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.
Notes: 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.
