Frequency 145.800MHz
4 to 5 seconds of silent carrier approx 4 minutes into pass followed by a
shorter burst of 1 to 2 seconds.
2 seconds of silent carrier approx 9 minutes into pass.
Above timing based on Keps which I believe to be wrong.
After predicted LOS a further couple of carrier bursts were heard at approx
+ 2 minutes with a characteristic sound of an intermittent connection.

Frequency 145.800MHz
30 seconds of silent carrier at 3 minute interval.
Keps are still wrong as default download by PCsat32 & HRD. Signal audible
long after predicted LOS.

There have been rumors in the past indicating that the ISS was having
direct contacts on the 40 meter band. There is no HF radio equipment on
board
and available yet. The HF antenna is mounted. Sometimes WA3NAN will
retransmit shuttle audio.

Sadly, same again, approximately 30 seconds of silent carrier at 3 minute
intervals.
Latest Keps would appear to be wrong, a signal being received nearly 1
minute after predicted LOS on this and previous pass.

Same here during the 13.20 UTC pass.Very strong carrier 59 +20db and it was
59 even after LOS.

ISS system is keying up every 3 minutes as expected but no data transmitted,
silent carrier only. Carrier remains keyed up for 30 seconds then drops.
Signal is very strong suggesting a high power output is selected.

Amateur Radio on the International Space Station (ARISS) Status Report
August 3, 2009
1. Upcoming School Contact
An Amateur Radio on the International Space Station (ARISS) contact has been scheduled for United Space School in Seabrook, Texas on Wednesday, August 5 at 13:47 UTC via telebridge station ON4ISS. The school is a once a year session of high school students that meets annually in the NASA/Clear Lake Area. These students come from around the world for a two week session, during which they stay with local host families while being mentored by astronauts, engineers, and scientists to design a mission to Mars as their team project. Class sessions are held at the University of Houston at Clear Lake. The contact will allow students to learn firsthand what the experience of spaceflight is like. They will use this knowledge in putting together their team project presentation, which they will present to the Houston space community at the end of their session.
2. ARISS Contact with Hospital for Sick Children
On Thursday, July 30, patients of the Hospital for Sick Children in Toronto, Ontario, Canada participated in an Amateur Radio on the International Space Station (ARISS) contact. Children spoke with Astronaut Robert Thirsk, VA3CSA via telebridge station ON4ISS in Belgium and were able to ask 18 questions about life in space. Nearly 100 people were present for the event and the contact was broadcasted throughout the hospital on closed circuit television.
3. ARISS Contact Between Michael Barratt and Summer Playground Camp
Borough of New Providence, NJ, Summer Playground Camp in New Providence, New Jersey took part in an Amateur Radio on the International Space Station (ARISS) contact on Thursday, July 30. Ten children asked twenty questions of Expedition 19's Michael Barratt, KD5MIJ in front of an audience of approximately 100 people. This was a town sponsored summer camp activity for elementary school children (K - 6). The New Providence Amateur Radio Club (NPARC) has been involved with this type of camp for the last five years and regularly provides an introduction to amateur radio on the air by setting up HF and VHF stations so that campers may communicate with hams around the world. The ARISS contact was an extension of this activity.
4. ARISS News on Amateur Radio Newsline
On July 31, Amateur Radio Newsline Report 1668 reported on the Scout Space Jamboree in Rantoul, Illinois which included an Amateur Radio on the International Space Station (ARISS) contact. To view "Ham Radio in Space: Space Jam 3 in Illinois," see: ftp://ftp.arnewsline.org/quincy/News-A/news.txt
