73 DE SM7ZFB

 

 

Installed beacon with ATU.

 

The open wire feeder is the brown cables that goes from the ATU and then outside the window.

 

Some close-up pictures of the transmitter.

 


 

The pictue above shows the doubler and power amp stage in its compartment.

 


 

This picture shows the finished 100mW transmitter with the PIC10F206 Microcontroller attached.

The red wire that goes between the to compartments, is the the 9.049MHz signal from the oscillator.
