John, You may have more than one problem here. First of all, it is clear that your speakers do not present a high impedance load. I have one set of cheap "amplified" speakers that will do the same thing when you turn up the volume. If you are using a single channel output like the Extigy, the TX and speaker audio paths are in parallel. By the way, the Delta 44 eliminates this potential problem by separating the speaker and TX drive signals.
Other than the speaker loading, this has to be some kind of setup issue because the calibration process confirms with certainty that the hardware is working properly. Make sure the line out cable is plugged in solidly on both ends. If it is not, you will loose 75% of your power. That would be about 25W output. You will also produce a DSB signal under that condition. 73, Gerald K5SDR > -----Original Message----- > From: John M.
