Matt,
I haven't received any reports from the 0610 pass. It was going to be a max elevation of 1 or less at our ground station. The two passes before that AOS was about 4 minutes behind #31126 and probably 30-60 seconds behind P-POD C keps from the launch. Tracking P-POD C kept the antenna's main lobe just ahead of the sat.
As far as the workshop is concerned, most of the team is in California as of last night. The original team members, me, Wade and Shawn will not make it.

Hi Jonathan,
We plugged in the latest Keps and were looking behind #31126 for 1.5-3 minutes, but nothing was heard. It could be that we just didn't pick up the beacon, but I'm curious--did anyone else report reception to you at or around 0610 UTC today (4/19) ?
We'll continue tracking when we can, but we'll be pretty busy at the Workshop this weekend. No doubt the recent deployment is keeping you busy, but were you or any of your teammates attending this weekend?

Matt,
As long as the satellite is still healthy, the CW beacon should be active. The latest reports are saying that CAPE is trailing object #31126 by 1.5 - 3 minutes and is close to the preliminary P-POD C keps (I think they're still on the cubesat.org website, if not let me know and I'll dig them up).
Thanks for tracking,

Hi Jonathan,
We were listening to the afternoon pass here in CA (around 1900 UTC I believe), but we were only
tracking
the first objects listed on the website (A-E). Now that we have your object ID, we'd be happy to
listen
and make recordings tonight on the 0610 UTC
west-coast
pass (60 deg max EL here). I was unable to find an operations plan on the CAPE-1 website at first glance--can you please verify that the CW beacon should be active at 0610 UTC?
Thanks Jonathan. Congratulations to you and your
team
on a successful deployment!

Hi all,
We are trying to gather a full snapshot of 3 CW beacons from CAPE-1 to get an idea of the health of the satellite. Part
of
the problem is that we don't know exactly where CAPE-1 is located. TLE's are available on W0RPK's website http://showcase.netins.net/web/wallio/CubeSat.htm about half-way down. We managed to hear a weak signal starting about 435.254 MHz and ending around 435.237 MHz tracking object #31126. We've obtained some information that CAPE may actually
be
a little behind this one even, but we're not sure.
The satellite is transmitting CW and 9600 baud G3RUH, but currently we are primarily interested in the SSB CW. Also, if you have the capability any recordings are more than welcome. Recordings can be sent to jonathan@jonathanwagner.net If the recording
is
too large, send me an email and we'll figure out how to get it
across.
The CW beacon we are looking for the most is the beacon 1 which
gives
us an idea of battery health. The telemetry format is
available
at http://ulcape.org/wiki/CAPE1_Telemetry There are
a
few audio examples at DTUsat's webpage http://www.dtusat.dtu.dk/index.php?id=94 The
second
file labeled Unknown.wav is what the G3RUH data sounds like in SSB mode and has been confused as the letter N. After that signal ends, the next CW beacon is about 10-20 seconds away.
The satellite is transmitting at 435.245 +/- doppler. Any help would be greatly appreciated. Again any recordings or decoded telemetry can be sent to me at jonathan@jonathanwagner.net
