Features: 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. 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.

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). 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 STEP key. Press CAL then quickly release to enter step F. F: CW_OFFSET: Fine tuning for CW working mode.

Satellite Signal Finder Meter Tester WITH 22K AND HORIZONTAL AND VERTICAL LIGHTS     This is exactly what the novice needs to align any satellite dish for optimum reception. Can be used for digital and analogue reception. This meter can save you a fortune in call out charges from satellite installers! Once you get the hang of using this you will wonder why you never gave it a go before!   Here is some more back ground information and technical details of what you do with this meter when you get it. Optimal alignment of a satellite dish is essential for trouble free reception. Movement of only a few millimeters can have a drastic effect on the signal strength and you will be rewarded with the message "no satellite signal present" on your television screen. A satellite dish has two main alignment adjustments, the azimuth which is the left to right or east to west position. The other adjustment is the elevation which is the up and down tilt of the dish. Using a compass you can set the azimuth to the correct value, for example 28.2 degrees east of south for Astra 2D which is the Sky / Freesat satellite. The elevation is then adjusted to the correct value using the scale on the dish bracket if it has one. If there is no scale or you have no compass then you can copy another satellite dish close by or simply use trial and error. If you initially set the azimuth correctly using a compass then the elevation is an easy adjustment. Failure to set the azimuth correctly will cause you to align the dish on the wrong satellite.   Description: Input Frequency: 950 MHz - 2150 MHz Sensitivity: 7dB Internal 22 Khz indicator light Compatible with DirecTV, Dish Network, and Free-to-Air satellite Systems Audio tone plus analog signal strength meter display Illuminated meter display for use at night Light weight and pocket size Allows you to setup or maximize your satellite signal reception at the dish by yourself without having a friend assist or having to make multiple trips to your roof Ease of use. Handy tool to align any satellite dish in minutes No external power or batteries required. Power supplied from your satellite receiver Extremely sensitive meter that indicates very small changes in signal strength   Package Included: 1 x Satellite Finder
