To what degree are AM broadcast stations required to suppress their third harmonics? The station in question is at 610 KHz, placing it's third harmonic at 1.830 MHz. It's loud enough to obscure weak
Hi, Jeff (K8ND), "To what degree are AM broadcast stations required to suppress their third harmonics? The station in question is at 610 KHz, placing it's third harmonic at 1.830 MHz. It's loud enoug
It is the braoacast transmitter manufacturer's and end-user's joint responsibility to correct any actual interference problems to either other BC services or NON-BROADCAST communications systems (thi
Jeff If the station on 610 is local, do a little "sniffing" nearby to your station to be sure that rectification is not the cause of the harmonic. For several years, I lived 1-1/2 miles from a 5kW st
Gary, I believe the 1830Khz harmonic to be pervasive throughout the northeast. Lately, I've regularly noticed a harmonic on 1832Khz as well . . In instances such as this, is there any chance our leag
Hi Jeff, The law is simple. 1.) They are not allowed to cause harmful interference no matter what level of spurious emissions are allowed in technical standards. This is a blanket rule that covers al
Down here in North Texas towards the North East at night on the 4 square is a very strong spur on 1830 Khz. It has been there for a little over one year. I looked over the local broadcast band but ca
Tom and all the rest: Thanks for the reply. It looks like we may have some ammunition in 73.44 if interference to 160 meters can be documented. The station is WTVN-AM on 610 KHz, located in the South
