Hi Jerry:

I love my 72A. If you have RT Systems software, email me and I will send you the file that you can import into your software and download it into the radio. Brad KC9UQR

Thanks, I have the HT all set to go for later tonight. Once I get the station going full bore, I am going to try an contact Brad, KC9UQR
who lives on the other side of Lake Michigan (Unsalted) from me.

Tonight I can only use the 19" whip. My home brew 2M, 8' boom, 7-element is in the garage and will not be able to set it up tonight.
I have a few adjustments to make on it and its already dark and getting colder tonight. I'm going to pull it down from the storage tomorrow
and set it up permanently. I was impressed with the results of using it when the ISS came over and contacted one of the local high schools.

Thanks Clint,
 
I am going to try it tonight for AO91 when it is in my area at 23:23 to 23:35 EST local time.
Thanks again for all your help and quick response.  That is why this hobby is the greatest with
hams helping other hams. I appreciate it.

Summarizing for the Kenwood TH-D72a ... 

-Use VFO B for TX
-VFO A for RX (it has better sensitivity)
-balanced audio all the way to VFO A
-open squelch for VFO A 
-5W transmit
-DUPlex On

The frequencies at work-sat.com are there for you ... You can simply be in VFO mode for both A and B.


Re: Another ISS SSTV Project?

Hi Brad,
Have not talked with you in a while. I need to contact someone who may have the Kenwood TH-D72A to walk me through the process of setting up the HT for the SATS.
Having some difficulty and need someone that has the same model so we can discuss via e-mail or phone call.

Thanks,

Jerry...W8RQM

All that is needed is an HT capable of receiving 2 meters and a rubber duck antenna. Then you need an interface to decode the signal. Some people do this on a computer and others do this on their cell phone, with an app. I use SSTV app on my iPhone. I’m sure Android has an equal app.

Of course, if you have a better 2 meter antenna, your image will be better. Try it. It is fun.

Hi Clint,
I down loaded the Robut36, but then it asked me to allow Robut36 to
access photos, media, and files on my devise. Do I really want to do that?
Why would it ask for things of privacy?

Clint,
Is there an APP for the Android phone to view the SSTV? Is the HT suppose to be connected to the smart phone and if so, how?

That is for SSTV reception. Very few opportunities that past couple of years for 2m FM voice contacts. Watch ARISS and ARRL for possible projects.

What is the min equip I need to receive SSTV from ISS?  I always listen on a pass but have never had a voice contact since I don’t know their schedule.

Possible ARISS SSTV operation before year's end

ARISS reports the possibility of a worldwide commemorative SSTV operation from the International Space Station on Friday, Dec. 27 or Saturday, Dec. 28 and following days. 

The SSTV downlink frequency is 145.800 MHz. ARISS will provide more information as it becomes available. Watch the amsat-bb and follow @ARISS_status on Twitter for updates.

An SSTV system is an integral part of one of the ARISS ham radio stations, NA1SS/ RS0ISS in the Service Module. It transmits and receives JPEG still images. This system utilizes the Kenwood D700 and D710 radios and the ARISS antennas mounted on the Service Module. 
The SSTV equipment also includes SpaceCam and MMSSTV software, a radio/computer interface module and data cables. A Kenwood VC-H1 is also used to provide near real-time automatically transmitted images once every 3 minutes, when active.

A Kenwood D710 radio located in the Service Module was deployed by the Russian Space Agency, Energia to provide extended support of imaging experiments using various SSTV formats. It employs SpaceCam and MMSSTV software to transmit stored images.

The current Expedition 61 crew aboard the ISS includes Dr. Andrew “Drew” Morgan, KI5AAA, an emergency physician in the U.S. Army; veteran pilot Cosmonaut Alexander Skvortsov, RK6ATR; Luca Parmitano, KF5KDP, an Italian Air Force officer, pilot, and engineer; pilot Cosmonaut Oleg Skripochka; biologist Dr. Jessica Meir; and electrical engineer Christina Koch.
