Simple 6Meter kilowatt amplifier Circuit Diagram

This is the Simple 6Meter kilowatt amplifier Circuit Diagram.The amplifier uses a grounded grid circuit with either the Eimac 3CX1000A7 or 8877, ceramic/metal triodes intended for linear service in the HF and VHF ranges. The amp provides the legal power output of 1500 watts PEP and CW service with no effort and requires a driver delivering between 50 and 80 watts at 50 MHz. With a plate voltage of 3000 volts at 0.8 amps the amplifier performs at 60 percent efficiency. The grid is grounded by means of the grid ring of the 3CX1000A7 socket providing a low-inductance path td ground. The amplifier is completely stable.

Making PC USB LCD controller project

This really a work that so cool if you like modif PC. So this is a USB interface for alphanumeric LCD display like 4 × 20 which can be controlled with LCD Smartie program. USB interface is implemented by using PIC18F2550 microcontroller, Using USB LCD modules. Below is a project of the USB LCD controller. Schematic circuit and PCB design source | link
