Dear Members,
I'm Hiroki Ashida at Tokyo Tech (JQ1YCZ). As Mr.Hurst, Mr.Rupprecht and Mr.Henk have reported, our CW telemetry was changed. We're currently testing an amateur service function, "a digital repeater," so the message "hi hi de jq1ytc digi on" have been transmitted. I'm looking forwad to open our amateur service channel to you all!
And the APD sensor was turned on in the last pass over Japan and a long-term APD observation was started. APD status packet can be received all over the world until 12:00, Jun 11 (UTC). Your kind cooperation is greatly appreciated. If you received it, please let us know! -> cute1.7_receive@lss.mes.titech.ac.jp
