To add to Patrick's advise, you can store up to 8 user phrases. APRS menu 3P0. Mine include "CQ De K7TEJ from DM33, pse K", "K7TEJ DM33, QSL" And "K7TEJ 73". (These can also be entered in the programming software"
To use, press MSG and enter or select the call sign you wish to contact, in the message text line. Press "F", this will bring up the list of messages, press the number of the stored message, and it will paste in. Press the right side of the multi function button and away it goes. If successfully receive, you get a message back.

As AI6GS mentioned, you can program a group of 5 memory channels that will compensate for Doppler on both the uplink and downlink for the 437.550 MHz frequency now being used for the ISS packet digipeater. That list is available at:
I also pinned my tweet from last week on my @WD9EWK Twitter profile page with the same chart, which you can see at:
As for using your TH-D72A for making QSOs using the ISS packet digipeater, you can use APRS messages to do that. You can define some messages in advance, so you aren't having to enter those messages on the HT's keypad, or you can do that. Typing on the keypad is just like sending SMS messages on a flip-phone or other "non-smart" mobile phone.
APRS messages are the way anyone working the digipeater can send and receive text that shows up on the screens of any station. The Kenwood APRS-ready radios will not display freeform text that someone using a simple terminal program types. APRS messages are sent in a format that contains the call signs of the two stations, along with a line of text intended for the receiving station.
Using APRS messages, you are able to make the same types of exchanges you would on any other satellite. Grid locators are the most common item exchanged, but with the prepared messages you might also send your name and/or location along with the grid locator. You could skip sending your location in the APRS message, if you are using the APRS functionality to beacon your location during the ISS pass.
More stations are giving the ISS digipeater on 70cm a try, and many are finding success using the 5-channel setup like I mentioned on this list last week. If you are set up to work the ISS 70cm digipeater by the end of the week, I will be on there from a hamfest near Tucson this Saturday (12 November) morning.

Just purchased a used Kenwood TH-D72A HT. Hoping to use it along with an Arrow antenna to make more satellite contacts while traveling. While I primarily expect to use it to make voice contacts on the FM birds, I’m also interested in making packet contacts through the International Space Station.
Could someone point me towards a programming guide for this type of application? Any other pointers in using the radio to make packet QSOs through the ISS?
Grateful for all suggestions.
