LAB REPORT: MICROMEGAFM-10 (￡698)

摘要

Right at the outset, I am bound to say that if you live in a poor reception area or are relying on a T-wire indoor aerial then the FM-10 is unlikely to give of its best. I tested two samples by way of confirmation and if these are illustrative of the design then it appears the FM-10 requires a full 42dBuV to fully break out of muting, making it about 10x less sensitive than the typical' modern FM tuner. Our second sample had a more gradual muting characteristic and offered a useable S/N ratio at lower RF levels (~36dB for 25dBuV).
