Unwanted signal on FM from a local station
Posted: Thu Apr 18, 2019 12:51 pm
Hi there !
Help needed !
On 88.1, I clearly get a "ghost signal" from a 100W transmitter, located about 1km from home (actual frequency : 103.9).
Of course, I lowered the RF gain : No effect (no effect means : either I still hear the unwanted station or nothing at all)
I set the IF AGC to manual and tried to set it properly : no effect
I switched from LIF to ZIF : no effect
I tried to move this annoying ghost station to differents places, from the left to the right of the spectrum window, to avoid possible non-linearity issue due to to other loud station within the waterfall selection (this sometimes helps) : no effect
NOTE : using my other SDR (HF+), no such trouble : the 'true' station on 88.1 is weak but perfectly readable running basic / defaults settings.
Is there something else I could try using SDRuno parameters / tools ?
Thanks a lot.
