Garry:

Okay on all....I am using the W1VD e-probe set up here in Findlay, 
Ohio.  Since there is no directionality
associated with the probe, I suspect that Savannah was competing with 
EB58 and overpowering it.
I need to compare the Navtex schedule schedule for Savannah and Niton to 
see if that meshes.

It is nice to know that the sensitivity of the probe is there....and...I 
am not using the 20db amp at the
end of the coax.  The antenna is isolated from the IC-R75 receiver by a 
1:1 isolation transformer.

Tonight, I am setting up to look for SAQ at 1450 UTC...so, that is going 
to be interesting at 17.2 Khz.
Probably won't see much, but, we will give it a try.

Thanks for the interpretation.....73,

Tom N8TL
