Hi Patrick,

IRVINE01 is sending "IRV1" every 41 seconds. You can here a sample here: http://www.dk3wn.info/p/?p=90767

Hey Roy,

This is the third harmonic of "DB0WA", which you can see (and also hear) in this waterfall.

There might be some CW between 300 and 400 sec showing IRVINE-01, but unfortunately this is not audible.

Best regards,

Patrick, DL4PD

Check out the audio of this Satnogs observation: https://network.satnogs.org/observations/320591/

There is CW, followed by some digital. I don't know CW, so can't confirm that it's actually Irvine-1. But if somebody can confirm, then it's likely that what follows the CW is also from the same sat.

Hi, Has IRVINE01 sent any telemetry, or only "IRV1" in CW ? Their IARU filing at http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=504 mentions it will transmit "9k6 FSK with AX25". Has anyone heard 9k6 FSK from IRVINE01? 73, Douglas KA2UPW/5

My observation of that 2038utc IRVINE01 pass produced the expected CW of "IRV1" and the signal was much stronger than yesterday, so that's great news!

... as for possible 9k6 data on this pass, it wasn't remotely strong enough to decode but there were definitely some data bursts in there! Here is the best that I could do to capture an illustration of what looked just like 9k6 FSK on this pass, but again, you really had to be watching for it:

https://www.qsl.net/k/k4kdr//images/2018-11-12--2038--irvine01--hdsdr-9k6.pn...

(a still picture like this doesn't do justice... in real-time it was clearly a data packet)

... hopefully the strength of those 9k6 packets will increase to the point that they can be decoded.

The "CW" code in that Satnogs observation at

https://network.satnogs.org/observations/320591/

is "DB0WA" which is not what I was expecting from IRVINE01. The expected CW ID from IRVINE01 is "IRV1". There's also some kind of data, but it doesn't sound like 9k6 G3RUH AX.25. The audio spectrum cuts off about 3500 Hz (that is, there is almost no audio energy above about 3500Hz).
