Ironically one of the hardest to hear was the closest. MI0GRG is only 30 odd miles away and he was really hard to pull out of the mush.
DN2UDX was sending slow morse, and his call is a training thing.... but his separation of dots & dashes made it really easy to copy, and I told him so. compared to a station I QSOed yesterday who also sent slow, but blurry and SOOOOOOO hard to read!
another interesting one is DL4NCO . He has arthritis in his hands so cant work a regular morse key. he sends with a breath operated key which he invented himself. very clever!
