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.

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

From the next pass (23:45:55 to 23:56:39), as reported by ARISS.NET:

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.

A Grand Day at ARRL HQ

A friend of mine, Paul, N1PSX, and I drove to ARRL HQ yesterday for a visit.  It was Paul’s first trip, and the first time in a long time for me (my father and I visited in 1982 when we took our Extra exams).

Jon, KC1ECT was our tour guide and it took us about 3 hours to visit many departments and see the W1AW station.  I had a chance to chat with Debra Johnson, the Education Services Manager, about our outreach activities in RI.  And very nice folks helped Paul and me check in QSL cards for DXCC and WAS (A special Thank You to Sharon and Gloria).

There were lots of historical items on display and wonderful stories about gear that was designed for publication purposes (Tuna Can II).  There were several HW-16s stashed in various offices, lots of other Heathkit gear and Collins gear, but something that caught my attention was a Central Electronics 20A — my first SSB radio transmitter.

A surprisingly emotional experience was seeing my father’s memorial brick in the Diamond Terrace (one of several I’ve had placed over the years).  I had only seen it in my mind’s eye before.  Seeing it in the terrace brought back a flood of memories about weekly QSOs and I could hear his voice again — He’s been gone so long and I miss him so.

Everyone at ARRL HQ was extremely outgoing and helpful.  What a great group of people working on our behalf — making radio fun for us day in and day out.  Paul and I are planning to return for a full day of W1AW operation.

VK0EK Heard Island Success on 80-meters

Propagation and fate smiled on me.  Shortly after I could hear VK0EK’s 80 meter signal at about S-3 (local noise level S-2), I was able to work them a few minutes before local sunset.  Grey line propagation with a bit of a boost due to the coastal cold front perhaps. My hats off to the guys on Heard Island — they are working the magic on their end.

ISS-Above on 7″ LCD

I finally had a chance to tie the Raspberry Pi Foundation 7″ LCD/Touchscreen onto a RPi 2 running the ISS-Above firmware.  The results were outstanding.  It makes for a nice desk piece, with only a single power supply wire exiting the back (when using WiFi).  All the screens that would show up on the HDMI display, show up on the LCD instead and they look quite nice.

ISS-Above: Coolest Tool for ISS Pass Prediction – EVER

While looking for interesting things to display concerning the ISS during our upcoming ARISS contact, I stumbled across a now commercial product that started not long ago as an overfunded Kickstarter campaign. ISS-Above.

ISS-Above is a Raspberry Pi based product with different output configurations that indicate when the next International Space Station pass will happen.  The output can be attractive screens showing via a HDMI connector, various LCD modules, or simply colored blinking lights.  HDMI users have an additional feature — live streaming video feed from the Space Station (the HDEV: High Definition Earth-Viewing experiment).

While complete units can be purchased for about $150, RPi enthusiasts can use their own hardware by purchasing a SD Card image for $30.

I did the latter yesterday at about 2 PM, stuffed the SD card into a RPi Model B+ that I had hanging around with an Adafruit 16×2 LCD, and DLINK USB WiFi Dongle.  By 2:30 PM I was up and running (most of that time was spent copying the OS image to the SD card).

I am completely blown away by what Liam has done with ISS-Above.  My daughter and I sat transfixed in front of the TV watching the live video stream until the ISS went into darkness.  I’ll be buying another license and putting together more hardware for use at All Saints Academy during on ARISS Contact Day in May
