Attenuator for the FT-817 by G4EFE

On my Blog post about the Power attenuator for the FT-817, that I published in SPRAT, I got a very nice comment from Martin G4EFE.

Hi Bert - I just built this into a tiny 25x25x50mm metal enclosure. Of course, it works great.
Looking forward to some QRPp WSPR from the IC703.

Attenuator built by Martin - G4EFE

As you can see, the attenuator is built in a beautiful, small enclosure.

Power

The maximum power of the attenuator is about 1.5 W. With a derating of 33% the nominal power of the attenuator is 500 mW. I advice to use the lowest power setting of the transceiver. For my FT-817 this is  500 mW.

Martin will use a IC703. This transceiver can make 100 mW at it lowest setting.

Thank you Martin for sharing the info and good luck in QRPp.
