Can anyone tell me if the ISS is still using VOICE mode ?
They flew right over CT, and I heard nothing, unless they were
busy doing some experiments or work on board. I noticed on this
website, that the ISS has been making lots of PACKET contact..
I have my radio set to 144.49MHz on TX and 145.80MHz on RX.

ISS active on this pass

I can confirm the ISS was active on this day for this pass but the ISS was using 144.49 as the downlink freq. I do not know what the uplink was.

I was in Norfolk, VA on this day and set up with 144.49 as the uplink and 145.8 as the downlink. This was one of my first times to try to attempt the ISS. I turned the volume down on 144.49 and began calling on the uplink. Soon, I noticed strong signal bars on 144.49 which I ignored for a time (I wish I had not now!) under the assumption it was someone local. When I didn't hear any response on 145.8, I turned up the volume on 144.49.

It was not evident at first that it was the ISS until I heard "we're right over KY now" and then a short time later "we're coming over Maine". From what I heard, the crew member referenced "dad" in the conversation and he said that hopefully they "could do this again" before he comes down. His dad (I presume) was using a beam on the ground that he was experimenting with at pointing. I surmise they flipped the up/down links so that they would have a clear frequency free from everyone calling.

Whenever I go out to attempt the ISS now, I make sure I am listening in on 144.49 as well. I did not think it was the ISS because I was set on the published frequencies and I had no idea the signal could come in that strong. My meter was full bars on receive. I did call a few times on 145.8 to test to no avail.

André Kuipers was active this

André Kuipers was active this evening with PI9ISS. André heard me, but I had a few PSU-issues with my SSPA.

André Kuipers was active...

What time UTC was he active ??? and over what area was he active. I am just curious. Thanks

Crew awake times

Even if the crew were interested in talking on the radio, they are asleep at 2300 UTC. They typically are awake from 0600-2130 UTC.

here is a link to the ISS work schedule/timelines that may help give an idea as to what they are doing and when. It is the daily schedule that is posted on NASAs site.

I think it's this crew. I have heard them twice and both were school contacts.
They may not be as interested in ham radio as some to the other crews have been.
I follow the crew on twitter and I have sent messages to them with no response.
I think they change out three of the members at the end of April.
Maybe the crew following them will take more interest
I still keep listening and waiting for a chance to call them though.

I think you are correct. I

I think you are correct.
I think we were spoiled when Commander Wheelock was onboard :)

Voice from ISS

I have been tracking many passes over Western North America, (locations in So. Cal and in Central Oregon) and have not heard any voice communications in the past month. More than likely they are not near the radio, or they are busy, nor is the repeater active. I have attempted calls on the uplink freq. but no response. There is lots of packet on 145.825 but I don't have equipment to decode it yet. There is a link here 'APRS Tracking' to see the packets being passed through the ISS, but you've probably already seen that.

Bottom line is over North America is seems they are not online for voice. which is a bummer, so your not alone.

I should have also stated that my attempts have been at all hours of the day and night in the previously mentioned locations, I work graveyard shift from 2300 PDT (06:00 UTC) to 0730 PDT (14:30 UTC) so I am usually trying to catch them durring that time frame, which is about the time they start waking up and doing their daily routines.

It's all a matter of timing and patients as to when and IF you will catch them. Good Luck, and keep trying...
