> Dear Hoz Ueda and members of JAMSAT,

> Please accept apologies from myself and the JAISAT working team for troubling you with this correspondence. I am writing to you because we would like to urgently seek your help to enable us to complete the Joint Academy for Intelligent Satellites for Amateur Radio of Thailand (JAISAT) project.  We have encountered problems of insufficient funds which stem from the fact that in 2014 ISIS had quoted us a cost of less than seven million baht to build the JAISAT satellite. However, it turned out that this year ISIS quoted us the equivalent of nine million baht to construct the satellite, with the difference being due to fluctuations in the exchange rate of the Thai baht.

In this regard, we would like to urgently meet with you and other members of JAMSAT in person. This meeting could be in Thailand if you should happen to be coming to Thailand during this month of November. However, if you will not be visiting Thailand then we would like to make an appointment to meet you and other members of JAMSAT in Japan as soon as possible and ideally during this month (November, 2015). Here follows an outline of our plans:

> - Deployable UHF and VHF antennas

> For the CubeSat structures, we will create these ourselves in Thailand, along with the CNC equipment using the best AW-6060 aluminium alloy from Germany, and we would bring these components for assembly and testing in Japan. However, we need to find the following satellite components from Japan:
> 
> - Passive magnetic stabilization system for Cubesat
> 
> - Solar panels
> 
> - Battery pack 
> 
> 
> 
> 2. We would like to seek your recommendations regarding electronic components that have passed inspection and testing and which are capable of working in space in order to design and construct a prototype Linear Transponder in Thailand. Once this prototype is successful we will have it manufactured in Japan and conduct durability testing there.

We have a team to build the JAISAT satellite while one of our members, Mr. ApiwatJira, HS4SCI/KI1F or PAO san , is studying at Kyushu University and he will be able to help in the testing of the satellite. We don't know if you know anyone at Kyushu university or not? If you do, please advise us as soon as possible.
