Shortwave broadcast stations typically change their schedule twice a year, summer (A) and winter (B). Currently it is winter schedule B17, until last Sunday in March when summer schedule A18 commences. Depending upon when you buy the WRTH, the schedules contained therein may be obsolete. However, updates are available on their website. If you have never had one, get a copy and see if you like it. It contains more than just SW as it also lists LW, MW, FM, and even TV. If nothing else, the receiver reviews, advertisements, etc. make interesting reading.
