I hear a lot of noise from GO32 on it's pass on the beacon downlink of 435.325 . It is supposed to be 9600bps , but I can't copy any packet . Is the noise the packet beacon ?

Probably. Ill try to take a listen today. GO-32 was abandoned a year? Ago due to frequent resets, but maybe they are trying to revive it. For the last two years of its useful life they enabled APRS style packet digipeating.
At 9600 baud, any of the APRS mobiles and HT radios could use it for global messaging and digipeating.

These days GO-32 goes into a strange "emergency mode" where it transmits something at 9600 (hard to decode)....when in this mode, it makes constant noise...not just your normal 9600 baud "sssshhhhhh...." sounds, either. The emergency mode sounds more like noise with distinct "clicks" in it at regular intervals (1 sec or so?)
When out of emergency mode, it tends to send 9600 telemetry packets every minute or (that's close...)

Unfortunately go-32 is end of mission! Mike DK3WN & I have been tracking this for a while now and it's solar panels cannot produce enough juice to keep the on board computer going hence why it enters emergency mode quite often :(
Shame as Bob did a good thing with Aprsing it!

This is no new signal. It's TECHSAT 1k2 PSK emergency beacon. See here: http://www.dk3wn.info/p/?cat=23
