This card is from the one and only: Martin F. Jue, head of MFJ Enterprises. Martin writes, “Thanks for the QSO and QSL card. Hope FLU adds to your QSL collection.”
Now, a public service announcement: GET A FLU SHOT THIS YEAR!
I normally don’t include QSL card where the number substitutes for a letter, but here’s one from ND0C. This one has a further distinction. It’s my first QSL for a satellite contact!
