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|
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.
