First AO-85 Contact

While I’ve copied the DUV (Data Under Voice) Telemetry (a bit of challenge on an IC-9100 due to low-frequency roll-off of the internal soundcard — necessitating the use of an external soundcard to the 9600 baud interface), I’ve never made an actual AO-85 contact, so planned to give it a shot tonight.

The first pass was far to the East, and was not be very active due to that.  I heard some weak voices starting at 21:43 UTC (about 14 degrees above my horizon).

Weak signals notwithstanding, I made had a QSO with John, K8YSE in Ohio (EN91) from 21:46:23 to 21:49:19, my first for AO-85.  Thanks for your patience, John.

AO85 539PM

A more promising pass at 23:20 UTC, to my west, was actually not much better and no contacts were made.

ARISS Contact Wild Success!

For tiny Rhode Island, the International Space Station contact with students from All Saints Academy (Middletown, RI) and other schools on May 6 was BIG news.  Perhaps because it was good news, or maybe because of a statewide heightened interest in education, it appeared on all three major TV network stations (ABC6, CBS12, NBC10) during their various news programs between 5:00 PM and 7:30 PM Friday.  Newspapers, like The Newport Daily News shown below, carried it on their front page the next day.

When I came home after the event around 5 PM, I spent the next 4 and a half hours responding to emails that had come in discussing the event — it really seemed to grab people’s attention.  Friends, ham radio acquaintances, and others that somehow knew I was involved reached out to tell me how touched they were.

A common theme appeared in many of the messages, and especially in an audio capture from a local AM radio station that carried the audio feed — “There wasn’t a dry eye to be found in the studio”.  While the students at the event were star-eyed and filled with excitement over what they had just accomplished, the adults in the room, all of them, were drying their eyes.  Somehow, this connected with everyone’s heart, combining the joy of discovery, exploration, and a sense of communal accomplishment.  The adults knew this was rare air indeed and it was impossible to hold the emotional impact in check.

Personally, I had shed my tears earlier during practice sessions, when the kids were first running through their questions.  I couldn’t believe how lucky I was to be part of this.  I welled up again when I saw what I think is an incredibly touching commercial made by MTN, a continent-wide telecommunication company in Africa called “Sam from earth calling the space station”.  There is a scene, when young Sam finally reaches the Space Station, where his mother drops a plate of dishes onto the floor.

That mother’s reaction and feelings — unbelief, shock, wonderment — were felt all throughout the live event room after Paula (one of the most poised students I have ever met) called for NA1SS SEVEN times before Astronaut Jeff Williams’ voice finally broke through the noise.  Man, that was stressful, but produced a bonafide hollywood moment.

Once contact was made (1 min 50 sec after the ISS was above our horizon), the students and Jeff Williams handled the Q&A like seasoned pros — all 24 questions (an extraordinary number, I’ve been told), were asked and answered.  Paula was sending her 73, just as the ISS was fading into the noise.

The Q&A livestream can be found here:  https://www.youtube.com/watch?v=oTkq5btNW_U&feature=youtu.be

I’m still trying to get a handle on my feelings two days later so I can capture them.  How lucky was I to be a part of this.  How fortunate we were to have Mike and Beth Cullen drive this forward.  How wonderful to work with such a diverse group of people to plan this for over a year and be able to carry it out (especially the staff of All Saints Academy, who welcomed us with open arms).  How amazing that ARISS and NASA allow this to happen.

How much I envy the young school students and what awaits them.

ARISS Contact to be Friday May 6

The ARISS and NASA organizations have just announced that the All Saints Academy contact with the International Space Station will take place on Friday May 6th.

Our orbit will be a descending one, beginning at approximately 12:44 PM local time and continuing until approximately 12:54 PM.  It will rise above the horizon to our northwest, pass to our southwest, then set to our southeast, reaching a maximum elevation of 56 degrees.

More details can be found here:  http://w1sye.org/?p=2460

Packet QSO with VA3NNA via ISS (RS0ISS)

Adrian, VA3NNA, and I used UNPROTO packets to have a QSO today via the Packet Robot, RS0ISS, aboard the International Space Station.

When operating this way, the ISS acts as a digital satellite, repeating those packets that it hears back to earth.  Packets heading to the ISS are sent UNPROTO to “CQ via ARISS”. Packets returning to earth are sent to “CQ via RS0ISS*”

One of Adrian’s packets was copied and repeated via WA8LMF-SG onto the APRS network:

ARISS Practice Going Well

As of yesterday, the RF Team from NCRC has had 3 ARISS practice sessions, where we use the Packet Robot RS0ISS to check out the RF uplink/downlink and antenna tracking gear.

Usually at home I use M2 Eggbeater antennas, and that’s enough to glean a few satellite contacts a year.  When I am at Field Day, I’ll use an Arrow crossed yagi, which has been enough to get the satellite bonus the past three years.  But I am absolutely amazed to see how well a steerable antenna array works using the 2mCP14 and 436CP30 antennas with SSB Electronics Preamps.  Almost horizon to horizon coverage (at ASA, we are to the horizon to our west and south, and down to about 5 degrees on the East and North).

Today, back at home, just making sure the PC and IC-9100 are playing nice, I was only able to get a single packet reported through the APRS system:

QSL for RS0ISS Packet Arrives

I received a QSL via the ARRL for the packet activity through the ISS Packet Robot, RS0ISS on April 4th.

ISS SSTV Reception

Always looking for a new way to practice for our upcoming ARISS contact the first week of May, I setup the MMSSTV program to decode the SSTV signal being sent from ISS on 145.800 MHz.  The signal is sent using the normal FM Voice gear, so I would have expected it to not experience any “drift” but some can been seen in the image below.  The 20:43 to 20:53 UTC pass was a low altitude one, about 24 degrees, passing from west to north east of me.  The image started about 3 min after rise and ended about 3 minutes before set.

Captured April 13 2016 2046-2049 UTC

Captured April 13 2016 2046-2050 UTC

Gear was an IC-9100 with SatPCISS running Doppler adjustment.  The antenna is an M2 EB-144 Eggbeater, SSB Electronics SP-2000 preamp, and 125 feet of Belden 9913 coax — outdoor stuff circa 1998.  Signal levels without the preamp were running S5 while decoding.  Image was captured using MMSSTV.

Just Another Number

Recognizing that there isn’t anything special about this, but I noticed that I had exactly 4,000 confirmed QSOs in LotW today (63% confirmation rate).

Successful Digipeat from ISS

As our ARISS contact is 30 days away, so it is time for lots of practice.  While not at All Saints yet, I am using my IC-9100 with egg-beaters to monitor the ISS Packet Robot on 145.825 +/- Doppler.  Packets are handled by a SCS P4dragon DR-7400 modem.  This is pretty much the equal of our backsup station for the ARISS contacts.

I had a fairly decent 30 degree pass from the SSW to the NE, much lower than we will be using on the actual contact day.  I was able to copy dozens of packets from RS0ISS, the ISS packet robot, and I was able to copy several of mine go through the robot and come back down.  My packets were copied from the robot at:

  • 22:13:32  (actual UTC time is 1 min later so 22:14:32)
  • 22:14:51
  • 22:15:23
  • 22:15:51
  • 22:16:09
  • 22:16:21
  • 22:16:37
  • 22:17:00

The pass was from 22:09:36 to 22:20:08 UTC, with a 30 degree max.  Packets started decoding at 22:14:20 (almost 5 minutes into the pass) and continued to decode until  22:18:00.  I have some shadowing due to my house from the SW.

Here is a screen cap that shows the return packet from the Robot (add 1 minute to the time stamp as the DR-7400 TNC clock is exactly 1 minute slow — my outbound packet is shown immediately before the repeated one):WB4SON Digi via ISS

DXCC Update

After ironing out some system glitches, the nice folks at the ARRL checked in my paper QSLs and I found myself standing at 251 confirmed countries with 1,188 band-points.  Also, one of the paper QSLs finished 30-meter WAS, making that the 7th completed band (I lack WV for 12-meter WAS).

When I went to snag a copy of the DXCC standings, I couldn’t help but notice that it was now at 252 — confirmations from TX7EU were now in LotW system.  3 more to go for the year-end goal of 255.
