When I opened my mailbox a few days ago, I had to do a double take. I received a QSL card that I was no longer anticipating! The Caribbean Beacon is a station in Anguilla that transmits the late Dr. Gene Scott's pre-recorded religious-oriented broadcasts.
This was a difficult QSL to get. First, the station does not broadcast any identifying information, it only identifies its content provider. (At least, that was my experience.) So I had to search on the web to try to find a mailing address. Then I posted that to the rec.radio.shortwave newsgroup asking for confirmation, and someone gave me a different mailing address. Then I went to several post offices to try to obtain an international reply coupon, which turned out to be impossible at the time. Then I mailed my letter off along with a U.S. dollar inside for return postage, and after almost 6 months, I assumed that my efforts had failed.
The postage stamp on my QSL card lists the postage value at $1.50. This is probably in East Caribbean Dollars (XCD). XCD$1.50 equals about USD$0.56 so my postage reimbursement was fine. IRCs currently cost USD$1.85 which would have been way too much.
The back of the QSL card includes an email address below the signature. If you'd like to get a QSL from this station, perhaps you can request it via email.
