Color: Red
Dimension: Approx. 176 * 60mm / 6.9 * 2.4inch
Package weight: 131g
Keys & Connection interfaces:
ENC: encoder switch
MEM: switch for memory mode
VFO: 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 frequency
CAL: Set functions
KB-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
