SB QST @ ARL $ARLB060 ARLB060 W1AW to shift 160-meter transmission frequency ZCZC AG60 QST de W1AW ARRL Bulletin 60 ARLB060 From ARRL Headquarters Newington CT September 19, 2003 To all radio amateurs SB QST ARL ARLB060 ARLB060 W1AW to shift 160-meter transmission frequency Starting Monday, September 29, W1AW will shift its 160-meter code practice and bulletin transmission frequency from 1818 kHz to 1817.5 kHz, starting with the 4 PM EDT (2000 UTC) code practice run. The frequency shift not only brings W1AW's Top Band frequency in line with those the station uses on other bands, it also should help to eliminate possible interference from broadcast station harmonics and birdies--something that's more likely on an integer (ie, whole number) frequency. W1AW has been conducting code practice and bulletin transmissions on 1818 kHz since 1982. Prior to that, W1AW transmitted both CW and phone bulletins on 1835 kHz. NNNN /EX
