This is a 0~55MHz DDS Signal Generator. It is based on AD9850 chip and is very easy to operate.

Supports 0~55MHz continual adjust at 1Hz step.

Input 12V (Seller's Note: We are also providing a simplified version, with input 8~9V)

With direct digital input frequency

With audio volume potentiometer

With amp. gain potentiometer

With AGC potentiometer

S-LED display

Standing Wave-LED display

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:

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.

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).

Frequency display:

RX = MULTIPLIER x (RX_DDS_FREQ + OFFSET_FREQ)

TX = MULTIPLIER x (RX_DDS_FREQ + OFFSET_FREQ + TX_OFFSET_FREQ)

The frequency programmed into the DDS, is calculated as shown below.

RX = ABS(RX_DDS_FREQ)

TX = ABS(RX_DDS_FREQ + TX_OFFSET_FREQ)

RX_DDS_FREQ, MIN_RX_DDS_FREQ, MAX_RX_DDS_FREQ, TX_OFFSET_FREQ & OFFSET_FREQ

Examples:

1. DDS output range 30~40MHz:

MIN_RX_DDS_FREQ MAX_RX_DDS_FREQ OFFSET_FREQ RX Frequency display range.

30 MHZ 40 MHz 100 MHz = 130 MHz to 140 MHz. Note 1

30 MHZ 40 MHz -10 MHz = 20 MHz to 30 MHz. /

-40 MHZ -30 MHz 170 MHz = 140 MHz to 130 MHz. Note 2

-40 MHZ -30 MHz 60 MHz = 30 MHz to 20 MHz. /

2. Setting FT180A with DDS:

ENABLE RPT NO

X6 RECLK X6

DDS SYSTEM CLK 180M

MAX DDS FREQ 65M

MIN RX DDS FREQ 10.701M (Offset frequency + RIT frequency)

MAX RX DDS FREQ 60M

TX OFFSET FREQ 0

MAX RIT OFFSET 1K (RIT frequency)

OFFSET FREQ - 10.700M - (Offset frequency)
