Hello All AMSAT members in worldwide,
Before the New Year 2019 I 'm Tanan, HS1JAN and Khun Chawalit, E20KEW along with Khun Krisada, E21EJC visited Prof Dr. Suwat, the Knacksat Project Leader, and Dr. Pongsathorn, the Knacksat Project Team Manager at the King Mongkut Institute of Technology North Bangkok (KMUT-NB) to enquire about the status of the Knacksat satellite following its SSO-A launch by a Space X rocket on December 3, 2018.
Due to problems with the Space X rocket, the launch had been postponed several times with the Knacksat satellite being kept on hold and the satellite's batteries may have become depleted by the time the satellite was finally launched by SSO-A. When the deploy switch has been working for about 30 minutes the VHF/UHF antennas are deployed with heat from the nichrome wire. https://www.facebook.com/knacksat/videos/818456401588168/
This creates a need for high-voltage electricity which may be the reason that Knacksat satellite batteries had lower power than normal. If this were the case Knacksat satellites would then enter "Save Mode", or a sleep state, in order to charge the battery and to await orders from the HS0AK Ground Station.
We are confident that the Knacksat satellite is still in a state of sleep. The Knacksat team expects that it may take up to many months to charge the battery to get to the original energy level. Hence, I would like to ask amateur radio operators in the AMSAT group to help the Knacksat team as well.
The Knacksat team needs urgent help in receiving reports of the CW beacon signal on the frequency of 435.635 MHz because the Knacksat satellite will send the CW Beacon signal when the solar cell panel receives enough sunlight to charge the battery. Hence, there may be a signal from the CW beacon with the power of just 10 - 100 mW from the Knacksat satellite at any time.
The Knacksat team has prepared rewards for anyone who sends them details with a signal report received from the Knacksat satellite including QSL cards, and Knacksat shirts, etc. Anyone who copies the satellite should please send an email to [email protected] or enter a report at this website: https://knacksat-26d23.firebaseapp.com. Details can be found at http://www.knacksat.space/
Since the satellite was launched about one month ago only two persons have received signals of the CW beacon and the signal has been very weak such that the CW could not be fully copied while the telemetry could not be fully decoded. Therefore, we would like to make an urgent request for amateur radio operators to study the information below and to please get in touch by email with [email protected] to help the Knacksat team.
1. The need is for an amateur radio station with an antenna with the EME level of gain to help. The UHF frequency at 435.635 MHz requires an antenna with a very high gain to receive the very weak CW beacon signal.
2. The need is also for an amateur radio station equipped at the EME level with a high-gain VHF antenna to try to send the sound (MP3) for command change mode uplink VHF frequency. that will wake up the Knacksat satellite from being in Save mode.
Therefore, if any AMSAT member knows of anyone or can help or who can co-ordinate efforts to contact or is capable of receiving signals from the Knacksat satellite, could they please get in contact with the Knacksat team as quickly as possible.
Thank you in advance for helping the satellites of Thailand. In the near future and not later than the second quarter of 2019 (Q2) the JAISAT-1 (“Joint Academy for Intelligent Satellites for Amateur Radio of Thailand.”) satellite will be launched into space and we will keep you informed of progress with further news.
