A-GPS-Locked-Frequency-Counter-Frequency-Standard-by-WA2FZW
This project is a GPS locked combination frequency counter/frequency standard.
A-Program-to-Calibrate-the-Si5351-by-WA2FZW
This little program will run on an ESP32 or an Arduino and can be used to set the correction factor to compensate for off frequency crystals on Si5351 modules.
Adjustable-RF-Attenuator-by-WA2FZW
A low power adjustable RF attenuator intended for such applications as being between an RF preamplifier and an SDR.
Amplifier-Preamplifier-Sequencer-by-WA2FZW
This device can be used to switch an antenna mounted low-noise preamplifier and a linear amplifier from receive mode to transmit mode (and vice-versa) before actually sending power to the antenna.
An-FT-891-CAT-Control-Emulator-Library-by-WA2FZW
This library provides a means of adding CAT (Computer Aided Transceiver) functionality to Arduino (or other microprocessor) based applications.

This document describes how to sync SDR Console with a transceiver using the DxLab Commander program
WA2FZW/The-JTDX-Fox-Hound-Dilemma---Solved
Some operators are of th opinion that JTDX is better than WSJT-X for FT8 operations, however, JTDX doesn't support the Fox & Hound mode used by many dxpeditions. This document describes a method of using both simultaneously.
