"Perhaps some of the tech gurus here can dig a little deeper into the question of how a few hundred watts, or 1 kW, at 1820 can do so well, compared to MW signals at 1500-ish that need much higher power."
Bob, I'm no tech guru, but with top power in the 160 meter band being limited to 1500 W PEP, there's a lot less clutter on top band. In the 1500kc range, there's a gaggle of 5kW to 50kW stations lurking in the background 24 hours a day on the east coast. Furthermore, top band is primarily a CW band for DX which presents a very narrow bandwidth of transmitting and receiving frequency compared with a.m. Typical signal width for effective CW filters and transmissions is 500 Hz. 73 Gil NN4CW _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
