i have a two fold problem with my carrier current am. it so far does not appear to interfering with any electronics outside my household but it is interfering with two peices of equipment in here.
1) i have a baseband NTSC security camera system that the AM is putting RF interference patterns across the cameras
2) it jams out 850 khz on my TFT EAS 930 AM Receiver.
it does not appear to intefere with other radios just the card in the EAS 930. probably poor design on the Rx Card.
i think i need 3 fold solution. i need a low pass filter for am broadcast in addition to an 850khz reject filter on the Tx and a 1630 reject filter on the Rx deck.
the Tx filters would need to handle up to 5 watts average power.
i need some basic designs for said filters.
since carrier current is largely not used anymore there is not any info on the web (that i can locate) for such designs.
