Free Shipping Condition: New Location: China AD9850 0~55MHz DDS Signal Generator For HAM Radio VFO SSB RIT 6 Bands Description: Features: This is a 0~55MHz(latest version. Firmware updated in 2013) ... moreDDS Signal Generator. It is based on AD9850 chip and is very easy to operate. Supports 0~55MHz continual adjust at 1Hz step. This generator has 78L05 voltage regulate. Input current at 200MA. Input voltage 8-9V would be the ideal voltage. Input voltage of 12V can only be used for short time testing. Otherwise will cause heat to board. 5p/6p connect to encoder as per photo. 7p of the middle connects to digital matrix input. 14p(8V GND) is 8V power supply from main board. If powered by main board. DDS does not need independent power supply. 1~6 correspond to 6 frequency bands: 3.8，7，9，14，18 or 21，27 or 29) ISB. USB, CW are the three mode choices. DT is signal from main board 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. How to operate: Press CAL. Power on, then we enter setting screen. Let go/release CAL. A: ENABLE 6XREFCLE: setting chip clock mode. Adjust frequency encoding setting. AD9851 set to 6-multiply frequency, AD9850 set to 1multiply frequency. Press CAL then quickly release to enter next step B. B: DDS-SYSTEM-CLK: Chip working frequency setting. Use encoder switch to adjust value. Operate in accordance with STEP key. AD9851 set at oscillator 6-multiply channel. AD9850 set at actual output of 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 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 STEP key. Smaller than 60MHz would be OK) Pres
