08/29/2017 The cross-band FM voice repeater aboard the International Space Station has not officially been activated for general amateur use, although some stations have reported successful contacts. The system is being used in an effort to detect telemetry from three recently deployed CubeSats. Russian ISS crew members last week released three satellites carrying Amateur Radio payloads — TOMSK TPU-120 (RS04S), with FM voice announcements on 437.025 MHz; Tanusha-SWSU-1 (RS-6S) with FM voice announcements and AX.25 9,600 bps packet on 437.050 MHz, and Tanusha-SWSU-2 (RS-7S) with FM voice announcements and on AX.25 9,600 bps packet on 437.050 MHz. They set up […]

ARISS Cross-Band Repeater Not Available for General Communication


07/26/2017 ARRL’s new 222 MHz and Up Distance Contest will debut on August 5 at 1800 UTC and continue until the next day. This 24-hour contest offers a wide range of entry categories, from FM, CW, and SSB to digital modes. The object is to work as many stations as possible on the 222 MHz through 241 GHz bands, using any allowable mode. A station in a specific grid locator may be contacted from the same location only once on each band, regardless of mode. Contacts on higher frequencies earn more points, so expect plenty of activity from locations that […]

07/11/2017 The five CubeSats making up the BIRDS-1 (Joint Global Multi-Nation Birds) constellation were deployed into orbit from the International Space Station (ISS) on July 7. Each carries an Amateur Radio payload but no transponders. The Japan Aerospace Exploration Agency (JAXA) module’s remote manipulator arm was used to accomplish the launches. “Another great example of international cooperation today on @Space_Station — launched 5 micro-satellites from 5 countries off the JAXA arm!” tweeted ISS crew member Jack Fischer K2FSH (@Astro2fish). The BIRDS-1 constellation of five 1U CubeSats — BIRD-B, BIRD-J, BIRD-G, BIRD-M, and BIRD-N — are all of the same design, […]

07/10/2017 The Amateur Radio on the International Space Station (ARISS) program is planning a slow-scan television (SSTV) event starting on Thursday, July 20, and continuing for 2 days, to commemorate its 20th anniversary. Transmissions, set to get under way around 2125 UTC, will feature 12 images from past and present ARISS activities. The SSTV signal should be available nearly anywhere on the globe at some point during the event. “Starting with our first meeting in November 1996, our joint operations on Mir, becoming the first operational payload on ISS in November 2000, to our [more than 1,100] school contact (so […]

ARISS to Celebrate 20th Anniversary with SSTV Event


07/06/2017 A recent flurry of FCC Enforcement Bureau correspondence to alleged unlicensed broadcasters has targeted at least one more radio amateur — this time in the Greater New York City area. It’s not the first time Winston A. Tulloch, KC2ALN, of Paterson, New Jersey, has heard from the FCC, which has had Tulloch in its sights for at least several months regarding a pirate FM station on 90.9 MHz. Last November, the Enforcement Bureau sent Tulloch a Notice of Unlicensed Operation after receiving information that he was operating a radio station. FCC agents used direction-finding techniques to zero in on […]

02/07/2017 In an apparent nod to radio amateurs who may have tuned in, Radio Australia’s VL8A transmitter in Alice Springs signed off on January 31 in CW. The station sent “73 de VL8A QRT,” before pulling the big switch. Radio Australia announced last fall that it planned to cease its shortwave transmissions this year. The broadcaster shut down its Katherine, Tennant Creek and Roe Creek (Alice Springs) transmitters at the end of January, but it said it would continue to broadcast on FM and AM bands, via satellite, and online streaming and mobile applications. The move has not been popular […]

Listening around the radio spectrum nowadays especially the V.H.F. and U.H.F. bands there is a huge amount of digital signals which the radio listener is unable resolve because of the lack of suitable Digital receiving equipment, available on today’s market place. You now have a solution to that great problem with the introduction of the ground breaking A.O.R.D-V-1 scanning receiver, the first integrated digital voice receiver which allows monitoring of all the popular digital voice modes, including D-star and D.M.R. You now do not need to use a pc and decoding programmes, the A.O.R. has solved that problem, although the […]

John Brier KG4AKV has released a video of his SO-50 satellite activation of Bodie Island Lighthouse for National Parks On The Air #NPOTA Bodie Island Lighthouse (pronounced “body”) is on the Cape Hatteras National Seashore which is the actual national park (not the lighthouse, which is just in it). The park is on the Outer Banks barrier islands of North Carolina. There are several lighthouses on the Outer Banks and all of them are beautiful.
