YX0V DXpedition to Aves Island to Include Satellite Operations

The YX0V DXpedition to Aves Island, scheduled for August 31, 2016 – September 10, 2016, will include satellite operations. Aves Island, a dependency of Venezuela located west of Dominica and Guadeloupe in the Caribbean Sea (grid FK85eq), is currently the 17th most wanted DXCC entity on the Club Log DXCC Most-Wanted List and was last on the air in 2007. It was active on satellite during the YV0D expedition in 2004, but only three QSOs were made before the DXpedition was cut short due to rain.

Satellite plans are yet to be finalized. Please check back for further details. YX0V information can be found on their website at http://yx0v.com/, on Twitter at https://twitter.com/yx0v2016, and on Facebook at https://www.facebook.com/groups/yx0v2016/


Happy 20th Birthday to FO-29!

Happy 20th Birthday to Fuji-OSCAR 29! FO-29, known as JAS-2 (Japan Amateur Satellite #2) prior to launch, was built by the Japan Amateur Radio League and launched on August 17, 1996 from Tanegashima Space Center on an H-II launch vehicle into a 1,323 km x 800 km orbit with an inclination of 98.5 degrees. In addition to a 100 kHz wide analog Mode V/u (JA) transponder, the satellite also includes a packet BBS and digitalker. While the packet BBS and digitalker are non-functional, the analog transponder continues to provide excellent service to the present day.

With an apogee of 1,323 km, FO-29 provides satellite operators with excellent DX opportunities every few months when the passes over a certain area are at or near apogee. Intercontinental QSOs are regularly reported, including between Japan and Alaska as well as North America and Europe. Although the theoretical maximum range at apogee is 7,502 km, the excellent sensitivity of the transponder as well as it’s strong and solid 1 watt downlink signal allows that distance to be stretched when the conditions are suitable. The longest distance QSO made via FO-29’s analog transponder occurred on August 27, 2015 with an unscheduled 7,599.959 km contact between KG5CCI in Arkansas and F4CQA in France.

The sensitivity of the transponder and Mode V/u configuration also allow for the effective use of minimal equipment. QSOs have been reported using a single Yaesu FT-817 transceiver and the stock rubber duck antenna. Taking advantage of the large footprint and ease of use, the K1N DXpedition to Navassa Island made a total of 29 QSOs during two passes of FO-29 on February 12, 2015 using a single Yaesu FT-817 along with an Arrow antenna, activating that extremely rare DX entity on satellite for the first time since 1978. To this day, FO-29 remains the most widely used linear transponder satellite and an ideal satellite for beginners looking to become active on the linear transponder satellites to try first. The FO-29 control station maintains a blog (in Japanese) at http://blog.goo.ne.jp/fo-29. The JARL also offers an award for confirmed QSOs with ten different stations via FO-29.

ARRL NPOTA Activation of President’s Park (The White House) – August 5th & August 6th

Members of the Great South Bay ARC headed by Mike Sartoretti, KC2SYF, have obtained a permit from the National Park Service to operate from President’s Park (The White House) for the ARRL National Parks on the Air event. The operating location will be the southeast side of the Ellipse. The call sign for the operation will be KC2SYF and the park designator is DZ10.

Paul Stoetzer, N8HM, will be providing satellite operations and will be active on all voice satellites (SSB/FM) from 1400 UTC to 2100 UTC on Friday, August 5th and Saturday, August 6th. The pass list is below:

RadFxSat (Fox-1B) Nearing Completion

RadFxSat flight unit has been assembled and is going through various stages of testing before it is put through environmental (shock, vibe, bakeout) testing in August  for completion in early September.  Launch is scheduled for January 20, 2017.

In a recent test stop in Fox Labs for a few days, most of the testing was streamed live on YouTube to give enthusiasts an opportunity to “look over the shoulder” of VPE Jerry Buxton, N0JY as he conducted tests on the flight unit along with other Fox Engineering Team members on GoToMeeting.

If you missed the live video, you can view the archives at


RadFxSat is expected to be back in Fox Labs around August 11 for another round of tests and it is planned to have live streaming during those tests as well.
