8.495.3MHz CW "T" unidentified channel marker/beacon, possibly in Russia (Asiatic) 419-529 report from 1205-1213z. Not heard for quite some time due to poor propagation.
This beacon/marker seems to appear when band open to Eastern Asia, lends me to think the beacon is in Asiatic part of Russian Far East? Korea, Japan and southern China in around the same time with similar signal reports.
