Noise from powerful signals visible on other bands
Posted: Sun Jan 14, 2024 11:45 pm
Hi all,
When receiving around 5.8GHz, we notice noise corresponding to powerful signals from the 2.4GHz band. Eg if there's a 1ms 20MHz powerful signal around 2450MHz every 10ms, when monitoring 55MHz around 5800MHz, we'll see a jump in the noise floor for 1ms every 10ms.
Does that mean we must use always use a band pass filter? Is there anything else to do?
We have other SDRs like LimeSDR that do not have that issue.
Thanks
