Having run the 137.5kHz transverter with WSPR-15 (15 minute on periods) overnight - around 30uW from the earth-electrode antenna - I wasn't too hopeful about my chances with WSPR-2 this morning. WSPR-15 failed because of the thermal drift in the 15 minute on period I think.
Anyway I put the TX on WSPR-2 on 137.5khz this morning and let it run. After a couple of hours with no success I was VERY pleased to see I had been spotted several times by G8HUH at 250km. My previous record a year or so ago was just 148km (G3YXM) so this is considerably further and entirely in line with my predictions based on the QRSS3 beacon results.
