KD1JV Digital Dial

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 within 10 Hz of each other.

  • Size: 2.1" wide, 1.1" high, 0.5" deep

Comparison of Digital Dials and Frequency Counters

Each kit was assembled and calibrated per the manufacturer's instructions.
The sensitivity of each assembled digital dial was measured using a calibrated HP 8640B RF Generator and verified with a HP 8660C.
The Chinese Ebay digital dial, sensitivity could not be measured with the equipment used so a pre-amp was added.
