8 August contact to Youngsters on the Air (YOTA) !

An International Space Station ARISS contact has been planned for astronaut Paolo Nespoli, IZ0JPA and the Youngsters on the Air event, which takes place at Gilwell Park this week.

The ARISS contact is scheduled for Tuesday, 8 August 2017 at approximately 1838UTC.

This will be a direct radio contact, operated by GB4YOTA, and downlink signals will be audible in many parts of Europe on 145.800MHz narrowband FM.

Paolo, IZ0JPA will operate the HamVideo transmitter.

The Goonhilly receiver will be activated sometime on 4 August 2017 and will remain active over the weekend, continuing to track the ISS until the morning of the 9th.

Two internet video streams will be available.

The main YOTA event stream is at https://ariss.batc.tv and the ISS contact stream, starting at around 1740UTC on Tuesday, will be at https://ariss.batc.tv/hamtv.

You can also watch the ISS contact live on the RSGB’s YouTube channel at www.youtube.com/theRSGB.

call sign confusion

I think Paolo just misspoke when he included the "I" in the call sign. Several of the ISS call signs end in "ISS" but the US call suffix is only "SS".

NA1SS, RS0ISS, OR4ISS

Re: call sign confusion

Paolo used NA1SS when calling and signing off from GB17YOTA ARISS contact 20:14 UTC on 2nd attempt using Kenwood D710 in Russian Service Module as heard at beginning and end of this recording.

I can understand Rudy confused and preferred if he used an European callsign instead coming from his home country Italy.
I was very happy when he used this callsign as it's the first time for me of hearing NA1SS from the ISS which is seldom used over Europe.

I also heard him very briefly calling NA1SS 3/4 through the first pass 18:37 UTC on Ericsson VHF when using HamTv in the Columbus Module when audio failed on the downlink.

Use of NA1SS over Europe?

Hi!

For those that remember when Doug Wheelock was on the microphone from the ISS in 2010, or Bill McArthur back in 2005-06, I thought those guys used NA1SS for all of there contacts around the world. Wasn't that the case over Europe? For the scheduled events, I'd guess that the non-US calls would get used more, unless it comes down to a request or an issue with third-party traffic (i.e., non-hams on the mic talking to the ISS crews).

Other than on packet or maybe SSTV, RS0ISS is a rare one over North America. I have one voice contact with RS0ISS, done as part of an ARISS radio test one early December morning in 2013:

NA1SS used for GB17YOTA ARISS QSO

Hi!

I think NA1SS was used since the US has a third-party traffic agreement with the UK when the UK stations are using call signs with GB special-event prefixes (except for GB3 prefixes). GB17YOTA would fall squarely within this agreement, so that is why I could see the reason for using the NA1SS call sign yesterday. If everyone who talked to NA1SS had a ham license, the US FCC would not consider that "third-party traffic", since they could have talked to NA1SS with their own call signs. I don't know if the UK's Ofcom shares the same opinion on what is or isn't considered "third-party traffic".

73!
