I received the following question from a reader, "Do domestic stations issue QSLs anymore? When I was a kid they did."
Yes, they do, but probably at a diminished rate than in the past.
I had about a 50% success rate with AM radio stations way back when. Today, I don't know for sure because I have not sent a reception report in eons, but I expect that the success rate is poorer due to smaller staffs and automated stations.
The reader also asked, "To whom would I address the reception report?"
Address your reception report to the Chief Engineer of the radio station. Station addresses can be found at Radio-Locator.
Like I wrote above, I have not sought a QSL in a long time, but I think it is time to try again and experience QSLing in the 21st Century.
