Thanks..Since it's a coax, there should not have been an increase in interference from a far field source, the gradients across the coax diameter aren't large enough to support differential excitation..
The fact that interference increased means the equipment isn't fully rejecting the common mode signal increase between the shield and the hot..the two concentric loops formed by the coax are feeding different impedances, that result is logical.
If the distortion had increased along with the interference, I would have guessed that the ground current was returning along the panel between the input and output jacks..and the loop was sensitive enough to present them..
I don't think the inner conductor resistance is in play, I still remember you talking about the contacts affecting the reading, I just can't seem to get away from that.
Can you rerun a cable, but include some honkin big shorting conductor from output shield to input shield, in an attempt to change the ground loop resistance??
I'll try to get a good picture of the st1700, along with something in the way of internal layout and schematic. That way, I'll be able to provide some more intelligent possibilities to test..
Have you done any correlation between physical parameters of the cables and the results of your test? I was thinking about cable capacitance, resistance, inductance..and, although this might be stretching it a bit, the dielectric type?
With all the DA talk, is it possible your rig is more susceptible to that than the AP?
JC...Thank you for being patient and taking the time to try these things..
Cheers, John
