Hi guys,

I am posting this question over here on elmers because I did not get any help with
it in the Satellite section..
I tried to delete it from the Satellite section, but I did not see that option..
so..Sorry in advance for the double post....

What do i need so i can do packet with the International Space Station on 2 meters
with my older Kenwood TR-9130 ? if possible...

thanks,
Kevin Rea

I learn something new every day. packet comms with the ISS this I gotta try.

reference http://www.ariss.org/contact-the-iss.html

I do not have this radio, but I believe you would need the following:
1) Rigblaster Advantage (soundcard) or Signalink (soundcard), both wired into the microphone of the radio for PTT and audio input.
2) take audio from the radio using external speaker connection on back of radio. run this into the soundcard LINE IN.
3) software such as UZ7HO SoundModem and Easy Term.  (or some other software TNC and keyboard terminal) Soundmodem does COM port PTT so you will have to work out the PTT line making use of a isolation method such that the radio and computer are not electrically connected.
 
I set up my VHF mobile radio (Yaesu ft 7900R)  for 1200 baud packet using the soundcard on my PC  and used the Rigblaster NOMIC for PTT.  I made an isolated audio line to get radio audio into the PC sound card.  (use LINE IN on back panel, not microphone). I will have to try the ISS sometime.

And as the ariss article says, you need a directional beam that you have to aim at the ISS. or Omnidirectional 1/4 wave ground plane antenna might work.

good luck and 73

If you need the pinout for the microphone jack, I found this.

ok so the software needed for ISS specifically may not be Soundmodem, but instead, a couple of others as detailed here.

WD9EWK is THE guru regarding packet QSO's through ISS.  He has forgotten more about the topic than most of us will ever know, and he's a terrific Elmer (I am speaking from first-hand experience).
