Don, I also want to try AD9850's as VFO. The VFO seems to be stable, at least 0-30MHZ DDS VFO & Signal Gen Short Kit "A" (for AD9850 Module) Free UK Postage - EUR 27,09.
If you used a commercial source for artwork, pcboard, and install, can you provide info? Was the 9850 VFO a commerical kit? Can you provide details how to make pcboards at home that can accept AD9850's 40 thoughts on “ $40 Antenna Analyzer with Arduino and AD9850 I’m planning to build a DDS-based VFO in order to adapt an old crystal-controlled marine radiotelephone to the ham bands This little box of tricks plugs in to the crystal socket on the front panel of the WS62, switch the WS62 to Crystal and the "box" controls the frequency of the WS62 in 100 KHz/10 KHz/1 KHz/100 Hz/10 Hz steps. Arduino QRP Transceiver Meet my new rig - a QRP CW Transceiver for the lower HF bands, built around the Arduino "open-source electronics prototyping platform". Somewhere in the time period 2003/2004 an ingenious ham from India, Ashar Farhan VU2ESE, came up with a revolutionary concept. New PC VFO board DC to 54 MHz DDS. Si5351 simple VFO hardware setup I see that there is a need for a simple Si5351 sketch to get hams started using this great little cheap chip. The thread speaks to adding one to a 700 -- can anyone tell me exactly where (and how) the control voltage was added to the Swan VFO? I've already got the working X-Lock in the rig and picking up VFO output -- just need to know where to insert the varactor. The shield makes the DDS Module easy to configure ( through software ) and to control (through familiar, everyday interfaces such as Keypads, Displays and Remember, this is a 6 and 2 meter rig. AD7C DDS VFO. K who has very kindly granted me permission to publish pictures of his build DDS 4, he is also going to make the Bitx Vr 3 and hopefully very soon he would let us know as to how the Bitx 3 works with DDS Version 4. Readers have seen in recent posts how I developed a multi-mode beacon using the Arduino - but that was only a waypoint on the journey towards a full ham radio transceiver. You can make decent 0 -30 MHZ frequency Signal generator only in 12$ .
An Precession Signal generator is very easy and affordable make using an arduino and dds synthesizer (ad9850) . The kit contains all the parts to construct the VFO, a parts list comes with the kit, but the wiring schematic is in the Foundation book and was therefore not included in the kit, also you will need a 9v pp3 battery (or equivalent) and assembly tools. The DDS VFO (two choices), main rx/tx board, PA (several choices from 5W up) I've gone for 50W and output LPF again several choices. Arduino sketch for the Enhanced Kanga VFO. I love my old ten-tec Corsair II - its performance compares favourably with more modern radios, it's easy to service, and it has “real knobs” for nearly every function; but, arguably, one feature which lets it down is its Permeability Tuned Oscillator (PTO) VFO. This is a fully assembled and tested SSB Transceiver for $45 including shipping from India! Connecting the DDS Module to the Raspberry Pi to make a simple RF Signal Generator The DDS module used to generate the RF signal for the Raspberry Pi Wobbulator is based on the AD9850 frequency synthesizer chip and is available from a number of suppliers on eBay. My problem is getting the pcboard with pattern for the AD9850 and soldering the IC onto that board. Hi, Although it's possible to construct a digital dial using devices like the PIC and ATMEL MPUs and LCD displays, it's now quite simple to make one that includes an accurate drift free VFO that is flexible and capable for today's radios. Now this was a perfect SOTA location, I stayed on top overnight and used the flag pole to my right to support a 40m/20m dipole, you can see the fixture I connected to, the little ring clamp, as soon as the cable car stopped for the night out came the radio gear, it even snowed! K2 EXTERNAL VFO CONTROL. Evolution of 40 Meter CW Transceiver –Universal VFO –Suitable for R1 and its successor, the Mini-R2 This is more challenging with a valve VFO than a solid state oscillator. QRP 2000 USB Controlled Synthesiser Kit.
I have made three installations of the X-Lock in a HW-101, Corsair I, and a TR-7 so I know it works. First we present the video with the Bitx VFO that is connected with the Ik3OIL Freq counter. We have now received the new custom made MKARS cases, these have been made locally using the latest laser cutting and automatic bending equipment. Now I want to put similar VFO s for more specialised uses like (1) Antenna Analyser (2) SDR etc. Thanks to you it is working fine and of great use to me as a general purpose VFO. VU2ESE of BITX20 Fame has just introduced the BITX40. The National Semiconductor parts seem to work well. Ham Stuff. htm Here is a VFO stabilizer kit based on Huff and Puff Amateur Radio (G3TXQ) - Ten-Tec Corsair II PTO. 3V) makes it suitable for QRP, and it's cheap to build. After his design was tested by Gareth G4XAT and Steve G4FYF, they requested several changes which I carried out.
The local oscillator is stable DDS VFO and DDS BFO/Carriers oscillator. by Hans Summers. The MDT (Minimalist Double Sideband Transceiver) is an inexpensive and easy to build kit for the 40M band. ), an 80m SDR receiver and a Stockton power meter, G-QRP Regen Receiver. dxkits. 2. If you're using other displays, you must Pacific Antenna strives to offer the best quality, affordable, antennas and kits available in today's market and make your kit project a complete success. 1,8 - 30 MHz +50 MHz general coverage This new project uses my AD9 9912 DDS board ( 14 Bit 1GHz DDS) and the PIC panel used in several others my project Arduino is the popular open-source electronics prototyping platform based on easy-to-use hardware and software.
