When I am camping in the south of Spain through the winter, every sunday morning our 30m pskmail link to Sweden is covered up by splatter from french SSB stations. Pskmail makes use of the gaps in the conversation (there are weak and strong stations in the round) and delivers the information. The ARQ does this job by working around the qrm, not through it.
