RECEPTION REPORTS

You do not have to be a member of this group to send us a reception report.

Reception reports are welcome for ANY 600-meter station - not just WD2XSH stations. Multiple reports on the same station on different dates and times are encouraged as they allow us to see that communication is repeatable

The entire Amateur Radio community stands to benefit from your assistance!
