Beginning October 1, ARRL will offer a 10% discount on all applications for 5Band Worked All States (5B WAS) wall plaques and Triple Play (TPA) wall plaques. The discount will be deducted from the total charge (i.e., application fee, plaque fee, and shipping).

This special is good for first-time applicants, as well as for those who have been awarded TPA or 5B WAS and want to display their achievement with an attractive, colorful wall plaque.

Submit contacts via Logbook of The World (LoTW) and indicate in the comments section of the payment page that you want the wall plaque. Discounts will be applied during processing.

Apply online with the order forms available to order plaques for the Triple Play or 5Band WAS. This offer is good until the close of business at ARRL Headquarters on December 31, 2020, so if you need some contacts to complete your 5Band WAS or Triple Play awards, the November Sweepstakes or ARRL 160- or 10-Meter contests are good opportunities to fill those empty slots on your scorecard.

Uploading your contacts to LoTW provides quick contact confirmation and makes it easy to apply for these awards.

Weekly Union County Club Net on the Marysville 2 Meter Repeater

Two well-known ham radio authors and speakers will share their expertise with members in October during ARRL Learning Network webinars.

• ARRL Contributing Editor Ward Silver, N0AX, will present “Grounding & Bonding for Home HF Stations” on Tuesday, October 6, at 10 AM PDT/1 PM EDT/0500 UTC.
• Popular ARRL author Glen Popiel, KW5GP, will present “Welcome to the World of Arduino” on Thursday, October 15, at 5 PM PDT/8 PM EDT (0000 UTC on Friday, October 16). Members must log in to the ARRL website to register for each webinar.

Silver authored the ARRL book Grounding and Bonding for the Radio Amateur in 2017 as a practical guide to building a station that incorporates effective grounding and bonding techniques for electrical safety, lightning protection, and RF management. Radio amateurs often cite the title for demystifying an often misunderstood or intimidating topic.

During his webinar, Silver will define grounding and bonding, cover the benefits and requirements, and share useful references and guides for hams to apply these techniques in their home HF stations.

In his presentation, Popiel — the author of several ARRL books, including Arduino for Ham Radio, More Arduino Projects for Ham Radio, and High Speed Multimedia for Amateur Radio — will cover the open-source, electronic-prototyping Arduino platform, which is widely popular among electronics hobbyists and radio amateurs. The webinar will include examples of how to put Arduinos to use in building ham radio projects and practical station gear.

Live question-and-answer periods will follow each 30-minute presentation.

The ARRL Learning Network webinar series was introduced as a new membership benefit in July. Presentations are by members, for members, as part of ARRL’s Lifelong Learning initiative. Topics cover three primary interest areas among radio amateurs, including electronics and technology, personal communications and operating, and emergency communications and public service.

All webinars are recorded, so members and radio clubs can view previous presentations. Join ARRL to take advantage of this new member benefit.

The post Best Handheld Ham Radio TRI BAND for 2020 – Tri Band Radio Comparison appeared first on QRZ NOW - Ham Radio News.

Hara Arena, the former venue for Dayton Hamvention® and myriad sports, entertainment, and other presentations over the years, will soon be history. In the wake of a failed attempt to revitalize the tornado-damaged complex, officials in the city of Trotwood, Ohio — where Hara Arena is actually located — announced plans last week to raze the complex and rezone the property from commercial recreation to light industrial.

“The complex suffered extensive damage during the 2019 Memorial Day tornado outbreak,” the city said in a news release on September 25, taking note of hopes to salvage the complex. “However, redeveloping the property would be a challenge due to the extent of the damage, so the decision was made, and a contract has been secured to demolish the legendary venue.”

The city said the zoning change will allow manufacturing, distribution centers, and call centers to establish their businesses in the area.

“We are excited for what the future holds for this property,” Trotwood Mayor Mary McDonald said.

The Dayton Daily News reported that the owners of the property have said the iconic marquee spelling out “Hara Arena” atop the main arena will be preserved and auctioned off at a later date, with the proceeds donated to charity.

The Hara complex and the surrounding real estate occupy some 128 acres all together.

Owner Corey Heitz told the Dayton Daily News that it will take up to 6 months to tear down the buildings completely, and he hopes to have “something” there in the next 12 months.

Hara Arena had served as the venue for Dayton Hamvention from 1964 until 2016. Hamvention announced in July 2016 that Hara Arena would be closing and that Hamvention would continue. The show is now held at the Greene County Fairgrounds and Expo Center.

Over its six-decade history, Hara Arena hosted concerts by performers that included the Rolling Stones and the Grateful Dead; it was also where hockey legend Wayne Gretzky played his first professional hockey game.

CAMSAT says the CAS-7A launch has been postponed until next May, and CAS-5A until next June.

“Because of COVID-19, many things have been delayed,” CAMSAT’s Alan Kung, BA1DU, told ARRL. He said an announcement would be made closer to the announced launches.

CAMSAT said last spring that CAS-7A would launch in mid-September; the launch has been postponed multiple times since first announced. CAS-5A was predicted to launch in October. Both satellites will carry two transponders that include HF, in a configuration similar to that of the Russian RS satellites decades ago.

CAS-7A will be placed into a sun-synchronous orbit with an inclination of 98° at 500 kilometers above Earth. The transponders will have a bandwidth of 30 kHz. According to the IARU amateur satellite frequency coordination page, the HF/HF linear transponder will uplink on 15 meters — 21.245 – 21.275 MHz, and downlink on 10 meters — 29.435 – 21.465 MHz. A CW beacon will transmit on 29.425 MHz. The HF/UHF transponder will uplink at 21.3125 –  21.3275 MHz, and downlink at 435.3575 – 435.3725 MHZ. A CW beacon for that transponder will transmit on 435.430 MHz.

The CAS-5A nanosatellite, with a 6U form factor, carries two HF transponders and two VHF/UHF transponders. While in orbit, it will deploy the tiny CAS-5B femtosatellite, w which will weigh just 0.5 kilogram.

The array of CAS-5A linear transponders will include HF/HF, HF/UHF, and VHF/UHF with 30-kHz passbands (except 15 kHz for the HF/UHF transponder).

CAS-5A will include CW telemetry beacons on HF and UHF. The HF CW beacon will be at 29.465 MHz, and a UHF telemetry beacon will be at 435.57 MHz. Other beacons include the HF/HF transponder beacon at 29.490 MHz; the HF/UHF transponder beacon at 435.505 MHz, and the VHF/UHF transponder beacon at 435.540 MHz. Telemetry will be transmitted at 435.650 MHz. The V/U linear transponder will uplink at 145.820 MHz; the V/U FM transponder will uplink at 145.925 MHz. Terrestrial stations will access the transponders at 21.385 – 21.415 MHz.

A Moscow Aviation Institute MAI-75 slow-scan television (SSTV) experiment event is planned for Wednesday, September 30, from 1305 UTC to 1845 UTC, and Thursday, October 1, from 1230 UTC to 1745 UTC. SSTV signals will be transmitted on 145.800 MHz, ± Doppler shift. The expected mode will be PD 120, and the call sign will be RS0ISS. Received images of reasonable quality may be posted on the ARISS...

The latest beta release of the WSJT-X digital software suite includes digital protocols particularly designed for communication on LF and MF bands, such as 2200 meters and 630 meters, and its developers say that during its first few months of testing, contacts have spanned intercontinental paths “many times” on those bands. New protocols FST4 and FST4W are included in WSJT-X version 2.3.0-rc1 (release candidate 1). FST4 is for two-way contacts, while FST4W is for “quasi-beacon” style WSPR transmissions. Both modes offer a range of options for T/R-sequence lengths and threshold decoding sensitivities extending well into the –40 dB range, developers said.

“On these bands, their fundamental sensitivities are better than other WSJT-X modes with the same sequence lengths, approaching the theoretical limits for their rates of information throughput,” the WSJT-X development team said in releasing version 2.3.0-rc1. The developers said, “FST4 and FST4W do not require the strict, independent time-synchronization and phase-locking of modes like EbNaut,” a protocol for VLF and LF communication.

The WSJT-X development team said operators familiar with the software suite will find using FST4 and FST4W straightforward. “Most on-screen controls, auto-sequencing, and other features behave as in other modes,” the developers said. “Operating conventions on the LF and MF bands make it useful to have additional user controls to set the active frequency range used by the decoder.”

The new modes use 4-GFSK modulation and share common software for encoding and decoding messages. FST4 offers T/R sequence lengths of 15, 30, 60, 120, 300, 900, and 1,800 seconds, while FST4W omits the lengths shorter than 120 seconds. Submode names, such as FST4-60 and FST4W-300, indicate sequence length in seconds.

Message payloads contain either 77 bits — as in FT4, FT8, and MSK144 — or 50 bits for the WSPR-like messages of FST4W. Message formats displayed to the user are like those in the other 77-bit and 50-bit modes in WSJT-X. Forward error correction uses a low-density parity check (LDPC) code with 240 information and parity bits. Transmissions consist of 160 symbols: 120 information-carrying symbols of two bits each, interspersed with five groups of eight predefined synchronization symbols.

Threshold sensitivity (SNR in a 2500 Hz bandwidth, yielding a 50% probability of decode) was measured for each sub-mode using simulations over the additive white Gaussian noise (AWGN) channel. As with other recently developed modes in WSJT-X, a feature called a priori (AP) decoding can improve sensitivity by several additional decibels as information is accumulated during a standard minimal contact or FST4W operating session.

“Keep in mind that these are very narrow-band modes; achieving the sensitivities listed in the table requires that oscillator drifts and path-induced Doppler shifts must be less than the tone spacing, over the full sequence length,” the developers said.

WSJT-X version 2.3 offers 12 different protocols: FST4, FT4, FT8, JT4, JT9, JT65, QRA64, ISCAT, MSK144, WSPR, FST4W, and Echo. The first seven are designed for making reliable contacts under weak-signal conditions and use nearly identical message structure and source encoding.

The WSJT-X 2.3 User Guide and the Release Notes include additional information.
