Martin - I was only able to measure on 80 meters . My stock Orion yielded
an error of - 0.81 cycles or -0.20 ppm on 80 meters. ARRL sez in their
letter that anything within 0.5 ppm is probably within "doppler and other
propagation errors" .
I only gave ARRL the measurement to the nearest cycle as that was the only
significant digit I had with the 1 cycle DDS steps, unless I wanted to use
something external to the Orion.
Neat but not gaudy
