[BC] Overcrowding & noise floor on AM

[Rob Atkinson]

I got an idea of what clear channel radio used to be like recently.  There's 
a ham who transmits recorded ham bulletins from a location in Missouri on 
1860 KHz AM.  this guy runs 375 w. carrier to a 90 degree tower with 120 
radials.  every saturday he starts up at around 2 p.m. and signs off  around 
12 hours later.   Because no one else tries to use that frequency in north 
america while he's operating, the effect is similar to a clear channel.  
with only a 90 degree stick and 375 w. he's clearly receivable all over N. 
America.  Gave me an idea of what it used to be like to run 50 kw on a 
genuinely clear channel back when they were clear.  I think the guy's call 
sign is wa0rcr.
