[amsat-bb] urgent help from AMSAT members worldwide

[Tanan Rangseeprom]

Dear Paul Stoetzer, Executive Vice President of Radio Amateur Satellite
Corporation (AMSAT-NA) and member of AMSAT-BB

 The Radio Amateur Society of Thailand under patronage of His Majesty the
King (RAST) would like to thank you for the SatPC32 program along with the
Registration Code for the HS0AJ Ground Station. I and members of RAST along
with the team building the JAISAT-1 satellite used your program to control
the Rotor with a V/U antenna to work automatically in order to receive
signals from amateur radio satellites that passed over Thailand. We have
posted a video on YouTube of this, along with audio from an IC-9100
transceiver, which you can view by using the link below or by searching
YouTube for the callsign HS0AJ.

 We have made an application to the Thai regulator, the National
Broadcasting and Telecommunications Commission (NBTC) to set up ground
stations in different regions of Thailand in four locations, from North to
South and with the following callsigns:

 1. GS station in the North of Thailand, using the callsign HS0AN

 2. GS station in the South using the callsign HS0AS

 3. GS Station in the Northeast of Thailand using the callsign HS0AO

 4. GS station in the Central region of Thailand with the callsign HS0AL

We intend to post videos from all of these stations on YouTube, similar to
those from HS0AJ, and we will establish ground stations all over the
country in order to receive signals from satellites and to enable amateur
radio operators and others in Thailand who are interested to access videos
from these stations on YouTube.

However, now we are seeking urgent help from AMSAT members worldwide
because we are unable to contact the company Innovative Solutions In Space
(ISIS) with which RAST had signed a contract to buy components for a
U-class CubeSat but excluding the payload, being the Linear Transponder.
Since the beginning of this year up until now we have been unable to
contact ISIS, which is the reason for this appeal to you for urgent help in
the purchase of components for the Flight Model of the 1U CubeSat satellite
which is capable of carrying a payload of a Linear Transponder for RAST and
which has been assembled and has passed the testing phase.

Can anyone please provide some recommendations to us regarding the assembly
of the satellite – and as quickly as possible? RAST and its members are
lacking experience in satellite assembly and for the initial testing phase
and we are appealing for suggestions as to where we can find suppliers of
CubeSat components and as to who can test them and send the satellite out
into space?

For your consideration, please find some YouTube links about testing and
building a Linear Transponder below:
