Short towers are better for DXing. Not good for distance -- on a regular coverage area basis. The short tower provides a high angle signal -- that bounces and bounces. High powered clear channel stations must use the taller halfwave tower to provent the high angle signal from returning to close to the normal cocerage area provided by the ground signal --- and causing interference. KFI is only using 25 KW at this time -- with a shorter tower --- . The ground signal and skywave are NOT strong enough to cover the normal coverage area near Astoria, Oregon -- and yet the shorter tower is causing the 640 signal to Skip and Skip farther -- . The FCC needs to allow the remaining BIG 50 KW stations to move out of the metro areas -- and use taller towers. Change the City of License rules to allow the Clear Channel stations to serve the entire "Metro" area -- not one city. Allowing use of not only half-wave but 5/8ths wave towers would provide stronger groundwave and less skywave. Normal coverage would be more controlled - uniform. Just my two cents. _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca
