To put those numbers in perspective: the QMX doesn't have the strong signal performance of a state of the art 2024 design, nor should we expect it to at its price point. Aside from the number for blocking gain compression, which is likely caused by AGC action rather than blocking in the front end, those numbers would have been respectable for a high end rig in 1994. They're still good enough to make using the QMX on the air a pleasant experience in anything but the busiest contest conditions,?and better than we'll see from most rigs that?cost under $1,000. The excellent numbers for transmit keying sidebands are also worthy of note, and the fast T/R turnaround means that it will work well for full QSK. The CW keying waveforms are also outstanding; no shortening of the first dit, and both of the dits on the scope trace are the correct length.
