WITH PLUG N PLAY CUSTOM CABLE. FOR FT-101, ALL TS-520s, TS820, OR TR4. SPECIFY WHICH CABLE YOU NEED. IT DOES NOT WORK WITH THE FT-101ZD. CABLE PLUGS INTO THE EXTERNAL VFO SOCKET SO YOU CAN’T USE BOTH. AN EXTERNAL VFO AND THIS DIGITAL READOUT. The unit has two operating controls, a BAND switch, and a MODE control. All of the VFO and band offset information for your transceiver is stored in the display’s memory. This allows the operating frequency to be displayed by counting only the VFO signal. Either 100Hz or 10Hz resolution is switch selectable. Each band can be individually calibrated to allow for crystals that have aged or any other error, to an accuracy of 10Hz. The calibration information is also stored in memory, so that any time you return to that band, the display is automatically calibrated. You only calibrate each band one time. The ESP DD-103 has a band that is always available for use as a bench counter. High accuracy and stability is achieved by the use of a TCXO refference oscillator. The DD-103 uses a backlighted LCD display and is 2″H X 6″W X 4D. The item “DIGITAL DIAL WITH FT-101 TS-520/TS-820 OR TR4 CUSTOM CABLE” is in sale since Wednesday, June 20, 2018.
