Breaking the 100kms barrier on 500kHz QRPp?

500kHz is proving quite a challenge at the moment: before I modify my set-up in a few weeks' time to increase my ERP ( less than 1mW currently) I want to get a few reports from greater than 100kms away. This target seems elusive so far, with the best DX remaining at 69kms, some 31kms short of my target.

The picture shows the longest paths my signals have spanned so far.
