Iambic and Straight key amateur ham radio CW Morse code practice oscillators for Android. This Android app gives you both straight and iambic CW Morse code practice key oscillators. Each key translates Morse code into English and CW prosigns in real time as you practice. Practice sending Morse code with a straight key oscillator. Settings include WPM, show/hide Morse code/text, choose sidetone 400Hz-800Hz. Adjust the WPM so that you can produce well formed DITs and DAHs at a comfortable speed.

A versatile digital VFO design utilizing the Silicon Labs Si5351a oscillator chip and Nokia 5110/3310 graphics LCD display, operating from 1-160MHz with dual VFO capability. This microcontroller-based system, powered by an ATmega328 processor, features rotary encoder tuning, selectable step sizes, RIT control, and comprehensive band memory functions. Drawing less than 40mA at 3.3V, it significantly improves upon previous DDS designs' power consumption while offering advanced features like S-meter display, VFO lock, and programmable BFO/CIO offsets. The design achieves flexible functionality through simple hardware implementation and efficient software architecture, making it particularly suitable for QRP and portable amateur radio applications.
