Here are some pictures of my recent project, a very small SSB QRP transceiver (schematics can be found here) that covers the 20 meter band. First let’s have a look to the front panel:
And here we go for an inside view:
Starting on the left you can see the AD 9835 DDS chip on the very compact breakout board by artekit.
The breakout board is mounted on a 2 x 8 pin socket row to have the possibility to change the IC ver quickly in case of damage (I set all ICs into sockets without any exception). Above the DDS there is the ATMega 8 micro. Right from the rf-shield made of brass you can see the 9-MHz local oscillator with the ssb modulator and product detector IC NE 612.
For more information on board layout and part distribution have a cursory glance on this commented picture:
By the way: Had some nice contacts today with stations from all over Europe with 5 watts out. The rig is really fun! 🙂
