Arizona Homeowners Association and Hams Agree on Outdoor Antenna Guidelines

QRZ Now - Wed, 05/15/2019 - 6:37am

The Board of Directors of an antenna-restricted community in Arizona voted overwhelmingly in April to allow radio amateurs to erect certain outdoor antennas on their properties. Some 75 hams live in the 10,000-home Sun City Grand, a self-contained residential community for older adults. An article in the Grand Ham Newsletter by Gordon Bousman, NW7D, called it “a big win” and said the Sun City Grand community homeowners’ association (HOA) is believed to be the largest in the US to permit Amateur Radio antennas. The HOA board includes one radio amateur. The new antenna guidelines went into effect on May 9.

“The road to success took nearly a year of meetings, negotiations, and occasional setbacks driven by a team of dedicated amateurs who were persistent in reaching our goals,” Bousman said in his article. “While our initial discussion points focused on the possibility of passage of the [Amateur Radio] Parity Act, we later shifted our focus to the value that Amateur Radio operators can bring to the community in the event of an emergency or crisis.”

Bousman told ARRL the group “somewhat” modeled its antenna proposal after that of the Sun City Texas Ham Radio group in Georgetown, Texas, which permitted several years ago. “In our research, we learned that Sun City Hilton Head, South Carolina, and Sun City Henderson, Nevada, also allow certain Amateur Radio antennas,” he added. “There may be other communities with similar antenna permissions, but we did not uncover any in our research.”

The types of antennas permitted are modest. The list includes flagpole antennas that do not exceed 16 feet, verticals that do not rise more than 5 feet above the peak of a home, and wire antennas no higher than 5 feet above the roof peak. No traps in wire antennas are allowed and towers of any type remain prohibited.

“[These] antennas should provide amateurs very adequate capabilities to work long distances on the HF bands and to be able to adequately communicate across our community on the VHF/UHF bands — as well as being able to reach most repeaters in the Phoenix area valley including several emergency repeaters,” the newsletter article opined.

Radio amateurs will need to apply to the HOA’s Architectural Review Committee Standards Office to obtain approval and may only erect two outdoor antennas.

Bousman said more than a dozen antenna applications were submitted in the first week and other hams are working on designs. “We have encouraged all of our ham club members to get VHF/UHF antennas installed as soon as possible so that we can begin our [emergency communication] exercises,” he told ARRL.

The newsletter included technical information on various antenna configurations and resources on where to obtain commercial antennas that would meet the HOA requirements. As suggested reading, the newsletter recommended four ARRL antenna books, including The ARRL Antenna Book and Antennas for Small Spaces.

This year’s second Kidsday will be held on Saturday 15th of June. This event is especially created to promote Amateur Radio to youth. This is a moment where you can share your amateur radio hobby with your family, grandkids, friends, scouts or even to the general public. This day can be the first time for youth to experience a real radio QSO, hopefully they get interested in becoming a licensed amateur radio operator.

You could make use of this suggested exchange: Name, age, location and favourite colour. Be sure to work the same station again if an operator has changed. To draw attention, call “CQ Kids Day.”

ARRL Invites Applications for Volunteer Monitor Positions

QRZ Now - Tue, 05/14/2019 - 10:42am

ARRL is now accepting applications from individuals interested in becoming part of the new Volunteer Monitor program, a joint undertaking of ARRL and the FCC. The program seeks volunteers who — working under the direction of ARRL — will monitor and survey the Amateur Radio bands both to detect improper activity and to recognize exemplary on-the-air behavior.

Prospective Volunteer Monitors must be ARRL members. They will undergo a training and certification program administered by ARRL, and will be vetted by ARRL through at least one oral interview and a preliminary evaluation by ARRL staff. Such requirements will continue for Volunteer Monitors once they are selected.

Volunteer Monitors will serve 3-year terms at the pleasure of ARRL, and ARRL will reserve the right to terminate the participation of any Volunteer Monitor for any reason.

Volunteer Monitors must be able to utilize state-of-the-art receiving equipment and to access no-cost remote receive sites, if requested. Applicants must possess strong writing and communication skills and an understanding of the importance of thorough documentation. They must have basic word processing and data entry skills and be able to send such information, including recordings, to ARRL electronically.

Applicants must have no history of warning letters or other enforcement-related action from the FCC, must hold a Technician or higher license class, and must have been licensed for at least 3 years.

Applicants should send a copy their applications to their Section Manager (see page 16 in any recent issue of QST for a complete list of Section Managers and their contact information). 

In February, Riley Hollingsworth, K4ZDH, was named to oversee the development and implementation phases of the Volunteer Monitor program, which will replace the Official Observers (OO) program. Hollingsworth once handled Amateur Radio enforcement for the FCC.

A strong (G3) geomagnetic storm is currently in progress

QRZ Now - Tue, 05/14/2019 - 7:42am

Surprise! A strong (G3) geomagnetic storm is currently in progress thanks to an enhanced solar wind stream containing a sharply south pointing Bz. Visible aurora is likely at middle to high latitudes if it is still dark outside.

ALERT: Geomagnetic K-index of 7
Threshold Reached: 2019 May 14 0859 UTC
Synoptic Period: 0600-0900 UTC
Active Warning: Yes
NOAA Scale: G3 – Strong
Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude.
Induced Currents – Power system voltage irregularities possible, false alarms may be triggered on some protection devices.
Spacecraft – Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur.
Navigation – Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur.
Radio – HF (high frequency) radio may be intermittent.
Aurora – Aurora may be seen as low as Pennsylvania to Iowa to Oregon.

Arizona Homeowners Association and Hams Agree on Outdoor Antenna Guidelines

ARRL News - Mon, 05/13/2019 - 7:59pm

The Board of Directors of an antenna-restricted community in Arizona voted overwhelmingly in April to allow radio amateurs to erect certain outdoor antennas on their properties. Some 75 hams live in the 10,000-home Sun City Grand, a self-contained residential community for older adults. An article in the Grand Ham Newsletter by Gordon Bousman, NW7D, called it “a big win” and said the Sun City G...

IC-9700 Review and Smackdown vs the IC-910H

QRZ Now - Mon, 05/13/2019 - 3:17pm

George and Tommy from AmateurLogic review the IC-9100 with Ray Novak, N9JA from Icom. In this classic smackdown episode, the IC-9700 goes up against the IC-910H. For more information on the IC-9700, please visit: https://www.icomamerica.com/9700

Direct Sampling Brought to the VHF/UHF World

Built with the VHF/UHF weak signal operator in mind, the IC-9700 is an RF direct sampling receiver for 2m and 70cm. The IF receiver consists of a single, down conversion for 23cm that is between 311 – 371MHz. This design provides a quiet receiver due to Icom’s DSP technology. The robust PA provides 100W on 2m, 75W on 70cm, and 10W on 23cm.

Band Management

In addition to band specific memory channels, the IC-9700 allows band specific receiver and transmitter settings. For transmit, users can make adjustments to RF power, TX power Limit, Limit Power, and TX Delay by band. Basic receiver settings, like the Noise Blanker, Noise Reduction, and others can be tweaked by band with a dynamic Notch and Filter setup by band/mode.

Other Planned Features Include:
  • All mode, tri-band transceiver covering 144, 430/440 as well as 1200MHz
  • Supports CW/AM/SSB/SM/RTTY and D-STAR DV and DD modes

  • Real-time, high-speed spectrum scope & waterfall display
  • Dualwatch operation and full-duplex operation in the satellite mode
  • Supports 2 wave simultaneous reception (different band / different mode), full duplex operation.
  • D-STAR Terminal and Access Point mode (RS-MS3A/W)
  • Dual D-STAR receive (decodes two voice streams simultaneously)
  • Full duplex operation/Dual Watch (no V/V or U/U Capability)
  • Main or Sub-Band Scope (Center/Fix mode +/-500kHz Center Mode)
  • Audio Scope
  • CW full break-n
  • 0.5ppm frequency < +/- 0.5ppm (–10°C to +60°C; 14°F to 140°F)
  • Voice Recording/playback function (SD Memory Card)
  • Ethernet Port (Internal RS-BA1 Server)
  • USB audio and control connection
  • DR Memories: 2,500

Yaesu FTM-400DR [ Review ]

QRZ Now - Mon, 05/13/2019 - 8:21am

FTM-400XDR C4FM FDMA / FM 144/430 MHz DUAL BAND TRANSCEIVER

The new FTM-400XDR includes an improved GPS receiver that employs the latest in GPS technology providing faster and more accurate satellite searching functionality. These advancements will reduce GPS Time-to-First- Fix (TTF) thereby speeding up navigation and telemetry functions. The FTM-400XDR replaces the previous model, the FTM-400DR.

The FTM-400XDR is the first mobile introduced to be a fully compatable radio partner for use on the YAESU System Fusion Dual Mode system. Compared to other digital modulation schemes within FDMA, C4FM has excellent communication quality (BER: Bit Error Rate characteristics). C4FM is the standard method for professional communication devices in FDMA, and is therefore considered to be the main stream digital communication mode in the future.  Download our “Digital Communications Guide for Amateur Radio Operators” available on our web site that explains more about this efficient and reliable digital mode.

The FTM-400XDR operates in three (3) Digital modes and an (1) Analog mode to suit your needs. This feature packed radio is our first Digital Mobile equipped with our new Automatic Mode Select (AMS) function that instantly detects the received signal mode. The AMS function enables stress-free operation and eliminates the need to manually switch between communication modes.   V/D Mode   (Voice/Data simultaneous communication mode) The digital voice signal is transmitted in one half of the band width. Simultaneously the other half of the 12.5 kHz band width channel is used for error correction of the voice signal and other data. By incorporating powerful error correction technology developed for professional communication devices, effective error correction codes provide the advantage of fewer interruptions to conversations. The Clear Voice technology developed for the C4FM FDMA Digital mode provides the ideal balance of error correction and sound quality.   Voice FR mode   (Voice Full Rate Mode) This mode uses the full 12.5 kHz bandwidth to transmit digital voice data. The increased amount of voice data permits high quality voice communication, providing superb sound quality for a “rag chew” with friends.   Data FR mode   (High Speed Data Communication Mode) This high-speed data communication mode uses the full 12.5 kHz bandwidth for data communication. The transceiver automatically switches to Data FR mode when transmitting snapshot pictures, and can be used to transmit large quantities of data at high speed. Analog FM mode Analog FM is effective when weak signal strength causes audio drop out in the digital mode, and enables communication up to the borderline of the noise level. Also the use of established Yaesu low power circuit designs provides greater efficiency than the digital modes.  This is the typical FM mode used by most typical non-digital handhelds and VHF/UHF mobiles.

Dayton Hamvention 2019 – PRESS RELEASE

QRZ Now - Sat, 05/11/2019 - 5:30pm

“Hamvention is just over a week away. Do you have your shopping list ready? How about those comfortable walking shoes? It’s time to get everything in order to attend the biggest and best amateur radio event of the year!
We at Hamvention have another exciting announcement. If you are curious about a topic and would like to get some info before you leave for the show, or you aren’t going to be able to make it and want to hear what’s going on, we have another way for you to talk to us prior to the show.


We are going to have a HF “Talk-In” net next Monday and Tuesday evenings. We will be there to answer questions and give out general information pertaining to the show. Our plan is to have two time slots of approximately 2 hours each on both nights. We will be on the air on 7.215 MHz at 1800-2000 EDT (2300-0100 GMT) and on 3.875 MHz at 2200-0000 EDT (0300-0500 GMT) each night. Our operating frequencies will be plus or minus QRM.
For those operators that work W8BI during this event, we will be sending out a special “Hamvention 2019 HF Talk-In Net” QSL card! This will be a unique card for those of you that collect them.
Take advantage of the opportunity to “get the scoop” early, get your questions answered before you head out, and stake your claim on a very limited edition QSL card. Whatever the reason, we look forward to talking to you on the air.
