Happy Birthday! Samuel F.B. Morse

QRZ Now - Sat, 04/27/2019 - 8:17am

Developed in the 1830s and 1840s by Samuel Morse (1791-1872) and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations. In addition to helping invent the telegraph, Samuel Morse developed a code (bearing his name) that assigned a set of dots and dashes to each letter of the English alphabet and allowed for the simple transmission of complex messages across telegraph lines. In 1844, Morse sent his first telegraph message, from Washington, D.C., to Baltimore, Maryland; by 1866, a telegraph line had been laid across the Atlantic Ocean from the U.S. to Europe. Although the telegraph had fallen out of widespread use by the start of the 21st century, replaced by the telephone, fax machine and Internet, it laid the groundwork for the communications revolution that led to those later innovations.

DX Engineering UCGC-Z Universal Copper Grounding Clamps

QRZ Now - Fri, 04/26/2019 - 1:18pm

DX Engineering Universal Copper Grounding Clamps DXE-UCGC-Z

DX Engineering Universal Copper Grounding Clamps are custom designed to provide a ground rod mounting solution for various types of lightning protectors commonly used for Amateur Radio. The “Z” design makes it easy to install and remove coaxial cable connectors. This ground rod clamp for surge protector mounting is ideal for permanent installations as well as for temporary installations, such as Field Day.

Additionally, a solid copper strap from the station grounding bus bar may also be sandwiched between the copper plates of this clamp and the ground rod (not shown).

ground rod clamp for surge protector mounting

The DXE-UCGC-Z can easily mount up to six lightning protectors. The photo shows two DX Engineering protectors and two PolyPhaser protectors installed on a DXE-UCGC-Z mounted to a 5/8 in. diameter ground rod. Other lightning protection products can also be mounted, such as the DXE-IS-RCT Control Line Protector and Alpha Delta Lightning Protectors.

The DXE-UCGC-Z Copper Grounding Clamp Features:

– Mounts up to six protectors onto one ground rod

– Fits common standard 5/8 in. through 3/4 in. diameter ground rods

– Made from 1/16 in. thick Copper Alloy 110 for maximum conductivity

-“Z” bends in the copper for easier installation and removal of coax connectors on protectors

– Easy to assemble two-piece construction. Each plate is approximately 3-1/4 in. wide x 4-3/16 in. tall

– Stainless Steel hardware is included: Four 1/4 in.-20 x 3/4 in. long hex head bolts, eight 1/4 in. flat washers, four 1/4 in.-20 Nyloc hex nuts

– Using this copper clamp is faster and easier than building up the joint for an exothermic weld

An anti-seize compound such as JTL-12555 Jet Lube SS-30 Pure Copper Anti-Seize must be used on the threads to prevent galling or seizing of stainless steel hardware. All connections must be generously coated with a conductive joint compound to prevent moisture penetration and enhance conductivity such as JTL-12555 Jet Lube SS-30 Pure Copper Anti-Seize. DX Engineering’s DXE-CCK Copper Cleaning Kit also contains a small amount of the proper joint compound, brush and cleaning pad to properly prepare the copper surfaces.

Prior to attaching the lightning protectors, you may want to install the proper coaxial cable lines to the protectors and weather seal the PL-259 connectors using TES-2155 Temflex Rubber Sealing Tape with an overwrap of TES-06132 3M Super 33+ Vinyl Tape or TES-06143 3M Scotch Super 88 Premium Vinyl Tape. These easily removable connector sealing tapes are now available in kits; click to see our DX Engineering Coaxial Connection Weatherproofing Kit with instructions and a video!

Also, the lightning protector bodies are not weatherproof and it is suggested to use a DX Engineering Weatherproofing Kits, to permanently cover the body of the protectors. Some users have also suggested covering the entire assembly with a plastic food container or plastic trash bin

As with all electronic equipment, take proper safety considerations. For example: Do not install if there is a storm anywhere in your area. Do not adjust or touch the grounding system equipment when there is a storm anywhere in your area. Make sure all power is removed before making any adjustments or working on any ground system or grounding components.

Low Audio for ISS SSTV Transmissions Raises Issue of Crew’s Ability to Intervene

QRZ Now - Thu, 04/25/2019 - 1:01pm

Reception problems owing to low audio levels plagued a recent round of Amateur Radio on the International Space Station-sponsored (ARISS) slow-scan TV transmissions. Some clever operators on the receiving end were able to use software to bump up the deficient audio so the images would decode properly. But the matter raised questions concerning the ISS crew’s ability to troubleshoot problems and to make adjustments to the Amateur Radio gear on the fly. ARISS-International Chair and AMSAT Vice President for Human Spaceflight Programs Frank Bauer, KA3HDO, subsequently posted an explanation of how Amateur Radio fits into the operation of the ISS and the astronauts’ ability to service and operate it.

“Please remember that ARISS is not the prime activity on ISS,” Bauer said. “There are over 300 international experiments currently operational on ISS on this expedition. I just heard in a teleconference last week that that number will go to about 500 experiments in the next 1 – 2 years.”

Bauer said the vast array of ongoing experiments means it’s only possible to “occasionally get suggestions to the crew” to make changes relative to the Amateur Radio payload. “Any workarounds on any experiment/payload will compete with the crew’s already fully booked schedule,” Bauer explained. “Several ARISS team members, particularly our teammate in Russia, were out of pocket this past weekend. Our Russian colleague was informed of the [low audio] issue early on and acknowledged the issue. But he also needs to get tied into Mission Control. That is difficult from afar. And even if we ask for a change, it is challenging to get the crew time to make this happen, especially if it is outside the flight planning stage.”

Bauer said that once ARISS has its Interoperable Radio System on board, it plans to augment the system with ground-command capability. “We have already developed a concept for this capability,” Bauer explained. “Once in place, we will be able to do many things with our radio without crew intervention, including mode changes to support SSTV, APRS, voice repeater, etc. This capability will also be important if we fly ham radio on the Lunar Gateway, which will not have crew on it 24/7.”

Bauer pointed out that keeping ARISS afloat and able to implement new Amateur Radio capabilities requires “a great deal of funding.”

“As an example, ARISS currently has two individuals on travel to NASA Johnson running tests for the Interoperable Radio System,” he said. “This is one of three trips required to get the radio system ready for flight. Each will cost ARISS about $3,000 in travel — nearly $10,000 for these three testing events. Also, this past week, we spent $1,100 to transport the HamTV that was returned from ISS back to Italy to undergo troubleshooting to potentially repair the anomaly we experienced on ISS.”

Bauer used the opportunity to note that ARISS has a fundraising activity under way to get the Interoperable Radio System ready for launch. “We need $150,000 by the end of this year and are well short of our goal right now,” he pointed out. “If you really want to see improvements in the ISS radio system from where it is today, please strongly consider donating to ARISS. At some donation levels, your call sign and name will be included on the interoperable radio system that will fly to ISS!” — Thanks to AMSAT News Service

Low Audio for ISS SSTV Transmissions Raises Issue of Crew’s Ability to Intervene

Some clever operators on the receiving end were able to use software to bump up the deficient audio so the images would decode properly. But the matter raised questions concerning the ISS crew’s ability to troubleshoot problems and...

See More about New FT4 Here

(adsbygoogle = window.adsbygoogle || []).push({}); “At about 20 minutes into the presentation, Joe describes FT4 as being asynchronous, meaning that you can start transmitting any time you wish, rather than being synchronized to an accurate clock.  That asynchronous method did not work out as well as expected in on-the-air testing, and was abandoned.  The version of FT4 that will be coming out on Monday is synchronous, on a 6-second cycle, and requires a more accurate clock than FT8.  One thing that you can do now, before the program release on Monday, is to make sure that your computer clock is as accurate as possible.  The Meinberg NTP program is recommended by K1JT for keeping your clock accurate https://www.meinbergglobal.com/english/sw/ntp.htm You can check the accuracy of your computer clock by going to www.time.is
