Ermi,
You raise an interesting point about the frequency of the test tone but I follow it only to a point. As executed, my test was sensitive up to the sixth harmonic of the tone (4800 Hz). This was done to include a reasonable number of harmonics, if present, in the passband of the receivers. Raising the frequency would include fewer harmonics.
A better detector would be beneficial but is not being sought at present.
