  • Notes
  • This is a variant of the less-expensive Dual-scale 205A. The quad-scale unit has full-scale ranges of 1.25, 2.50, 12.5 and 25.0 peak kHz modulation. In addition to having all Dual-scale features, this model is ideal for selective-calling systems employing tones as low as 50 Hz and modulation as low as 0.75kHz. Both models feature direct-reading of modulation in peak kHz - no charts or tables. Tuning is continuous from 25 MHz to 500 MHz - no switching or coil-changing. Modulation accuracy is better than 10 percent of full-scale.
