Can also be used with the TS-520 using the DK-520 adapter kit.
Digital readout is available on the TS-520S by connecting the DG-5 readout. More than just the average readout circuit, this counter mixes the carrier, VFO, and heterodyne frequencies to give you your exact frequency.
Six digits display your operating frequency while you transmit and receive. Complete with DH (display hold) switch for frequency memory and 2 position intensity selector.
The DG-5 can also be used as a normal frequency counter up to 40 MHz at the touch of a switch.
