Welcome to my Blog. For
beginning i will describe the building of a Qrp transceiver.
A lot of units are ready
and i will present them with some corrections. The heart by transceiver is two
microcontrollers (PIC 18F4520 and PIC 16F877a). They control everything (BPF,
LPF, Preamplifier, Attenuator, Volt, Amp, Temp, DDS VFO ...). The Mic is one
Kenwood MC-44 and controls the two VFO the UP and Down and the memories.
You can do any
observations about this project. It will be my pleasure to hear your opinion.
My time is limited but i will do my best.
If you want to
experiment yourselves use any circuits or combine them with your favorite
circuit.
One other project that
you can find is a HF Beacon on 10m. The project is not finished, I have to
experiment with the input and output impedance, of the driver and final
amp.
I want to thanks all
QRPers for the ideas that i have included to my Projects.
