In this blog I will describe the designing and building of a HF (QRP) transceiver.
I have already build one some years ago. Now I will try to build a better one.

Next picture shows the old one.

 Some of the features:
-Triple loop pll synthesizer,. 30 Hz steps.
-Controlled by micro controller pic16F84.
-Covers 500 KHz on 80 40 30 20 17 15 12 and 28 MHz.
-Modes usb, lsb, cw
-CW audio filter.
-Power output 8 Watt PEP on 80 meter, 3 Watt  PEP on 10 meter. Power is adjustable.
-AGC 1 speed.
-CW side tone

The new one should have extra features like.
-5 Watt PEP on all bands.
-Coverage of all HF bands including 160 meter.
-Adjustable IF Width.
-RIT.
-Noise blanker for pulse noise.
-Internal power supply.
-AGC different for CW and SSB.
