THIS supremely portable absorption-type instrument is directly calibrated in eight bands between 100 kc/s and 100 Mc/s. A primary use is harmonic identification in the case of transmitters having a crystal drive followed by harmonic multiplication. The wavemeter requires no power supply and may be easily held in one hand whilst adjustments are being made. The instrument itself, which measures only 5 in. x 3¼ in. x 3¼ in. over projections without tuning inductor, comprises a tuned circuit in which resonance is indicated by a sensitive moving-coil microammeter with crystal rectifier. It has an accuracy of 3%. For carrying purposes, a polished hardwood case accommodates the instrument and its eight plug-in coils.
