Did some testing with the IMD Meter in my garden near my HF antenna. Field strength was either zero or full scale. IMD was either 'no signal' or very, very good (-34).
I notice from reviews on eham.net that at least one other user had similar results. After discussions with the supplier, they concluded that the meter was working and that they were putting out a consistently good signal. Maybe I'm just too pessimistic.
Anyway, KK7UQ's website indicates that he is 'offline' for a while due to medical treatment, so I will pursue this via email when he gets back.
Now I need to decide what to do next: begin the major K1 build, or have some fun with the oscillator.
