Hello,
Regarding UO-11 there is an interesting audio capture on https://network.satnogs.org/observations/1390588/
Sounds similar to sample on http://www.users.zetnet.co.uk/clivew/u2rpt.htm
UO-11 can be tracked from http://amsat.org.ar/pass?satx=uo-11
73, lu7abf, Pedro
What caught my ear this morning was that the transmission was a steady stream of 1k2 AFSK not the usual packet burst of ISS or other PACSAT's. None of the usual satellites on 145.825 (i.e. ISS, PACSATs, etc) where in view when I checked as to what satellites might be view. After loading an element set for UO-11 and checked where it was, it's orbit matched the AOS and LOS I had observed.
I won't have a chance to check this evening for passes but will be able to have a listen again tomorrow morning.
I will see if I can decode any of datastream whether it makes sense or not.
cheers, Graham ve3gtc

You might want to make sure that XW-2D (#40907) is not in the area.
It can put out a lot of interference that bleeds into 145.825.

Good morning Scott,
Good point but no, it wasn't XW-2D. I considered that but that was not the case.

The signals on 145.825 are Uosat11. I have been copying data from the bird way back to the late 1980's with a tnc2 modem into a Commodore computer. This is when it was used to pass data during a Polar Trek. The signals were very weak when I started listening for it yesterday but as soon as I switched the antenna to LHCP it was booming in. Haven't tried any decode. Mike WA8EBM

It is definitely UOSAT11, using audio capture from: https://network.satnogs.org/observations/1390588/ using
MIXW @ RTTY 1200 bauds, 1200 Hz shift, ASCII 7 @ 1800Hz
Following was decoded: perhaps a good reception can get more
UOSAT/2 P 1? 1204101832000000b000102`0203000400040000500060vv&K009 l0000lp1000012000313012140051000416`0715000618000919008 20000Y21003Y200003300124006250007260004z700052\000!29&k 300003100232000133000034000735000636000537000438000B390A 40000441005tZ006430007440004500014600004700034800C490
Congrats to UO-11 Team, their bird back to life after 36 years

I monitored another pass this morning.
Uitmsat passed over just before AOS 2020-06-13 12:34 LOS 12:44 NO-84 also passed over just before AOS 2020-06-13 12:33 ISS also pass over but afterwards AOS 2020-06-13 13:02 LOS 13:18
UO-11 was expected to pass over AOS 2020-06-13 12:45 LOS 12:57
During this time I did track a signal on 145.825 +/- doppler. not as strong this morning on this pass as the signal I heard yesterday and I was unable to decode any 1k2baud AFSK data. This pass was over the Western part of the US and I suspect that it just wasn't getting as much sun as it did yesterday.
I am going to monitor another pass later today (late afternoon - early evening my time) and again early tomorrow morning.
Someone asked what software I was using to try and decode the telemetry. I am trying to use MixW32 as briefly described here:
https://www.pe0sat.vgnet.nl/satellite/amateur-radio-satellites/uo-11/ about 4/5ths of the way down the page.
At this point I am pretty certain that what I have been hearing is in fact UO-11
