The Digital Dial is primarily intended to be used as a simple means of adding a digital frequency read out to single band QRP radios. A programmable IF offset feature allows the counter to measure the VFO frequency but display the actual operating frequency. The digital dial can also be used as a general purpose frequency counter. It also includes a special “crystal matching” mode, which allows the matching of crystals used in IF filters to with in 10 Hz of each other. Frequency range: 100 kHz to 45 MHz Resolution: 100 Hz displayed, 50 Hz internal Update rate: 200 ms Input level: 50 mv to 100 mv p-p min, 2 V p-p max. (sensitivity varies with freq) Input impedance: 1 Meg ohm. Display, four digit LED Supply voltage: 8 V min, 14 V max Supply current: 37 ma, typical Size: 2.1” wide, 1.1” high, 0.5” deep
