Help with APRS to ISS
Greetings all..
I am new to working APRS. I am seeing conflicting info about uplink and downlink freqs for ISS digipeater. Is it 145.825 up/down? I am seeing some things list 145.99 uplink. I hear the ISS and decode it fine on 145.825.
Second question- I am running UISS pro with the path set:
to: APEG02
via: RS0ISS-4
Is this correct? I am also running a satgate connected to the net. Can I still run the satgate while trying to digi through the ISS at the same time?
Thanks so much for the help!

The ISS does not do APRS
APRS stands for Automatic Packet Reporting System, which is a system developed by Bob Bruninga, WB4APR wherein location, information, and other data is shared on a network (usually on 144.39) using packet radio.
Packet radio uses (A)X.25 tone to pass data at 1200 and/or 9600 baud, usually though a terminal node controller (TNC).
The radio on the ISS is a packet station, and has nothing to do with APRS.

Kenwood D700 on ISS
The ISS has a Kenwood D700 which is a APRS capable device. You are correct that the ISS does not utilize this capability and mainly acts as a digipeater. I think the hardware type contributes to a lot of the confusion between packet and the subset operations of APRS.

D710
So on a D710 would you set the TNC to APRS or Packet to contact ISS?
APRS or PKT
Either. They are both using AX.25 protocols but you will likely find it easier to use the APRS settings instead of hooking up a computer to the radio to take full advantage of the PKT settings.
Re: Help with APRS to ISS
Hello Matt,
ISS aprs/packet system works on 145.825Mhz (FM/N) simplex.
The old uplink 145.990Mhz not used for a long time
anymore (sadly people leave that freq. on their website).
If you install UISS for the first time you will see the path:
To: CQ
Via: ARISS
People should not chance that settings.

Question about how to prepare an APRS contact via ISS
Hello !
I just started working in APRS and there are a lot of things that I try to understand when it comes to make a contact via ISS. I have a MAAS AHT-2UV transceiver connected with a pair of audio cables to a Android phone, which runs APRSdroid application. For "terrestrial" APRS, all it is perfect, I can receive and transmit APRS packets without any packets, using normal DIGI PATH WIDEn-N.
Now, my question is: for ISS operation, the DIGI PATH field im my application sould be set with the following string: UNPROTO CQ VIA ARISS ?
Thank you !
Best 73 !

If you replace WIDEn-N with ARISS then you should be ready to go.
It works !
Thank you Ken for the hint ! It works perfect !
APRSdroid
I have question about APRSdroid is possible this apps can make contact with ISS? and how to setup with my smartphone.
Thank you

APRSdroid
Hi !
Today was the 3rd time when I succeed to sent packets via ISS, using APRSdroid 1.2 and portable whip antenna in 5w transceiver. Now, I'm a beginner in this area and I'm not sure if that means to make a contact with ISS. But, I think that the packets were received via ISS because YU7RD and YO8BMF confirmed me this:
2012-10-29 06:48:05Z
YO8BMF>APRS,RS0ISS-4*,qAR,SR5GK-3::BLNQSL1/1:YO3FVR-7,YU7RD,DO1BFS{UISS52}
2012-10-29 06:46:49Z
YU7RD>APRS,RS0ISS-4*,qAR,SR5GK-3::HEARDlast:YO3FVR-7,IK1COA-2,DO1BFS,IW3RGK,IK3ZGB-2,SP9MZM-6{UISS53}
Anyway, the main settings for APRSdroid ar in the APRS Connection section:
a) Connection Protocol must be set with: AFSK via Speaker/Mic
b) Connection Preferences / APRS digi path: ARISS
I used a HTC Gratia Smartphone, connected directly with the VHF transceiver, using a dual audio cable. On the transceiver side, the VOX is enabled, in order to activate the PTT function.
Unfortunately, not every smartphone can be used with a direct connection via audio cable ! In this case, the speaker's phone must be placed near the transceiver's MIC (also with VOX function enable) and the transceiver's speaker output level must be set at a proper value in order to be "heard" by the APRSdroid.
The APRSdroid provides a Bluetooth TNC function but I don't tested !

Good Info
hi, Catalin
Thank you for information i am very appriciated that give more knowledge about APRSdroid. I will tried this soon.
