Received this certificate from Eric Guth, organizer of the QSO Virtual Ham
Extravaganzas. My presentation earlier this year was one of the most-viewed,
as the show posted the presentations for all to view!

Thanks to fellow hams who viewed, and to Eric for the acknowledgment and
support.

Sideways Satellite Show

Clint Bradford
 

Ever have one of those nights where everything just went weird in front of an 
audience? Well, MICROHams in the Puget Sound region was the "recipient of
weird Clint" tonight.

Although I have truly never given the exact same show twice - as each is 
customized to the group to whom I am speaking - I pride myself in having 
it fairly well "scripted" and under control. And always allowing for questions
any time. And although the club president Grant WB7WSD (former ARRL 
Northwestern Division Vice Director) just emailed me ...

"Thanks again for a great presentation and a lot of laughs tonight!  People
had a great time. I can see why your program is so popular. You and Karen
are quite a team and have quite a good routine!"
 
... so it looks like all went well. But attendees know otherwise. 

It started as pressed a wrong button within Zoom. Not sure what
occurred. Been Zoom-ing for more than a year. But I couldn't get
up and running. Thank goodness my wife, Karen (she handles the
Chat Room) was on the call - and kept the assemblage entertained
while I sweated out the Zoom stuff. Then the Chat Room exploded
with downright hilarious banter ...

Oh, and then we had a "Getting Started" satellite presentation ... (g)

Their Q&A kept us going for almost two hours. We had a great time.
Got a new member for the club - Glenn plans to join this week! Forgot
from where he was calling ... but was a first-time attendee there
specifically for the satellite show.

Approaching 120 total shows ... Don't fret, upcoming audiences in South
New Jersey and the University of Arizona: I'll have it all back together by then.

Upcoming ISS / ARISS Projects in US

Clint Bradford
 

If you are near any of these nine campuses, NOW is the time to 
volunteer your talents and expertise! These ARISS projects are a 
year's worth of work for a 15-minute contact. Check out ... 
 
http:///www.iss-flabob.com
 
... to see what kind of preparation produces positive results for these students!
 
===================================
 
US Schools/Groups Move Into Phase 2 of ARISS Selections

May 13, 2021 — Amateur Radio on the International Space Station (ARISS) is pleased to announce the schools/host organizations selected for the January-June 2022 contact window. A total of 9 of the submitted proposals during the recent proposal window have been accepted to move forward in the processes of planning to host a scheduled amateur radio contact with crew on the ISS. The primary goal of the ARISS program is to engage young people in Science, Technology, Engineering, Arts and Math (STEAM) activities and raise their awareness of space communications, radio communications, space exploration, and related areas of study and career possibilities.
 
ARISS anticipates that NASA will be able to provide scheduling opportunities for these US host organizations.  The candidates must now complete an equipment plan that demonstrates their ability to execute the ham radio contact. Once their equipment plan is approved by the ARISS technical team, the final selected schools / organizations will be scheduled as their availability and flexibility match up with the scheduling opportunities.
 
The schools and organizations are:

Organization                                                                              Location
Bellefontaine High School                                                          Bellefontaine, OH
Carter G. Woodson Middle School                                            Hopewell, VA
Lewis Center for Educational Research                                    Apple Valley, CA
Matinecock District, Suffolk County NY Boy Scouts                  Medford, NY
McBride High School                                                                Long Beach, CA
Old St. Mary's School                                                                Chicago, IL
Salem-South Lyon District Library                                              South Lyon, MI
Sussex County Charter School for Technology                          Sparta, NJ
Space Hardware Club                                                                Huntsville, Alabama

ISS QSL Cards!

Clint Bradford
 

Don’t forget to receive (pun intended) your QSL card from the ISS!

If you don't actually make it through the crossband repeater - but just 
HEAR it - that STILL qualifies you for the gorgeous ISS QSL card!

Re: Help with Orbitron

NATHAN CIUFO
 

Thank you to both Clint and Floyd!  I was actually able to get the downlink tracked using GPredict and a Virtual COM port from the Kenwood website.  Now just working on getting the TX tracked with an 817 using GPredict.  Getting closer !!!  

Thanks to everyone and hope to work you on the linears soon!

ISS Over SoCA Tonight

Clint Bradford
 

Jurupa Valley and region: A visible pass of the ISS tonight! 9:31 PM for six minutes.

Starts in the WSW, ends in the NE. Will be about 45 degrees above the horizon - a GREAT pass!

The ISS crossband repeater is ON - downlink 437.800. Frequency chart at work-sat.com

For the Kenwood part of the question, please find Don W6GPS - he is involved in the Kenwood-related Facebook groups. THE authority on all things TH-D72/74-related!


Re: Help with Orbitron

Floyd Bixler
 

I don't believe that you can change the frequency of an HT like you want to.  You will need to change the freq manually.  As for the 817 frequency being wrong, may you be referring to the doppler adjustment that Orbitron makes.  I use GPredict for my satellite tracking, and HamLib's rigctrl with bluetooth connection to my 817 for CAT.  I haven't used Orbitron for quite some time since it hasn't been updated for a long time, but GPredict gets updated regularly.  It's satellite frequencies are stored in GPredict.  There's a lot more help information for it than Orbitron.  I also have a couple SDR's and I use them with Orbitron and SDR# where I have to give the frequency I'm monitoring for doppler correction.  

I would suggest you go to www.Work-Sat.com where Clint (K6LCS) has a ton of information that will help you.

Good Luck and hope to hear you on the birds one day.

Help with Orbitron

NATHAN CIUFO
 

Hello to everyone on the group.  I have a couple quick questions for anyone using Orbitron:

1)  Has anyone been able to successfully control the downlink frequency using Bluetooth on a Kenwood TH-D74A handheld using Orbitron?  I have my 817 being controlled via a Bluetooth Dongle but can't seem to get the D74 to track the downlink.

2)  Where does Orbitron get the frequency and mode information for the different satellites?  When I double click between satellites in the list that I'm tracking, and watch the Rotor/Radio tab in Orbitron, the frequencies aren't correct.  Do I have to manually enter those, and if so, do I enter the frequency of the MIDDLE of the pass?

Best 73,
Nathan KA3MTT


Re: ISS Crossband Repeater

Clint Bradford
 

Update on the ISS crossband repeater. It should become active shortly after 1245 UTC May 7 (5:45 AM PDT). The APRS system will be off while the crossband repeater is on. A best guess is that the repeater will be operational for around a month before switching back to APRS mode.

Satellite Presentations - continuing

Clint Bradford
 

Just finished meeting the Austin (TX) Amateur Radio Club for a satellite presentation. They’ve 
been around for more than a CENTURY. They market themselves extremely well. And someone 
forgot to tell them that we’re suffering through a pandemic - as they are AVERAGING 6-10 NEW 
MEMBERS A MONTH the past year! We had TEN “first-time attendees” this evening!
 
https://austinhams.org/
 
What a great club - MANY thanks for the invitation. Board member Mark W5MPJ KNEW what 
was coming - and as soon as he saw my NASA Hawaiian shirt, he knew we were gone to have 
some fun while learning … several AMSAT members in attendance ...
 
And so it goes. Life as an AMSAT Ambassador. Have knowledge YOU would like to share 
with the planet? Want YOUR personality to come through and get others involved in this 
aspect of our magnificent hobby? Visit https://www.amsat.org/ambassador/ - An attendee asked 
how I developed my presentation. I pointed him to https://www.work-sat.com/presentations.html - 
a page that needs updating, but shows the methodology of creating a presentation that should 
keep folks’ attention ...
 
Tomorrow night, Central California. MicroHams 5/18. South New Jersey 5/26. University of 
Arizona 6/1. White Mountain 6/2 … and more presentations  lined up. Think YOUR CLUB 
might appreciate a “Getting Started Working Amateur Satellites” presentation? Send me an email!

Re: ISS APRS tips?

John St. John
 

Thank you Rob! 
I have had a few successful digipeats off of the ISS now. I think you are right that things were too busy when I tried the first few times. Everyone was excited about the radio being fixed :) 
Best,
John

I am relatively new to this but have had success with a path of:  ARISS, WIDE2-1.  I think you just need to keep trying.  I have read that there are a shortage of SGATEs and so it all depends on:

a) did your packet get received by the ISS and digipeated? and
b) did the rebroadcast from the ISS get received by an SGATE and passed to the APRS internet system?

To have success with both of those factors you need to keep trying!

I think that a path of "ARISS" is changed to "NA1SS*" by the ISS, you don't put that in your path, put "ARISS".

From your packet list in the second post above:

00:10:04:33 : K0KOC-7]3Y2S1Y,NA1SS*,qAO,WB2QGZ-10:'i4wl #/]=

I decode that as being at "00:10:04:33" hours, a packet of data from callsign "K0KOC-7" was received by the ISS and digipeated by "NA1SS*", that was then received by SGATE callsign "WB2QGZ-10" and passed to the APRS internet system.

I use a Kenwood TM-D700 and a Comet GP3 ground plane antenna with 25W.  Maybe less than 50% of my packets get to an SGATE per pass of the ISS.  I'm in eastern Ontario, Canada so unless the ISS is going south towards greater population (ie more SGATEs) then my success rate is low.

Hope that helps.

Just might be back on May 7, 2021!

And remember - it isn’t the TX power, it is timing (grin). Better results during off-peak hour passes!
