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

2. This generator has 78L05 voltage regulate. Input current at 200MA, input voltage 8-9V would be the ideal voltage.

3. Input voltage of 12V can only be used for short time testing, otherwise will cause heat to board.

4. 5p/6p connect to the encoder as per photo. 7p of the middle connects to digital matrix input. 14p (8V GND) is 8V power supply from main board.

5. If powered by mainboard, DDS does not need an independent power supply.

6. 1~6 correspond to 6 frequency bands: (3.8, 7, 9, 14, 18 or 21, 27 or 29).

7. ISB, USB, CW are the three mode choices.

8. DT is signal from mainboard.

Keys and 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 a common shared pin, but is not GND

Specifications:

Display: 1602 LCD

Input voltage: DC 8V-9V

Input current: 200mA

Frequency range: 0-55MHz

6 bands: 3.8, 7, 9, 14, 18 or 21, 27 or 29

Product size: approx. 80 * 45 * 30mm / 3.15 * 1.77 * 1.2inch

Net weight: approx. 66g / 2.32oz

Gross weight: approx. 69g/2.44oz

How to operate:

Press CAL, power on, then we enter the setting screen. Let go/release CAL.

A: ENABLE 6XREFCLE: setting chip clock mode, adjust frequency encoding setting. AD9851 set to a 6-multiply frequency, AD9850 set to 1multiply frequency. Press CAL then quickly release to enter the next step B.

B: DDS-SYSTEM-CLK: Chip working frequency setting. Use encoder switch to adjust the value. Operate in accordance with the STEP key. AD9851 set at oscillator 6-multiply channel, AD9850 set at the actual output of the oscillator. Press CAL then quickly release to enter step C.

C: MIN_RX_DDS_FREQ: Setting minimum working frequency. Use encoder switch to adjust value and in accordance with the STEP key. Press CAL then quickly release to enter step D.

D: MAX_RX_DDS_FREQ: Setting maximum working frequency. Use encoder switch to adjust value and in accordance with the STEP key. (Smaller than 60MHz would be OK ). Press CAL then quickly release to enter step E.

E: SSB_OFFSET: Fine-tuning for SSB working mode. Use encoder switch to adjust value and in accordance with the STEP key. Press CAL then quickly release to enter step F.

F: CW_OFFSET: Fine-tuning for CW working mode. Use encoder switch to adjust value and in accordance with the STEP key. Press CAL then quickly release to enter step G.

G: OFFSET_FREQ: Setting of offset Frequency. e.g, set to 9MHz or 10.7MHz, use encoder switch to adjust value and in accordance with STEP key. Press CAL then quickly release to enter step H.

H: MULTIPLIER: multiply setting for frequency. Should be set as 1, press CAL then quickly release to enter step I:

I: Screen displays word "SAVE", automatically save the above setting, and returns to normal working.

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 an 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. The minimum working frequency plus (+) offset frequency should be high than 0 (zero).
