Topband: Spurious transmissions on 1830 khz by CKTB (610 kHz), St. Catharines ON

[donroden at hiwaay.net]

If the AM signal is 3x wider than a normal AM, you can be assured that  
it's coming out of the transmitter and being tripled both in carrier  
and sidebands.

If it is a "mix" from another transmitter or internal to the receiver,  
it will be normal bandwidth.... not three times as wide as a typical  
AM transmitter.
