VK0TH 7002kHz CW straight key

This morning heard very weak Trevor VK0TH  at 7002kHz  
No ID copied but it was clearly a straight key.
I did not try without clearly hearing the call.
And had to leave for QRL 
Hope to have an other chance but only a few more days left.
Few months back strong signals at 28MHz  WSPR from
