Greeting from Philadelphia
This is SSB (Single Side Band ) Transmitter made by Elcom Reserch Thailand ( Elcom is sister company of G-Simmmond -Thailand ).
You should contact Dr. Rak Jira .
I am very sure that Dr. Rak whom is a very nice person could give you the circuit diagram.
Elcom Reserach is a very old Thai Company for more than 50 year in Telecommunication but so sad that Thai Government in the old days
do not understand the real international business .
If not Elcom Research should be bigger than a lot of Taiwan computer company or Samsung by now.
This is one of the earliest wholy Thais own company in the old day .
They also used to be ICOM radio , Hewlett Packard HP ,etc
A lot Transceiver for Police , Department of Communication , Border patrol police , Royal Thai Army been supplied by Elcom Research befor.
Now Elcom Research supply DTH Satellite antennna to UBC (True Vission).
Another so sad UBC recently purchase DTH Satellite disc from China.
My computer have problem then reply with Hotel computer .
I should be back and reply in Thai soon.
TC
