First off, I need to know if you put the auxillary Low Pass Filter on your SAVXO before using it directly on the air? There is a document that I did a while back addressing that issue. I've attached it to this email, but not sure it will make it through. If not, you are radiating numerous harmonics and running an illegal transmitter. Also, my guess is that the 1-watt power lever you are seeing is very bogus; the SAVXO barefoot only puts out about 200 milliwatts, if I remember correctly.
I don't think there is an issue with the MagicBox either. Above 30 MHz, the power output falls off rather dramatically, and in fact is down a few dB at 30 MHz, but that was the best I could do with the components available. My guess is that the MagicBox is filtering out some of the harmonics and you are not seeing their contribution to the overall power you see when that device is not in the chain.
