Hi Kevin! I use filters made by Jack Smith at http://www.cliftonlaboratories.com/current_products.htm.
Great filters at a reasonable price. 73 Lloyd - N9LB -----Original Message----- From: FlexRadio [mailto:flexradio-boun...@flex-radio.biz]On Behalf Of ke...@3950.net Sent: Wednesday, November 19, 2014 7:36 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] Better broadcast band and longwave reception Both the SDR-1000 and the Flex 5000 suffer from poor AM broadcast and longwave reception, with images of BC stations breaking through in many inappropriate places, especially below 1 MHz. I have been wondering what others have done to remedy this. I have considered 1) a preselector/antenna tuner to greatly narrow the spectrum bandwidth seen by the front end, using my existing inverted L antenna; 2) a tunable narrow loop antenna; or 3) an upconverter to tune longwave and AM broadcast at, say, 4 MHz. I wonder if anyone on the reflector has any wisdom to impart on this subject. Thanks, Kevin. _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz To opt out of the Reflector: http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz To opt out of the Reflector: http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz
