Gaspar, EA6AMM

José Francisco de Almeida, CT4AN, IARUMS Coordinator from REP (Rede dos Emissores Portugueses; Portugal), informed that ANACOM (Portuguese Communications Authority) acts to eradicate interference and the abuse of several frequencies, including deeply protecting the amateur bands. https://www.anacom.pt/render.jsp?contentId=1713864

“ANACOM, the Portuguese National Authority for Communications, carried out a series of inspections with the Maritime Police, in an area between the ports of Caminha and Peniche. The actions in question aimed at verifying the status, operability and correct use of radiocommunications equipment installed on board vessels. In these actions, the most frequently detected violations or anomalies are related to the use of frequencies not authorized or not assigned to the maritime mobile service.

In 2021 last quarter, ANACOM carried out a series of inspections with the Portuguese Maritime Police, in an area between the ports of Caminha and Peniche. The actions in question aim to verify the status, operation and correct use of radiocommunications equipment installed on board vessels. If they are not working well or being used under the right conditions, or in the appropriate spectrum bands, they may interfere with other services and may make the correct operation of emergency communications unfeasible.
The actions were carried out in the ports of Póvoa de Varzim, Vila do Conde; Viana do Castelo; Caminha; Aveiro; Leixões; on the Douro River — Cais da Alfândega (Porto) and Cais da Lixa (Gondomar); and in Peniche.
In total, 20 vessels were checked, for coastal fishing, distant fishing, hotel ships and pleasure boats.

In these joint actions with the Maritime Police, the most frequently detected violations or anomalies are related to the use of frequencies not authorized or not assigned to the maritime mobile service. In some cases, non-certified equipment or equipment not suitable for use on vessels, as well as unauthorized radiocommunication encryption devices, were detected. In these actions, ANACOM carries out inspections on the equipment, and it is up to the Maritime Police to take the necessary measures.“

In the past, ANACOM operations such as this one lead to succesful actions.

Tad Cook, K7RA, Seattle, reports: Solar and geomagnetic activity increased this week. The average daily sunspot number was up by 52 points, rising from 42.4 to 94.4. The sunspot number peaked at 120 last Saturday, January 15.

Average daily solar flux went from 101.6 to 112, peaking at 119.4 on Sunday, January 16. Average daily planetary A index rose from 6.1 to 15.6, and average middle latitude numbers went from 4.1 to 11.3. On January 20, the daily solar flux dipped to 99.3, the first daily noon reading below 100 since January 6.

As reported by Spaceweather.com, sunspot AR2929 erupted at 1744 UTC on January 18 with an M1.5 class solar flare, blasting a pulse of X-rays causing a shortwave radio blackout. Another eruption occurred on January 20, producing a radio blackout.

I observed the January 18 blackout while using FT8 on 10 meters to observe propagation via pskreporter.info. Just before the blast, I could see my 10-meter signal reported by stations on the East Coast. Suddenly, I saw no reports. The surprising part: during that period, no local stations reported copying my signal either.

Predicted solar flux is 95, 93, and 91 on January 21 – 23; 89 on January 24 – 26; then 92 on January 27 – 28; 90 on January 29 – 30; 95 on January 31; then 100 and 105 on February 1 – 2; 110 on February 3 – 10; 115 on February 11 – 14; then 110, 108, and 106 on February 15 – 17; 102 on February 18 – 21; 100 on February 22 – 23; 95 on February 24, and 90 on February 25 – 26. Flux values may rise to 110 after March 2.

Predicted planetary A index is 8, 10, and 12 on January 21 – 23; 8 on January 24 – 26; 5 on January 27; 10 on January 28 – 30; 5 on January 31 – February 3; then 15 and 10 on February 4 – 5; 5 on February 6 – 9; then 12, 15, 12, 18, and 10 on February 10 – 14; 5 on February 15 – 19; 8 on February 20 – 22; 5 on February 23; 10 on February 24 – 26, then back to 5 through the end of the month.

These predicted values are updated daily.

Here’s the daily solar flux from Penticton, British Columbia, Canada. The local noon reading is the official SFN for the day.

This is the Weekly Commentary on the Sun, the Magnetosphere, and the Earth’s Ionosphere – January 20, 2022, from F.K. Janda, OK1HH:

“We have been able to observe four to eight groups of sunspots on the Sun over the past 7 days. They are now mostly in the western hemisphere, therefore solar flux has been declining. And suddenly a bang!

“This morning (January 20), we could observe a nice moderately sized solar flare near the northwestern limb of the solar disc. With a maximum at 0601 UTC, it caused the Dellinger effect in the Indian Ocean region for tens of minutes, followed by Type II and IV solar radio noise bursts, which confirmed the outburst of CME (but plasma cloud likely will miss Earth).

“Now we are facing a gradual decline in solar activity. Larger geomagnetic disturbances are expected in early February again. Their more accurate prediction will depend on the further development of the sunspot groups that are now located around the eastern limb of the solar disk.

“This is the geomagnetic activity forecast for January 21 – 27:

• Quiet: January 22 – 23
• Unsettled: January 21 – 22, 25 – 27
• Active: January 24 – 25
• Minor storm: January 24
• Major storm: 0
• Severe storm: 0

“Geomagnetic activity summary: After the last active and minor storm events (at the Budkov observatory, minor storm event were recorded on January 14, 16, 18, and 19) we expect decreased to unsettled geomagnetic activity January 21 – 22 or quiet to unsettled January 22 – 23. Then, starting on Monday, January 24, other active or minor storm events are possible. At the end of the current forecast period, we expect quiet to unsettled conditions to return.”

Here’s an interesting sunspot plot.

KA3JAW in Easton, Pennsylvania (FN20jq), reported:

“On Saturday, January 15, from 1346 to 1426 UTC, started hearing multiple central Mediterranean Sea stations, Italy, Greece, with others along the Adriatic Sea on SSB on 11 meters. Signal strengths deviated from fairly good to moderately strong with moderate QSB. Average distances reached up to 4X sporadic-e ranges at 4,750 miles. This was the time frame when the Global D-Region Absorption Predictions (D-RAP) maximum absorption attenuation reached up to 16 MHz. For the rest of the day Es conditions were dampened with higher amounts of skywave background noise.”

K7HBN (CN87) reported on January 14 via Western Washington DX Club:

“Today’s opening on 28 MHz was unique indeed. The opening was obviously enhanced by the solar wind stream from the coronal hole. What was the strangest, I heard stations from Arizona with a strong auroral component on their signals calling CQ on the same frequency as strong OH, SM, and LA stations. I can’t remember ever encountering such propagation in my entire time in ham radio, and I’ve orbited the Sun a few times.”

Dr. Tamitha Skov, WX6SWW, reports: “Our sun is getting busy.”

Sunspot numbers for January 13 – 19, were 111, 112, 120, 103, 99, 59, and 57, with a mean of 94.4. The 10.7-centimeter flux was 105.5, 110.2, 115.6, 119.4, 113.5, 114.5, and 105.3, with a mean of 112. Estimated planetary A indices were 3, 15, 22, 19, 9, 18, and 23, with a mean of 15.6. Middle latitude A index was 3, 10, 17, 16, 6, 12, and 15, with a mean of 11.3.

The post Tonga Volcano Update | Ham Radio Disaster Communications appeared first on QRZ NOW - Ham Radio News.

In amateur radio, the “QTH” Q-code means “What is your position?” when used as a question or “My position is…” when used as a statement. The Automatic Packet Reporting System® is a common avenue that amateur radio operators communicate their positions, among other useful information.

QTH.app is an APRS® client application exclusively for the macOS platform. It connects to the APRS network  via radio or Internet to help operators receive, transmit, and visualize information being shared over APRS.

MAJOR FEATURES

• Easy map navigation
• Supports connecting via:
  • Audio Modem – Use the internal Mac sound card
  • Serial KISS TNC
    • Special support for Mobilinkd Bluetooth TNCs
  • APRS-IS
  • AGWPE – exists, but buggy
• GPS Connections
  • Bluetooth GPS
  • Uses macOS Location Services in the absence of a GPS
• Support for drawing APRS shapes directly on the map
• Mapping APRS position reports, objects, etc
  • APRS symbols
  • Graphical display of speed and direction
  • Tactical callsigns
  • Station paths, including dead reckoning
  • Telemetry graphs
• APRS timeline
  • Go back in time and see where things were at a certain time
• Special weather station display, including wind barbs and temperature colors
• Location beaconing
  • SmartBeaconing
• Instant Messaging
  • Store favorite ham radio contacts in the Apple Contacts
• Alerts
  • Integrated with macOS notification center
  • Custom matching rules
• Logs packets to database
• Comprehensive help system
• Offline maps
• Other types of maps, topographical, OpenStreetMap, OpenCycleMaps, etc
• Map grids USNG/MGRS,  Maidenhead
• APRS Queries
• Simple digipeater support

PLANNED FEATURES

• Multilingual support – Supports English now. French later. Other languages as I have help.
• Spoken voice alerts
• Rig control for tuning to frequency objects
• Local data sharing with other QTH instances on LAN – Intended for operations rooms
• Search and Rescue features
• External API for integrations

WHAT IT WON’T DO

• Collect data from weather stations. Check out WeeWX for this.

PRICING

QTH.app follows a “freemium” pricing model. QTH.app is free to receive APRS traffic. The transmit functions require a software license. This serves a couple purposes: It allows verification that the person transmitting holds a valid amateur radio callsign and it puts a few dollars in my pocket. 

If you would like to purchase a license, please visit the store: QTH.app License

HamCation

A large ARRL team of member-volunteers, program representatives, and presenters will advance the convention theme inviting attendees to “reDiscover Radio” at Orlando HamCation, host of the 2022 ARRL National Convention February 10 – 13. A wide-ranging roster of workshops, exhibits, and activities will educate and entertain radio amateurs committed to developing knowledge and skills in radio technology and radio communication.

The convention will be held in two parts. On Thursday, February 10, an all-day ARRL National Convention Program will be held at the DoubleTree by Hilton Hotel Orlando at SeaWorld. Advance registration is required and includes a series of day-long ARRL Training Tracks and a National Convention luncheon. Registration can be completed online.

DX Engineering is the Official Sponsor of the 2022 ARRL National Convention Program.

On Friday, Saturday, and Sunday, February 11 – 13, HamCation will take place at the Central Florida Fairgrounds and Expo Park in Orlando — an 87-acre lakefront fairgrounds. The convention marks the 75th anniversary of HamCation — one of the largest, annual gatherings of radio amateurs in the US. HamCation tickets can be purchased online until January 31 and at the gate during the event.

The centerpiece of ARRL’s participation will be a large exhibit area in the East and West Hall. Nearly a dozen ARRL program areas will be represented, including Radiosport and DXCC Card Checking, Radio Clubs, the Amateur Radio Emergency Service®, Development, and the ARRL Foundation.

A suite of exhibits organized by the ARRL Education and Learning Department will include an introduction to the new ARRL Learning Center. ARRL Education and Learning Manager Steve Goodgame, K5ATA, will introduce this new member benefit that includes online courses, videos, and other amateur radio instruction and training. At another booth, ARRL Education and Technology Program Instructor Tommy Gober, N5DUX, will cover the ARRL Teachers Institute on Wireless Technology.

ARRL has invited several ham radio content creators from popular YouTube channels to meet and interact with attendees in the exhibit area. Josh Nass, KI6NAZ, of the popular “Ham Radio Crash Course” YouTube channel, will moderate. He is the 2020 winner of the ARRL Bill Leonard Award for outstanding published media that advances amateur radio. Visitors will have a chance to meet ARRL authors and editors.

ARRL Laboratory engineers and volunteers will offer free testing of visitors’ handheld radios. This service will determine the spectral purity of the output signal from their radios.

Members and other attendees can meet ARRL elected officials and Field Organization volunteers at the Southeastern Division booth to catch up on events and to explore opportunities to get involved through their ARRL Sections and radio clubs.

The exhibit area will also include the ARRL store and membership area, where visitors may join, renew, or extend ARRL and Diamond Club memberships and purchase publications, apparel, and 2022 Field Day products. New ARRL Membership Manager Matt Caruso will be eager to meet and greet members.

ARRL is sponsoring three forums at HamCation:

• An ARRL Emergency Communications Panel will be held at 3:15 PM Eastern on Friday. The panel will be moderated by ARRL Director of Emergency Management Josh Johnston, KE5MHV, and will include panelists from the ARRL Southeastern Division Field Organization.
• On Saturday at 2 PM Eastern, ARRL Collegiate Amateur Radio Advisors Andy Milluzzi, KK4LWR, and Tony Milluzzi, KD8RTT, will lead a Collegiate Amateur Radio Forum. The ARRL Collegiate Amateur Radio Initiative is a regular networking source among active campus radio clubs and their student members.
• An ARRL Membership Forum will be held on Saturday at 3:15 PM, moderated by Southeastern Division Director Mickey Baker, N4MB. This forum offers an opportunity to hear from ARRL representatives on key areas of member interest and amateur radio advocacy and to learn how ARRL supports dozens of ways to get involved and active on the air. Panelists will include President Rick Roderick, K5UR, and CEO David Minster, NA2AA.

Thursday’s Training Tracks at the DoubleTree Hotel are organized as all-day workshops led by experienced presenters. Four tracks being offered include Contest University (CTU), Emergency Communications Academy, Hands-On Handbook, and Technology Academy. Registration includes a seat at the National Convention Luncheon, which will feature a keynote address by David Minster.

Contest University will make its debut in the ARRL Southeastern Division. CTU Chairman Tim Duffy, K3LR, has organized the workshop with Teri Grizer, K8MNJ, assembling a team of experienced contesters as presenters and instructors. Presentations will include Fred Kleber, K9VV/NP2X, on “Contesting and Emergency Preparedness from the Caribbean;” Chris Blake, NX4N, and George Wagner, K5KG, on “Mobile QSO Party Contesting;” Luis Romero, W4LT, on “SSB Contest Audio Characteristics,” and Claudio Veroli, I4VEQ, on “World Radiosport Team Championship (WRTC) 2022/23.” Duffy will present “The Antenna Notebook.” Max Fountain, KJ4EUT, will offer a youth perspective, covering ways to use amateur radio contesting to attract more young people to amateur radio and retain them.

Emergency Communications Academy has been organized by ARES® Letter Editor Rick Palm, K1CE, and EmComm instructor Gordon Gibby, KX4Z. A panel of nationally recognized experts and trainers will conduct this workshop, which will cover current events, EmComm techniques, hardware, and software. Presenters include C. Matthew Curtin, KD8TTE; Helen Straughn, WC4FSU; Leland Gallup, AA3YB; Arc Thames, W4CPD; Christine Duez, K4KJN; Earl McDow, K4ZSW, and Jeff Capehart, W4UFL. ARRL staff, including Director of Emergency Management Josh Johnston, KE5MHV, and Field Services Manager Mike Walters, W8ZY, will be on hand.

Nass will lead the Hands-On Handbook Training Track. Presenters will take a deeper dive into a handful of popular amateur radio activities. Jason Johnston, KC5HWB, of the YouTube channel “Ham Radio 2.0” will present “Getting Started in Parks on the Air (POTA).” Additional presentations will feature Patrick Stoddard, WD9EWK, on “Amateur Satellites — Getting on the Air, and Operating from (almost) Anywhere;” Kyle Krieg, AA0Z, with “Intro to Remote Operating,” and Education and Technology Program Instructor Tommy Gober, N5DUX.

ARRL Pacific Division Director Kristen McIntyre, K6WX, will lead the Technology Academy. “Amateur radio is based on technology. The more we know about how things work, the more effective we can be as radio operators,” said McIntyre, who will also share a presentation about SWR. ARRL Lab Manager Ed Hare, W1RFI, will present “Compliance with the new RF-Exposure Rules,” covering the rules and recent changes by the FCC. Michelle Thompson, W5NYV, will present “Digital Communications Technology,” offering an understanding for how information travels over the air and how digital communication works. Joel Wilhite, KD6W, will present “Digital Amateur Television — A New Paradigm.” He will include a review of broadcast television technology being deployed into the US market, including ATSC 3.0 — Next Gen TV, and share opportunities that will influence the next generation of digital amateur television. Bob McGwier, N4HY, will present “ARDC Technical Projects and GEO/HEO Spacecraft Proposals,” discussing major projects supported by Amateur Radio Digital Communications (ARDC) to advance significant technical innovation in amateur radio.

The Orlando Amateur Radio Club sponsors Orlando HamCation. Hundreds of volunteers, including radio amateurs from radio clubs throughout the region, help support the event. Further details about the convention are available at www.arrl.org/expo and www.hamcation.com.
