Color: redDimension: Approx. 176 *60mm / 6.9 * 2.4inchPackage weight: 131gKeys  Connection interfaces:ENC: encoder switchMEM: switch for memory modeVFO: Transfer from VFO A to VFO B, or from VFO B to VFO A.SSB: Working mode change: circulate from USB, LSB, AM, CW, and on and on...RIT: Fine tuning to receiving frequencyCAL: Set functionsKB-1 and KB-2 have common shared pin, but is not GND.notes:1. DDS SYSTEM CLK: can use frequency tester to get 30MHz oscillator, multiply the tested value at 6, then put the multiplied value here. If using AD9851, make initial setting at 180000000.2. OFFSET FREQ: can be set as + or - . Rotate encoder switch to change value, press STEP key, then rotate encoder switch to adjust step. Minimum working frequency plus (+) offset frequency should be high than 0 (zero).Package List:1 x DDS Signal Generator
