Equinox and Etrac (Emi tests)

[tnsharpshooter]

What about Nox and Etrac.
How do they play together.

Detectors are around 4ft apart formthe testing below.
Etrac ran at 27 Manual sens and Nox at 24 sensitivity.
6 inch coils on both units.

When i use the term unusable below, I am saying audio on one or both detectors imo based on what I hear, detector deemed unusable at the approx proximity of 4 ft. More distance between could cure some of the affects maybe.

Now, here all I did was listen to Equinox wearing wireles headphones and etrac’s external speaker mainly to note any conflicts.
And there are some it seems.

I’ll check all modes and freqs on. Ox and post here.
Here is a start.

Channel 1 selected on Etrac

Multi freq using using Nox every detect mode checked with Etrac at channel 1 manually selected. Nox channel -4 unusable, Nox tied up in knots.
So it seems the same freq is used in each detect mode per channel maybe.
Also while in park 1, both 5khz and 15 kHz and 40khz single frequency on Equinox is in direct conflict it seems with Etrac channel 1, with Equinox At channel 8. Etrac unusable.

Park 2, Field 1and 2 checked all single freqs.
Same affects as noted above with park 1.

Other modes checked, same affects with freq selected and channel selected as noted above.

Now switch Etrac to channel 2.

Etrac unusable using multi frequency all detect modes while equinox in channels -9, -4, and 9.

Single freq 5khz channel 2 Equinox renders Etrac unusable.

A very detailed test, thank you for sharing!

To conclude the Emi testing I went back and spot checked to see how well noise cancel actually worked.
These spot checks I did see the same conflicts this morning as yesterday. I noise canceled with Equinox at less than 4ft from Etrac’s coil.

ALL spot checks passed (total of 10 noise cancels done with each )meaning doing noise cancel on Equinox 800 always went to a non conflicted channel, with Nox audio quiet. Etrac audio though after doing Nox noise cancel not always quiet. So Nox runners and Etrac runners may find each other doing mulitple noise cancels to find stable operations.

Here are the spot checks.
I geared most to running Equinox in multi frequency.

Channel 1 selected on Etrac
