence IMMEDIATELY after the VHF SV net signs off, on the 60 meter Channel 1 frequency of 5330.5 kHz USB. If we have no propagation on 60m, our alternate frequency is 3880 kHz LSB +/- 3 kHz. Those who check in to the VHF net are encouraged to join the HF net if they are able.
Important: If you do not hear net control over your radio, please check in anyway and listen for net control to acknowledge you via the Half Moon Bay WebSDR or the Northern Utah WebSDR.
All ARRL members, club presidents, Section appointees, and all appropriately licensed radio amateurs are encouraged to join us for the ARRL Sacramento Valley Section nets. Section News and items of regional and national interest to all radio amateurs will be the topics of discussion.
ARRL Sacramento Valley Section Wide Nets are conducted only on the third Thursday of such months as announced via official bulletin and on www.arrlsacvalley.org

Michael Joseph, KK6ZGB, Sacramento Valley SEC
Effective February 1, 2022, District 3 DEC Michael Joseph, KK6ZGB, will serve as ARRL Sacramento Valley Section Emergency Coordinator (SEC), taking over for our current SEC, Greg Kruckewitt, KG6SJT. I have interviewed Michael and am confident that he is qualified and motivated for this position. This leadership transition will be smooth as Greg will stay on as Assistant SEC. Congratulations to Michael on his new appointment and thanks to Greg for his many years of leadership and service to our community!
Dr. Carol Milazzo, KP4MD, ARRL Sacramento Valley Section Manager
Greg writes,
Michael has a strong background in emergency communications. He has worked in law enforcement, with the Red Cross, and the Sacramento Medical Reserve Corps. He has also served as the ARRL District 3 EC working closely with multiple counties.
I’m sure many of you already know Michael and have talked and interacted with him in the past few years. He has been working the Red Cross radio station during the major fires that we have experienced. He has handled this position admirably tracking teams and resources.
Michael is excited at the opportunity to inject new energy and enthusiasm into SV ARES. I’m looking forward to his leadership.
It has been my privilege to serve as the Sacramento Valley Section SEC and have the opportunity to work with each of you.
The Sacramento Valley Section ARES has accomplished so very much and performed at a high level supporting emergency communications. I’m proud that the various counties worked closely together and provided mutual support to each other during the fire seasons.
I’m not going away, but my focus with emergency communications will increase working to support the Winlink Development team. Many of the new technologies being integrated in Winlink will add the value of ARES operators to served agencies and Emergency Managers during times of crisis.
For an example of how Winlink is adding value to Emergency managers, check out this Dashboard that was developed by Oregon Office of Emergency Management for an exercise of integrating Winlink SPOTREP reports.
This is just their first try at this integration.

I trust that ARES ability to utilize Winlink will increase our value to our served agencies.
Anyway, exciting things are coming to emergency communication and I look forward to the opportunity to be involved.
I will work closely to support Michael in his new appointment.
I have no doubts Michael will offer your and your members great support and leadership.
Please feel free to email or call me any time if I can be of help to you.
Please reach out to Michael and welcome him!

FCC Updated Radio Frequency Exposure Rules Become Effective on May 3, 2021
from the ARRL News April 12, 2021
The FCC has announced that rule changes detailed in a lengthy 2019 Report and Order governing RF exposure standards go into effect on May 3, 2021. The new rules do not change existing RF exposure (RFE) limits but do require that stations in all services, including amateur radio, be evaluated against existing limits, unless they are exempted. For stations already in place, that evaluation must be completed by May 3, 2023. After May 3 of this year, any new station, or any existing station modified in a way that’s likely to change its RFE profile — such as different antenna or placement or greater power — will need to conduct an evaluation by the date of activation or change.
“In the RF Report and Order, the Commission anticipated that few parties would have to conduct reevaluations under the new rules and that such evaluations will be relatively straightforward,” the FCC said in an April 2 Public Notice. “It nevertheless adopted a 2-year period for parties to verify and ensure compliance under the new rules.”The Amateur Service is no longer categorically excluded from certain aspects of the rules, as amended, and licensees can no longer avoid performing an exposure assessment simply because they are transmitting below a given power level.
ARRL members can watch a recording of the May 15 webinar on RF Exposure rules on the ARRL Learning Network.

April 2021 Volunteer Monitor Program Report Released
from the ARRL News May 13, 2021
The Volunteer Monitor (VM) Program is a joint initiative between ARRL and FCC to enhance compliance in the Amateur Radio Service.
A General class renewal applicant withdrew his application after FCC notice that the renewal application would be held up pending review of Volunteer Monitor complaints. As a consequence, the Quakertown, Pennsylvania, applicant has no operating privileges.
Twenty-one operators in 14 states received Advisories because of their operation in the March CQ World Wide DX Contest. While making contacts with VC3T and VC2W, their LSB signals extended below 7.125 MHz, which is the lower limit of the 40-meter amateur phone band.
Volunteer Monitors participated in a nationwide training program on April 7 that was conducted by ARRL and the FCC.
The Volunteer Monitor Coordinator had two meetings in April with FCC Enforcement Bureau personnel.
The totals for VM monitoring in March were 1,394 hours on HF frequencies and 2,515 hours on VHF and above frequencies. -- Thanks to Volunteer Monitor Coordinator Riley Hollingsworth, K4ZDH

We could use some help with more of you participating as Net Control.
We have a dedicated, yet small, group of members who reliably perform these duties every single week. Sometimes, because of availability, our Net Control Operators handle our weekly Net more than once a month. It would be a big help if we could get more of you to join our Net Control ranks. And, I’ll make you a deal – you can participate as much or as little as you like if you at least give it a try.

Getting Your Amateur Radio License
Before you go on air, you need to be licensed and know the rules. In the United States the Federal Communications Commission (FCC) grants Amateur Radio licenses to individuals who successfully pass a multiple choice written exam at a Volunteer Exam (VE) session.
The FCC currently issues three levels of amateur radio license: Technician, General and Amateur Extra.
The license exam contains multiple choice questions selected from lists that are published online at http://www.arrl.org/question-pools. Many individuals prepare for an exam session using self-study license manuals and online practice exams. From time to time, license preparation courses are offered that cover the exam material over several weeks. "Ham-Cram" sessions are also popular, where a several hours' review class of exam questions and answers is immediately followed by a license exam session.

50 W PEP Maximum Power Limit Area on 70 cm
A little recognized portion of FCC Part 97 regulations applies to 420-450 MHz operations in most counties in our Sacramento Valley section:
47 CFR §97.313 (f) No station may transmit with a transmitter power exceeding 50 W PEP on the UHF 70 cm band from an area specified in footnote US270 to §2.106 of part 2. The indicated affected areas are specified in http://www.arrl.org/us270, in the State of California within a 240-kilometer (150 mile) radius around locations at Beale Air Force Base, California (latitude 39°08' North, longitude 121°21' West).
More information on the additional impact on 70 cm repeater stations is at http://www.narcc.org/NARCC-ARRL-PAVE-PAWS-Update-2014a.pdf
The Amateur Radio Service shares the 70 cm band on a secondary basis with the US Government which has priority. The US Department of Defense routinely monitors and locates signal sources on these frequencies. Our voluntary cooperation is mandatory to avoid interference with the Pave PAWS (Phased Array Warning System) radar at Beale AFB and thus to assure our continued access to these frequencies.
Radio Frequency Interference
posted February 3, 2018
ARRL and the FCC have a cooperative agreement in radio frequency interference matters. You may submit interference reports together with your supporting documentation to ARRL EMC Engineer Mike Gruber W1MG who then files the report with the FCC Gettysburg office.
You may also contact our Section Technical Coordinator Bob Wortman, WB6VYH for assistance. More information is posted under the "From the Section Manager" notes in the November 2016 Section News - Carol KP4MD
Bob Hess, W1RH, shares this helpful web page by NK7Z for identifying sources of Radio Frequency Interference http://www.nk7z.net/rfi-snapshots
Keep Our Digital Transmissions Legal on 60 Meters
Posted January 29, 2017
Interest in HF propagation phenomena and antennas has attracted increasing numbers of radio amateurs to operate CW and weak signal digital modes on our lower HF frequencies including 60 meters. The five frequency channels that US amateur radio operators share on a secondary basis with US federal government users on 60 meters (5 MHz) pose unique requirements for CW and digital operators. As explained on http://www.arrl.org/60m-channel-allocation, each US radio amateur emission on our 60m channels must be precisely centered in the center frequency of each assigned channel, that is, 5332.0, 5348.0, 5358.5, 5373.0 or 5405.0 kHz. Thus, for example, each CW or digital signal on channel 3 (USB Dial frequency 5357.0 kHz) must be precisely in the 5358.5 kHz channel center.
This may appear unreasonable to radio amateurs because a 2.8 kHz channel can accommodate many digital and CW transmissions simultaneously, and requiring multiple stations to operate on the same exact frequency would result in mutual interference. The National Telecommunications and Information Administration (NTIA)* explains this requirement in https://ecfsapi.fcc.gov/file/7021871884.pdf which states: "Allowing multiple emissions within the necessary bandwidth of the widest authorized modes (2.8 kHz) increases the possibility of harmful interference from secondary amateur stations to primary federal stations, and would make it more difficult for a federal station to identify an interfering amateur station. In addition, NTIA is concerned about the aggregate equivalent isotropically radiated power from multiple amateur stations transmitting within a single 2.8 kHz channel. Accordingly, NTIA requests that 47 C.F.R. Section 97.303(h) continue to require that amateur stations transmit only on the five center frequencies allocated to the amateur service." (See http://www.arrl.org/what-the-fcc-rules-say-97-303-h)
Observed Violations of US 60 Meter Frequency Regulations
FT8/JT65
This screenshot photo shows digital signals received on 60 meter Channel 3 (5357 kHz USB dial frequency) from 0300-0309 UTC on January 29, 2017. In the photo, the 5357 kHz dial frequency is at 0 Hz on the left side of the waterfall and the 5358.5 kHz channel center is at the 1500 Hz mark. Decodes of several US radio amateurs are seen transmitting digital emissions simultaneously on various frequencies throughout the channel 3 frequency range 5357-5360 kHz. This is the familiar appearance of a digital waterfall display on all other amateur radio bands; however, it violates the NTIA requirement that each US radio amateur transmission be on the 1500 Hz center mark (the 5358.5 kHz channel center frequency).
WSPR
The link http://wsprnet.org/olddb?band=60&sort=callsign&reverse=on&unique=on lists WSPR mode emissions on the 60 meter band. One can scroll down that list and see how many A, K, N and W call signs have been transmitting WSPR mode on 5288 kHz outside the authorized 60 meter center channel frequencies.
US WSPR transmissions continue to be observed on the WSPR software default 60 meter frequency of 5288 kHz, a completely unauthorized frequency for US radio amateurs.
Each licensee has the final responsibility for the lawful operation of his or her station. Unfortunately, the increasing automation in our radios has apparently accustomed some to falsely assume that the radio will correct for operator carelessness and ignorance of regulations. Our cooperation with NTIA requirements is essential for our continued access to the 60m channels and for possible future access to the new ITU worldwide 60 meter allocation at 5351.5 to 5366.5 kHz. (See http://www.arrl.org/news/view/arrl-asks-fcc-to-allocate-new-5-mhz-band-retain-channels-and-current-power-limit and http://www.arrl.org/news/fcc-invites-comments-on-arrl-petition-to-allocate-new-5-mhz-band). Please be aware of these requirements if you intend to or currently operate CW or digital modes on our shared 60m allocations. The ARRL Volunteer Monitor Program is documenting this matter and wishes to raise its awareness in the wider amateur radio community.
