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.
