unsolved mysteries

 I forgot to look at the VE3DNL alone with the Tinysa, here is the result, 9V supply, 10 kHz output gimmicked to the TinySA whip:

Mystery 1: why are the even harmonics strong and the odds weak ?  Intuitively a square wave should be mostly odd harmonics.

Here is the VE3DNL hooked to the Pulser, then to the TinySA via gimmick:

Mystery 2: why is the signal stronger than the VE3DNL alone ?  Intuitively the even response would mean that the signal strength would be lower.

The mysteries are probably just setup/fixturing problems.  But still it's good to confirm that that the VE3DNL alone has uneven amplitudes on the harmonics.

Mystery 3: why not hook the TinySA to a computer instead of taking a picture of the screen ?  That one is hard to answer :)
