Stable vfo PDF results

Simple direct conversion receiver

We've had experience with this before, and have found the ne602 oscillator to be remarkably resilient, forgiving, and stable. naturally, to enhance vfo stability, we...

In this issue:

With most rigs using frequency synthesizers, dss, or frequency stabilizer schemes, the demand for a very stable vfo is almost mandatory or the receiver will not be...

An easy-to-build vfo

You can check to see if the setup is stable by turning off the vfo, but leaving the transmitter on. if you get output from the final stage then the rig is taking off on its...

A pic16f628 controlled "fll" (frequency locked loop) vfo for hf

The challenge, while developing this project, was to find out a way to arrange a very stable vfo with a very simple design, using very cheap and common components...

Building a direct digital synthesis oscillator

The project was intended mostly to demonstrate the feasibility of dds for homebrewers, and to provide a small, stable vfo for various qrp and similar...

High-precision permeability-tuned vfo, a

vfo a stable unit for receive. r or transmitter use. by walter horn, i1mk qst july 1964. the vxo can achieve frequency stability as great as that required...

Chapter 13 building a homebrew hf receiver

Modern receivers use integrated circuit frequency synthesizers to generate stable vfo signals anywhere they like. sometimes modern hf receivers escape from...

vfo stabilizer for the yaesu ft-707

This is the price i had to pay for a stable vfo. the huf puf pcb was made on a regular stripboard pcb (with longitudinal tracks). board lay-out:

Ssb transmitter for 80 meters (phase method)

Features

Sions of a clean stable vfo circuit that uses an analog devices adf4157 fractional n pll ic and an atmel attiny2313 microcontroller. one version is a 390 to 425...

A temperature- compensated dds vfo

Various frequency synthesis techniques can provide a low-drift alternative to the traditional analog vfo by using a more stable crystal oscillator as a reference...

Introduction:

Smooth and stable vfo: a special wide-spaced reduction drive capacitor glides slowly across the entire cw band (novice through extra). add the convenience of...

Obtaining vfo stability on the lg300

This arrangement has worked satisfactorily for nearly 20 years and enables stable qsos... 1980) amateur radio techniques (7th edilion) g3pdm high-srability fet vackar vfo...

Ftdx400 ssb transceiver, the history of yaesu "400"

-hybrid stable vfo allows us to read out 1 kc(not khz!) correctly.-am operation possible-there are no four slide switches at front face. some switchs at an outside...
