Hi all...

Not sure if you have had this payload running all day today...I have had only a partial decode in the morning and nothing since...

What a difference a day makes...yesterday managed to get quite a few decodes into the evening...

Getting some decodes now.....8:00 utc and beyond

Andy, noticing the jt9 transmission has moved frequency a bit ??

PS-25 is up ...........................

Prediction:

[ZL1RS]

... for the 20m/30m WSPR followers, I believe the WSPR callsign used by balloon PS-25 is VK3ANH.

(VK3YT was on WSPR today, but on another short flight balloon).

PS-26 was released with PS-25 with identical configuration for multi-payload tracking testing.
It descended shortly after leaving the coastline.
Multi payload tracking on JT9 was successful, which was helped by the narrow bandwidth of the protocol.
