Pleased to confirm that the FM repeater on LilacSat-1 is alive! My transmissions were clearly visible in my SDR waterfall when they were repeated.
I didn't have a great setup on the RX side this first try as I had to use a regular RTL-SDR with the linux GNU Radio decoder. But even with that I was able to decode a ton of telemetry and heard parts of N6RFM when he was being repeated.
I have an ace in the hole as I was recording with an SDRPlay on Windows. So, I'll replay that now and see if there was really more to hear on the downlink than I realized when working the pass "live".
Just wanted to get this note out for anyone interested as quickly as possible.
Here's a tweet with a screen shot but don't laugh at the little RTL-SDR's struggle to deal with my transmissions. When I was not keying the mic, you can clearly see the downlink right where it should be around 436.510.
FYI, the demod in GNU Radio was using TLE's for the ISS which I would imagine are fine here on the first couple of orbits, but I'm not an authority on that kind of thing.
73!

Ray, Thanks. Gets confusing for sure, but I suppose that a good problem to have...

Lilacsat-1 is not one of the nine added last week. Lilacsat-1 was launched today (5-25-2017).
This week's KEP distribution will update who is who in the list of nine. Lilacsat-1 is still and unknown, but here are the TLEs based on ISS TLEs (you are correct) from http://lilacsat.hit.edu.cn/?page_id=594
LilacSat-1 1 25544U 98067A 17144.89781703 .00001573 00000-0 31242-4 0 9992 2 25544 51.6416 154.3996 0005308 189.3117 243.1127 15.53923882 58131

I see 9 QB50 birds added to the NASABARE set, do we know which one is Lilacsat-1? Or are we still using ISS keps still the separate a bit more?
