My first contact on AO-123 satellite, that too a DX!

Just now there was a pass of AO-123 amteur radio satellite, which is also known as ASRTU-1. Uplink frequency is 145.850 MHz, with a CTCSS tone of 67 Hz, the same as that of SO-50. Downlink is on 435.400 MHz. As, usual, I had kept my Moxon Yagi in the direction of maximum elevation of the pass. Though I did not expect anything from the satellite, I was surprised to hear E21EJC from Thailand, at a distance of around 2700 km. I gave a call and quickly got my report. I never expected to have a DX contact as my first contact on AO-123!
