These are very nice pictures! And proffessional work! I've never done so, all my rigs are prototypes ;-)
It's also nice the see the stuff lying arround there. I see i'm not the only one :-)

Hi Graham, All,

 

I made an EER PA and Transverter to 3.5MHz for use on 500kHz based on Jim’s first design.

And I’m sure there are a few others about.

 

First prototype of Class D PA

https://dl.dropbox.com/u/15400416/IMGP0336.JPG

 

3.5MHz to 500kHz Transverter with Phase and Envelope outputs to PA

https://dl.dropbox.com/u/15400416/IMGP0371.JPG

 

Switchable 50 or 200W EER PA with automatic protection

https://dl.dropbox.com/u/15400416/IMGP0415.JPG

 

LPF and TX/RX Relay

https://dl.dropbox.com/u/15400416/IMGP0414.JPG

 

Final Trio

https://dl.dropbox.com/u/15400416/IMGP0385.JPG

 

Works a treat on all the usual modes and is even quite respectable on SSB.

90% efficient on full output.

 

Stefan’s attempt at a switched mode envelope supply sounds interesting, and a nice way to get mid power efficiency up.

 

73, Lee M0LMH.
