Just wondering if there's any directional anomalies with the orientation

So far I haven't been able to detect any, seems fairly omni-directional.

Hi OM,

Directional anomalies, as you put it, with asymmetric counterpoises
are academic at best. For FM, you would have to be well below levels
of full quieting before you noticed it (the partial dB anomaly); or in
your case of SSB (vertical?), by definition (and certainly practice)
you couldn't possibly hear less than the dB shift (for one, you would
have no basis of comparison as you would have no way of shifting it
in/out to discover the anomaly).

And on the third hand, the academic anomaly in all likelihood is in a
direction that is wholly outside of your normal propagation usage.

This can be cobbled up with the free version of EZNEC to confirm or
negate.
