Lightning protection installed / AM Bandstop / Second KiwiSDR

Protection from lightning discharge is an important consideration at a remote installation. This morning I installed an earthing rod and a Nagoya lightning arrestor near to the antenna feed point. No degradation in performance was noted.



A second KiwiSDR was installed onsite, for additional user capacity and side-by-side experimentation.

Currently, the second KiwiSDR has a newly purchased AM bandstop in circuit to determine its effectiveness. Currently, both KiwiSDRs have a 10 dB attenuator on their inputs to avoid constant ADC overload. I would like to find a way to remove these as this solution is not optimised. Users should be aware that this second KiwiSDR will be used for experiments and will have a lower quality of service.
