Hello Dante,
I live about 40 miles south of Raleigh--maybe I can help?
Please contact me directly and we'll see what we might work out.

Dear All,
I'm Hiroki Ashida at Tokyo Institute of Technology (JQ1YCZ) and I'd like
to inform you about our satellite's operation which starts very soon.
We're preparing for a long-run (continuous 12hour) of the APD (avalanche
photo-diode) carried on Cute1.7 + APD II, as a radiation monitor of
low-energy (E> 10 keV) particles trapped in the LEO (low Earth orbit).
While the APD is operating, the status packet of APD is transmitted
every 16seconds (TBD). The observation will start at 10:40, May 21 (UTC)
and the APD will be turned off on 22:40, May 21(UTC). So the APD
packet can be received everywhere in the world! This is the first time
that Cute-1.7 + APD II transmits its FM packet around the globe.
Though the observation data will be stored in FRAMs, we'd like to know a
real-time status of the APD during the observation. Your kind reports
will be highly appreciated.
FM packets are transmitted on 437.475MHz and packet formats are
available in the following web-page.
http://lss.mes.titech.ac.jp/ssp/cute1.7/fm_mode_apd_e.html
4A-51-31-59-54-43-3E-4A-51-31-59-43-5A-3A-D0-30-77-B8-03-16-99
For exapmle, according to an above APD status packet we can obtain
informations as;
4A-51-31-59-54-43-3E-4A-51-31-59-43-5A-3A : Header(JQ1YTC>JQ1YCZ)
D0 : APD Packet ID (Fixed)
30 : Status Code
APD Status : Operational
HV Status : Set Value = Output Value
Temp Correction : Active
Data Mode : Counter Valid
Detector : APD A
APD Gain : Gain 30
Threshold : 219mV
77 : Temperature
0x77 = 119 -> (119/255)*91.712-48.569 = -5.7 [degC]
B8 : High Voltage
0xB8 = 184 -> (184/255)*396.5 = 286 [V]
03-16-99 : Counter
0x1699 = 5785 -> 5785 * 2^3 = 46280
Latest TLE from NORAD is;
Cute-1.7 + APD II

Hello all,
Thanks for the many replies to my question. There were a couple with
quite a lot of detail.
I'll likely just go with the AIDC 3731 with 145 MHz IF mounted at the dish.
I don't
know the noise figure of my 123 MHz units.
I needed a 145 MHz IF in the AO-40 days, as I discovered that an original
Icom 706 (mkI)
has lousy sensitivity at 123 MHz. I've since upgraded to twin 706MK2g rigs
that hear
just fine at 123..
BTW, anyone have a ballpark idea of when P3E will launch? Last I heard was
late 2008?
73,

Hi Clint,
The Delfi-C3 (DO-64) beacon is on 145.870 MHz in CW and SWITCHED OFF
at the moment.
At the moment listen at 145.930. There is a telemetry channel there
with 1200 Baud BPSK AX.25.
The spacecrafts current status can be viewed on the mission operations
page at

Last the I have heard is they haven't secured a flight yet, so I wouldn't
expect it this year, and probably not next, either.

THANK YOU. Do you still want our pass reception reports - as described on your
