UPDATE 10/2018 – ARRL

Florida ARES Teams Handle Hurricane Duty

Fri, 10/12/2018 - 5:09pm
 ARES Teams Handle Hurricane

Over the past week, Amateur Radio Emergency Service® (ARES®) teams in the ARRL Northern Florida Section went on alert and some activated to support emergency communication before and during Hurricane Michael.

Miller Norton, W4EMN, the Communications Watch Officer at the Duval County Emergency Operations Center (EOC) in Jacksonville, Florida, was monitoring SARnet — a UHF-linked repeater network in Florida — when he heard an urgent call for help that needed to be sent to the State EOC in Tallahassee. All other forms of communication were out, but Norton was able to relay the message to via Amateur Radio. He also passed along messages and requests from the Jackson County EOC to the American Red Cross. Norton said officials in Tallahassee and Jackson County were both “incredibly grateful” for the way the SARnet system functioned during the weather emergency.

Jackson County Emergency Coordinator Ricky Whittington, KD4AST, deployed to the county EOC in Marianna.

“We took a direct hit by the center of the storm at 140 MPH,” he told Clay County ARES Assistant Emergency Coordinator (AEC) and Public Information Officer Scott Roberts, KK4ECR. “[The] county maintenance building across the road from the EOC was picked up and slammed into the north side and over the roof of the EOC just prior to the eye passing over.”

The incident took out the HF antenna, which has since been restored. Whittington said the internet failed, as did cell service for a while. Hams have been passing material and resource orders to the State EOC via HF and SARnet.

Whittington reported “total devastation of Bay, Jackson, and Gulf counties,” with loss of electrical power and water service, in addition to damage in Franklin, Holmes, and Leon counties. “[The] only mode of communications after the eye came across was ham radio, until we got minimal cell service a few hours ago,” he reported on October 11.

 

(adsbygoogle = window.adsbygoogle || []).push({});

ARES teams in other counties reported activations, although some teams remained in monitoring mode.

  • Escambia County ARES activated on October 9 at 2300 CDT to support two shelters — special needs and pet-friendly — until they closed on October 10 at 1700 CDT
  • Although the Alachua County EOC activated at Level I, the ARES volunteers never activated beyond Level 3. However, AEC Susan Halbert, KG4VWI, spent a day at the EOC coordinating with emergency managers in case they needed to open a shelter for local evacuees or for host county operation. No hams were needed for shelters, but one or two shelters opened for outside evacuees.
  • The Gilchrist County EOC activated at Level 2 and shelters opened. The local 2-meter repeater was excellent, and no power outages were reported. ARES primarily remained at Level 3 in monitoring mode. Daily nets were held for hurricane weather briefings and the Northern Florida Section Emergency Net on HF was able to provide up-to-date storm location information to the State EOC when it lost internet service.
  • Citrus County ARES was called to activate on Monday, October 9, at 5 PM CDT. At that time, emergency managers had opened four shelters, serving 38 clients (and 13 pets). Telephone and internet service remained operational throughout the weather event, although ARES volunteers staffed two shelters on a precautionary basis, as well as the EOC at activation. All shelters closed by 6 AM on Wednesday, October 11. Citrus County ARES volunteers covered two back-to-back 12-hour shifts at the EOC. ARES personnel stood down at 6 PM on Tuesday, October 10.
  • Duval County activated to Level 3 monitoring status along with the activation of the Duval County EOC. No shelters opened in Duval County, and there were no reports of serious damage.
  • Clay County also activated to Level 3 monitoring, when two tornadoes touched down in the county. No shelters were opened, and no official activations were requested.

N1MM- I/Q input to Spectrum Window – Ham Radio Logging

Fri, 10/12/2018 - 2:03pm
N1MM – Ham radio contest logging N1MM Logger is the world’s most popular ham radio contest logging program. For CW, phone and digital modes, its combination of contest-optimized features is unmatched.

I/Q input to Spectrum Window. I have an experimental version of the program posted in the Experimental gallery. It supports I/Q input. It has been tested with Airspy HF+, SDRPlay RSP1 and RSP2 and the IC-7610 successfully. Tests with an Elad radio were not successful. I am interested in what other SDRs people have that provide I/Q output that they would like to have supported. I am not interested in trying to support $20 dongles, I only want to support SDRs that are actually useful for contesting. Post below what SDR you have that has I/Q output. Please do not post non-SDR radios.hAM rADIO

IMPORTANT: The radio *must* have an ExtIO.dll provided by the vendor! Sound card output is NOT sufficient

Reported Russian Ham Band Intruders Continue to be Troublesome

Thu, 10/11/2018 - 2:32pm
Ham Band Intruders Ham Band Intruders

The International Amateur Radio Union Monitoring Service (IARUMS) reports interference on 40 meters from various Russian sources. The Russian coastal over-the-horizon (OTH) radar “Sunflower” was very active on 40 meters and audible in Europe in the evenings, transmitting FM on pulse. The site is believed to be northeast of Vladivostok. IARUMS Region 1 Coordinator Wolf Hadel, DK2OM, said it was monitored in September.

(adsbygoogle = window.adsbygoogle || []).push({});

In addition, a Russian ship was observed transmitted on 7,110 kHz on F1B with 50 baud and 200 Hz shift. The vessel was believed to be in the area around and east of Cyprus, on the air daily in September running F1B with 50 baud and 200 Hz shift. Another Russian ship was heard on September 18 transmitting AT3004D with 12 × 120 baud PSK2A on 7,179 kHz with a 2.6 kHz bandwidth in the area of Crete. And a Russian military system, believed to be near Moscow, was heard transmitting on 7,198 kHz in AT3004D test mode.

Elsewhere fishing crews often were monitored on 3,500, 3,535, 3,540, 3,560, 3,585, 3,590, 7,000 kHz, and 14,320 USB.

USB micro KEYER III – MicroHam

Sun, 10/07/2018 - 2:06pm

 

MicroHam

micro KEYER III is the world first and the only amateur radio USB interface featuring high dynamic range, 24-bit audio processing chain on all signal stages. It is the most powerful single radio All-In-One USB interface and the only USB interface to fully support digital and voice operation including microphone switching in one box.

With a single USB port, micro KEYER III works with any Windows-based logging or control program for CW, Voice, FSK and Digital operation (RTTY, FT8, WSJT, PSK31, SSTV, etc.).

micro KEYER III includes a CAT, radio control interface that supports all common standards A(RS-232, CI-V, Kenwood and Yaesu TTL), a powerful CW memory keyer using genuine K1EL’s WinKey, a Digital Voice Keyer for SSB, two channel audio processing for transceivers with dual receivers, automatic microphone selection, and a buffer/sequencer for amplifier or LNA control.

Compared to 16-bit audio interfaces, or to any USB enabled transceiver, including flagship transceivers from well known manufacturers (as of autumn 2018), unique 24-bit USB audio processing in the micro KEYER III provides advantage in higher dynamic range (>105dB), preserving transceiver performance also for audio processing on computer (digital modes), otherwise limited by 16-bit USB audio signal chain.

INRAD W1 competition headset

Sun, 10/07/2018 - 1:23pm
INRAD W1

*Photo N6MJ

New for 2018:  The INRAD W1 competition headset.  Following the successful introduction of the INRAD Desk Microphone System in 2017 and its excellent reviews from both the ham community at large and the ARRL‘s QST Product Review, we introduce this new unique headset for DXing, contesting, or general use on the air. 

THE INRAD W1

Ham radio never sounded so good!

  • Comfortable over-the-ear earpieces with large diaphragm high response speakers

  • Full stereo reception to allow use with dual receiver transceivers

  • 600 ohm dynamic microphone element on adjustable long boom with the best sounding headset transmit audio in ham radio

  • Unique headband tilt-back feature as used on pro broadcast headsets.

  • Extra wide and thick rubberized foam top padding for long stretches of wearing the headset while DXing or contesting

  • Light: weighs only 13 ounces. Avoid the neck and head fatigue associated with modified aircraft headsets sold by other companies.

  • Extra long straight + coiled cable with total length of almost 7 feet. 4 ½ feet straight + 1 ½ feet coiled + 1 ft straight. Coiled section can be stretched out an additional 2 feet if desired.

  • Rig mic jack adapters available for 8 pin modern Icom rigs, 8 pin Yaesu / Ten-Tec, 8 pin Kenwood / Elecraft, RJ-45 Yaesu, 3 pin TRS FlexRadio 6400/6600.

amzn_assoc_placement = "adunit0"; amzn_assoc_enable_interest_ads = "true"; amzn_assoc_tracking_id = "qn0c-20"; amzn_assoc_ad_mode = "auto"; amzn_assoc_ad_type = "smart"; amzn_assoc_marketplace = "amazon"; amzn_assoc_region = "US"; amzn_assoc_linkid = "4969cf2edaec6bf602678d298f572f59";

The right features for long hours of radio communication use.  

           Starting with comfortable over-the-ear earpieces.  Your ear goes inside the cup rather than having

earphone

    padding pushing your ear backward against the head, leading to pain after hours of use.  Headband fatigue is another potential problem with long-term headset use.  Modified aircraft headsets sold by others for ham radio use push down on the top of the head because they are heavy and lack adequate padding at the top.  We have solved this problem with two features.  First, thick rubberized foam padding at the top of the headband that molds to the head when in use.  Second, like broadcast headsets, the W1 has a tilt-and-click headband tilt feature.  The headband can be tipped back as far as 30 degrees off vertical without moving the earpieces, in addition to standard up/down movement of the band.
           Receive and transmit audio sound terrific.  Large diaphragm high response speakers provide clear, clean articulation of receive audio.  Stereo connector for use with dual receive transceivers if desired.  Transmit audio is from a 600 ohm dynamic microphone element that’s the correct impedance for your

HF transceiver

    and has excellent response from 50 Hz-15 kHz.   Sounds great for DXing, contesting, and general on-the-air use.
         Extra long straight and coiled cable from the headset to the radio.  7 feet total length.  4 feet of straight section, followed by 1 1/2 feet coiled for RF suppression, then 1 foot straight to the adapter for the radio mic jack.  Connect the 1/8″ mono transmit audio jack on the headset to an INRAD M-series mic jack adapter and you’re ready to operate.

The right price and the right customer service.

         Headsets are not treated gently.  They are a tool, and tools are made to be used.  Rough handling means headsets have to be well-built to stand up to it, and that the manufacturer will stand behind them also.  We offer a 1 year unconditional warranty for parts and labor.  We will repair or replace your headset at our option.  You only pay the shipping cost to send it to us.
             All the features you need in an

Amateur Radio headset

    • , plus the customer service and warranty to back it are available at the excellent price of only

 $179 plus shipping

    • .  M-series headset mic jack adapters, sold separately, are $14.95.

W1 is in stock and now shipping!

      The W1-B mic boom mic kit only and W1-E element only to be available later in October.

Investigation into International Space Station Leak Continues

Fri, 10/05/2018 - 1:14pm
International Space Station Leak

NASA has issued a statement regarding a leak affecting the International Space Station (ISS). On August 29, a mysterious 2-millimeter hole was discovered on a Soyuz capsule docked to the ISS, resulting in a pressure leak.

The Soyuz capsule last carried to the ISS cosmonaut Sergey Prokopyev, and astronauts Serena Auñón-Chancellor, KG5TMT, and Alexander Gerst, KF5ONO. It is scheduled to return them to Earth in December.

The hole, which appeared to have been drilled, was repaired by the crew. Roscosmos said this week that the hole was not drilled by accident, opening the possibility of sabotage. Roscosmos Director General Dmitry Rogozin earlier ruled out a manufacturing defect.

 

“[This] indicates that this is an isolated issue which does not categorically affect future production,” the NASA statement said. “This conclusion does not necessarily mean the hole was created intentionally or with mal-intent.”

Roscosmos has claimed the hole may have been drilled by a technician on the ground.

NASA and Roscosmos continue to investigate the incident to determine the cause, and a November spacewalk is planned in order to gather more information.

On October 11, US Astronaut Nick Hague, KG5TMV, and Russian Cosmonaut Aleksey Ovchinin will head to the ISS aboard a Russian Soyuz MS-10 spacecraft. NASA Administrator Jim Bridenstine is scheduled to attend the launch and plans to meet with Rogozin at that time.

The K7RA Solar Update – 10/05/2018

Fri, 10/05/2018 - 11:08am
Sunspots

Sunspots finally returned on September 29, after over two weeks with none.

Average daily sunspot numbers increased from 0 to 9.6, and average daily solar flux increased from 67.9 to 68.4 over the past week, September 27 through October 3.

Average daily planetary A index declined from 10.9 to 7.7, while average mid-latitude A index changed from 7.9 to 6.1.

Predicted solar flux is 68 on October 5-18, 70 on October 19 through November 2, 68 on November 3-14, and 70 on November 15-18.

Predicted planetary A index is 5 on October 5-6, 20 on October 7-8, 12 on October 9-10, then 10, 8, 5, 12 and 8 on October 11-15, 5 on October 16-17, then 10, 25, 14, 8 and 12 on October 18-22, 8 on October 23-25, then 10, 6, 12, 8 and 5 on October 26-30, then 8 on October 31 through November 2, then 20, 35, 10, 18 and 15 on November 3-7, then 8, 5, 10, 8 and 5 on November 8-12, and 5, 10, 25, 15, 8 and 12 on November 13-18.

 

Geomagnetic activity forecast for the period October 05-31, 2018 from F.K Janda, OK1HH.

Geomagnetic field will be:

Quiet on October 15-16, 29-30

Quiet to unsettled on October 12, 14, 27, 31

Quiet to active on October 5, 10-11, 20, 22-26

Unsettled to active on October 6, 9, 17, 28

Active to disturbed on October 7-8, 13, 18-19, 21

Solar wind will intensify on October 7-9, 11-13, 18-20, (27-28)

From Australia’s Space Weather Services:

SWS GEOMAGNETIC DISTURBANCE WARNING 18/22 ISSUED AT 0417 UTC/05 OCTOBER 2018 BY THE AUSTRALIAN SPACE FORECAST CENTRE.

Geomagnetic activity is expected to increase to active levels on UTC day 7 Oct and to minor storm levels on 8 Oct. There is a remote chance that for short periods the geomagnetic activity may even reach major storm levels during this interval.

The disturbance is due to the expected arrival of CIR (Corotating Interaction Regions) and HSS (High Speed Streams) associated with a large recurrent positive polarity north polar connected coronal hole. The aurora may be visible on the local nights of the 7 and 8 October from Tasmania, coastline of Victoria and Southwest coast of Western Australia.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED DUE TO CORONAL HOLE HIGH SPEED WIND STREAM FROM 07-09 OCTOBER 2018

GEOMAGNETIC ACTIVITY FORECAST

07 Oct:  Active

08 Oct:  Minor Storm

09 Oct:  Active

Following the recent temporary shutdown of the solar observatory in Sunspot, New Mexico, the local newspaper in Alamogordo ran this article by local astronomer Alan Hale, explaining some solar physics:https://bit.ly/2zQlwR0

 

Ted Leaf, K6HI, had a comment about the K9SQG 40-meter observations last week. “Forty meters may be dead for DX, but not for NVIS. We have a daily 40m net at 4pm local Hawaii time. Goes all over the islands, out to more than 200 miles. Lots of S9+ signals. For a very low antenna, tell me how well you get out for DX?”

NVIS is Near Vertical Incidence Skywave propagation. See https://www.qsl.net/wb5ude/nvis/ .

K9SQG wrote on September 28: “Interestingly, I’ve been having nightly schedules on 40 meters between Dayton, Ohio and Wimberley Texas, a distance of about 1500 miles perhaps, and signals both ways are +20-30 over S9 for an hour or more at a time. This is in the 9:30 to 11 pm range, Eastern time. I’m going to try earlier in the evening too and see about that.”

 

On September 28, Bil Paul, KD6JUI, wrote: “Here’s your kayak guy, Tad. I was operating today from the boat on 17 and 20-meter CW. I was using a poor wire antenna but managed two contacts on 17 meters.

However, I was amazed to hear France (F6HKA) and Italy (I8QJU) coming in loud and clear on 20-meter CW. I was unable to get any contacts on 20 meters but was surprised to hear these guys coming in like locals at around 1 pm Pacific time.”

 

The November 2016 issue of QST features an article by KD6JUI describing his kayak operations. http://www.arrl.org/news/kd6jui-wins-november-qst-cover-plaque-award

 

Charles, KW6G, wrote: “The equinox effects are definitely significant. Wednesday night, September 26, I worked an all-time new one for me: ZD9CW on Tristan de Cunha Island. He was on 40 meters around 0700 UTC and I got him on CW on the third call! I was running my Icom IC-7600 transceiver driving an Avon 1010 amplifier to a ground-mounted Butternut HF9V vertical antenna. I have copied him last night as well.

“Longer propagation does have its advantages. However, after working 277 DXCC entities, finding new ones during this time of the solar cycle is pretty difficult.”

 

Regarding comments by NN4X last week about noctilucent clouds and e-skip, Jon Jones, N0JK, mentioned that he discussed this subject in the most recent World Above 50 MHz column in QST.

AMSAT-DL Symposium Hears Update on Es’hail-2 Satellite – SpaceX

Thu, 10/04/2018 - 8:34pm
Es’hail-2 – Amateur Radio satellite – SpaceX

Progress toward the launch of the Es’Hail-2 geostationary Amateur Radio satellite was reported as AMSAT-DL held its annual symposium on September 29 at the Institute for Environment and Future Research (IUZ) Bochum Observatory in Germany. Es’hail-2 is set to go into space this fall or early winter aboard a SpaceX vehicle; a specific launch date is not available. AMSAT-DL President Peter Gülzow, DB2OS, and Achim Vollhardt, DH2VA, reported that AMSAT-DL recently finalized the individual components for the Es’hail-2 ground station in Doha, Qatar.

“Last week, we finished the work and made the equipment ready to ship,” Gülzow said. The components are to be installed in Qatar in the near future. A second facility at the Qatar Amateur Radio Society (QARS) in Doha will serve as a backup, while a third ground station will be installed at Bochum Observatory.

Es’Hail-2 will offer two AMSAT-DL-designed Phase 4 Amateur Radio transponders operating in the 2.4 GHz and 10.450 GHz bands. A 250 kHz bandwidth linear transponder is intended for conventional analog operation, while an 8 MHz bandwidth transponder will provide experimental digital modulation schemes and DVB digital amateur television (DATV). Both transponders will be equipped with antennas capable of providing full coverage of about one-third of Earth’s surface. 

amzn_assoc_placement = "adunit0"; amzn_assoc_enable_interest_ads = "true"; amzn_assoc_tracking_id = "qn0c-20"; amzn_assoc_ad_mode = "auto"; amzn_assoc_ad_type = "smart"; amzn_assoc_marketplace = "amazon"; amzn_assoc_region = "US"; amzn_assoc_linkid = "4969cf2edaec6bf602678d298f572f59";

“We hope to be able to present live broadcasts in DATV at the next HAM RADIO [in Friedrichshafen], June 21 – 23,” Gülzow said.

AMSAT-DL has been offering technical assistance on the Es’Hail-2 project. The commercial Qatari satellite will provide the first Amateur Radio geostationary communication and will be capable of linking amateurs from Brazil to Thailand.

Gülzow will deliver a presentation, “Es’hail-2 and its Amateur Radio Payload” at the AMSAT-UK International Space Colloquium, October 13 – 14, as part of the Radio Society of Great Britain Convention in Milton Keynes, England.

Colloquium presentations will be live-streamed starting October 13 at 0830 UTC. Recordings of all presentations will be posted on the AMSAT-UK YouTube channelfollowing the event.

APRS, Baofeng , and Buying Used – Ham Radio Q&A

 FCC Enforcement Advisory – Baofeng Update APRS Digipeaters and Wide1-1 path: 01:03 Buying Used Ham Radio Gear: 05:04 Update to the Illegal Baofeng Radio Saga: 08:31

 

Links referenced: FCC Enforcement Advisory DA-18-980A1:

 

From: ARRL

ARRL has taken a minor exception to the wording of a September 24 FCC Enforcement Advisory pertaining to the importation, marketing and sale of VHF and UHF transceivers and is in discussion with FCC personnel to resolve the matter. The Enforcement Advisory was in response to the importation into the US of certain radio products that are not FCC certified for use in any radio service, but identified as Amateur Radio equipment.

“While much of this equipment is actually usable on Amateur bands, the radios are also capable of operation on non-amateur frequencies allocated to radio services that require the use of equipment that has been FCC-certified,” ARRL said. “Such equipment is being marketed principally to the general public via mass e-marketers and not to Amateur Radio licensees.”

ARRL said the upshot is that the general public has been purchasing these radios in large quantities, and they are being used on the air by unlicensed individuals. “

“Radio amateurs have complained of increased, unlicensed use of amateur allocations by people who are clearly unlicensed and unfamiliar with Amateur radio operating protocols,” ARRL said. But while it supports the general tenor and intent of the Enforcement Advisory, ARRL said it disagrees with the FCC on one point.

amzn_assoc_placement = "adunit0"; amzn_assoc_enable_interest_ads = "true"; amzn_assoc_tracking_id = "qn0c-20"; amzn_assoc_ad_mode = "auto"; amzn_assoc_ad_type = "smart"; amzn_assoc_marketplace = "amazon"; amzn_assoc_region = "US"; amzn_assoc_linkid = "4969cf2edaec6bf602678d298f572f59";

“In several places, the Enforcement Advisory makes the point that ‘anyone importing, advertising or selling such noncompliant devices should stop immediately, and anyone owning such devices should not use them,’” ARRL pointed out. “The Advisory broadly prohibits the ‘use’ of such radios, but our view is that there is no such prohibition relative to licensed Amateur Radio use — entirely within amateur allocations — of a radio that may be capable of operation in non-amateur spectrum, as long as it is not actually used to transmit in non-amateur spectrum.

ARRL has had extensive discussions about this issue with FCC Wireless Bureau and Enforcement Bureau staff, and those discussions are ongoing.

“It is important to protect the flexibility of the Amateur Service as essentially an experimental radio service, but it is also very important to stop the unlawful importation and marketing of illegal radios in the United States and the use of those radios by unlicensed persons,” ARRL maintained. “We will keep our members informed as our discussions with FCC on this subject continue.”

IARU Region 1 Volunteers and Partners Getting Behind WRC-19 50 MHz

Thu, 10/04/2018 - 2:53pm
IARU Region 1 – Spectrum

International Amateur Radio Union (IARU) volunteers are continuing their work toward a favorable outcome for World Radio Conference 2019 (WRC-19) Agenda Item 1.1, which seeks a 6-meter allocation for the Amateur Radio Service in Region 1 in the International Telecommunication Union (ITU) Radio Regulations Table of Frequency Allocations. The effort is aimed at aligning the band with the 50 MHz allocations in ITU Regions 2 and 3. In a news release, IARU Region 1 (IARU R1) President Don Beattie, G3BJ, described extensive work in various forums and the ITU aimed at gaining support for a 6-meter band in Region 1, rather than the current country-by-country allocations.

“IARU has represented the global voice of Amateur Radio in these meetings, arguing that new applications in Amateur Radio require significant bandwidth at 50 MHz and has set out a proposed utilization of the band which supports its claim,” Beattie said. He added that the IARU has also engaged in extensive work on sharing studies using propagation models recognized by the ITU and the European Conference of Postal and Telecommunications Administrations (CEPT).

“The Amateur Service has met strong opposition from a few nation states who argue that the 50 MHz band is already allocated to other services in their countries — following the closure of many broadcasting stations in recent years which operated in this band — and believe that sharing the band presents problems,” Beattie said.

CEPT Project Team D has prepared two Agenda 1.1 options. The majority of CEPT administrations actively participating in discussions preferred one proposal for a 2 MHz secondary allocation. The second option, the result of a major compromise and preferred by IARU and the European Radio Amateurs’ Organization (EURAO), would see a 500 kHz primary allocation of 50.0 – 50.5 MHz, paired with a secondary allocation of 50.5 – 52.0 MHz. Beattie said either option would be an improvement over the status quo.

Additional meetings lie ahead, including a CEPT Conference Preparatory Group (CPG) meeting in November, and the ITU Conference Preparatory Meeting (CPM) in February.

“It is hoped that the cooperation between IARU and EURAO will continue in future CEPT activities, which are relevant to Amateur Radio,” Beattie said.
