Suddenly, right in the middle of Es season, the Dxworld.co propagation logger is not working.

It forwards to a site called "QTH.com", whose purpose eludes me.

That site had been indispensable for tracking Es activity in 6-Metre, 2-metre, TVDX and FMDX.
Would hate to go without it all summer 😣

QTH.com is a legit site...I've used their classified ads a bit. Dig around it the site and maybe you'll find the propagation logger.
