The Grandson of Zerobeat Right Angle is an update of the Grandson of Zerobeat kit
which has a right angle daughter board for the LEDs in either 3mm or 5mm LEDs or the HP LED array
Grandson of Zerobeat Right Angle has 9 LEDs which graphically indicate the frequency of a received CW audio tone. Adjust your transceiver's
frequency until the green LED lights up and you are within +/- 10 Hz of zero beat with the transmitting station.
