<br>
The integration of the LX0OHB-4M amateur radio payload was completed<br>
on Sunday night, October 12 and is now ready to launch<br>
<br>
<br>
The onboard clock has been adjusted to start JT65B (145.980 MHz) at<br>
the UTC minute +/-1 second. It is likely to drift during the mission,<br>
and manual offset introduction will be required after a week or so.<br>
The launch date is October 23 at 1800 UTC.<br>
<br>
Beginning of transmission of 4M will start between 1917 UTC and 1927<br>
UTC. Refer to the provided maps and animations links in the blog<br>
section (see also older messages) to determine your visibility.<br>
Alternatively, use the ‘tracking’ section where you can compute your<br>
tracking elements by introducing your geographic coordinates. The<br>
table can be copied/pasted into a text file. As the apparent movement<br>
will be close (and closer) to the one one of the Moon, manual pointing<br>
is easy but for the largest arrays. We’ll try to publish equivalent<br>
TLE’s to input in usual tracking software.<br>
<br>
The link budget is quite tight, but the first hours should give<br>
comfortable signals. QSB is to be expected.<br>
<br>
As JT65B is used: please remind those not yet too familiar with it<br>
that the receiver must not be tuned during the transmission. A<br>
dedicated webpage is being written to detail the procedure.<br>
<br>
A dedicated java application is also available to automatically<br>
transmit the decoded messages to the 4M website and ease the data<br>
collection. (Thanks to LSE Space). Alternatively, you can also send<br>
the decoded messages by eMail, sending the ALL.txt file.<br>
<br>
For those not wishing to use JT65B, please record the signals<br>
(11025s/s, 8or 16 bits, mono), taking care not to saturate the<br>
recording and NO MP3 please.<br>
<br>
SpectrumLab is an excellent choice, although some may wish to use<br>
simpler recording software.<br>
<br>
You can imagine that the team is quite eager to receive the first<br>
reports, so, do not hesitate to mail immediately, send decoded<br>
messages or even phone or text me at +352 661 678 986.<br>
<br>
Our friends of IC CMalaga are also quite eager to receive the results<br>
of their radiation dosimeter experiment.<br>
<br>
Basic rules of the contest have been delineated in the blog section.<br>
Complete rules will be published soon.<br>
<br>
Stay tuned on our website or Facebook page.<br>

The following is a tentative set of orbital elements that should<br>
remain valid from the launch to at least up to the October 27 when<br>
using usual classical and simple tracking software which does not<br>
integrate Moon.<br>
