378-1880 kHz - 3 dB attenuation
526-1710 kHz - 9 dB attenuation

Reducing the circumference of the loop would give the KiwiSDR an easier time, however this would affect the Red Pitayas which can tolerate larger signal inputs. A compromise is therefore needed.
Further observations were made in the early morning of Sunday 17th December. A snapshot taken at 0610z of the 80m band shows a real improvement with the bandstop fitted. The improvement is so marked that continued retention of the AM bandstop is justified.
