Compact 472Khz transverter finished

As I have some free time over the holiday period I have spent some time finishing off the G3XBM transverter. It's now placed inside the metal enclosure and all wired up.

 

Except for the layout nothing else has changed component wise and with 500mW input from the FT-817 it produces 18watts out, the transistor doesn't even get warm and the power doesn't even back down having run 5 WSPR transmission back to back? All the other versions I have built have produces 12-14watts!


Comparing it to my older version you can see a major differeance in size. Still deciding if I'm going to design a printed label for the front cover like the older one.
