WLW - 700 kHz, 500 kW, 100% modulation, no limiter

Most AM broadcasters utilize asymmetrical modulation where they often allow %115 positive peaks In case you missed it, the 500 KW was in the 1930s. 250 KW of audio was not easy to come by. Last I heard WLW was using a Harris 50 KW digital AM transmitter. See http://download.harris.com/app/publi...d.asp?fid=1489 .. Digital here means that the AM signal is digitally synthesized at high level. There is no modulator. Tam/WB2TT |
