Bob, I presume this is similar to the message we sent during the Venus transit?

Re: [amsat-bb] ISS and NO-84 at the same time last night...

I'm sorry I missed it yesterday, but I was a bit under the weather. I'll try to be out for tonight's passes. I'd like to get NO-84 in the log. 73 Rick Tejera K7TEJ Saguaro Astronomy Club www.SaguaroAstro.org Thunderbird Amateur Radio Club www.w7tbc.org On June 23, 2016, at 07:19, "Patrick STODDARD (WD9EWK/VA7EWK)" <amsat-bb(a)wd9ewk.net> wrote: Hi!

I was able to make quick QSOs with NP4JV (Fernando is in southern Arizona, near the USA/Mexico border) and KG6BFD in California.

I will be out this evening for the west-coast ISS and NO-84 passes around 0055-0125 UTC (5.55-6.25pm PDT). This time, the two will not pass over at the same time, so there will be a chance to make QSOs through each of them during their passes.

My TH-D72A won't show freeform text entered into a terminal program, but will display (and store) APRS messages addressed to my call. From a terminal program, you could send me APRS messages using this format: :WD9EWK-9 :Message follows the second colon A colon goes before my call sign, a space and a colon follows the call, and then the text of the short message. My replies to you would appear in this format, with the other station's call in place of WD9EWK-9. 73!

ISS and NO-84 at the same time last night...

SWAYAM beacon, text and sound record
by Jean-Pierre Godet 23 Jun '16

23 Jun '16

Hi my friends, The SWAYAM 437.025 CW beacon was received here in western Europe this morning, begining after 0950 UTC, orbit number 20: five characters strings received, each string, lasting maybe ten seconds, including twelve Morse characters, the strings being spaced from each other by about one minute and a half: SWAYAMSNBNNN SWAYAMSNVNNN SWAYAMSNMNNN SWAYAMSNUNNN SWAYAMSNSNNN (only the ninth lettre changes, the one before the three last NNN) Here is a short sample of the record: http://f5yg.pagesperso-orange.fr/incoming/SWAYAM_orb20_23jun2016.mp3 I removed the large intervals between each CW beacon strings to shorten the file. I apologize for the lack of Dopper shift correction as the frequency and tle need now to be adjusted more precisely. :-) Best 73 ! Jean-Pierre F5YG

A frugal approach to portable space APRS ops
by Fernando Ramirez 23 Jun '16

23 Jun '16

Good evening, For the past couple of weeks, I’ve been "experimenting” by using an Icom IC-2820h, an Elk Antenna, a Mobilinkd Bluetooth TNC and APRSDroid on my phone, to work the International Space Station digipeater (and PSat). I am happy to report that it works! I have made several contacts, some that have provided me with new grid squares. Besides the radio, the rest of the setup can be a budget friendly alternative to $500+ APRS-ready equipment. The Mobillinkd TNC, plus cables, can be obtained for less than $100 dollars. I prefer the Icom transceiver due to local RF sources that overwhelm the front end of cheap Chinese handheld radios. I am positive that better handheld devices will work just fine. The TNC is connected to the radio via the audio or data port and connects to the Android device via Bluetooth. The 2820h uses a DIN6 connector cable, compatible with other radios such as the Yaesu FT-817 and 857. APRSDroid acts as the main interface and has features that you will find on an APRS radio. Just enter the correct path and you will be able to work terrestrial and space APRS. The TNC can also be connected to your Bluetooth capable computer (dongles will work). I tried it with UISS and AGWPE and it worked perfectly. Today, I was able to work a simultaneous ISS and PSAT pass and heard packets from both spacecrafts. I saw messages from stations from Canada to Mexico and worked WD9EWK in Phoenix, 259 km north of my QTH. I also heard double-hop packets from K5UBQ in Texas and XE2OCM in Monterrey, Mexico. 73!
