Thanks again, Bob, KN4HH

Tons of noise on the floor of an Invader 2000 in SSB
This is a question regarding the Johnson transmitters sensitivity to hum, etc on the mic input.
The background:
I've got an excellent Invader 2000 that I've used mostly for CW. It's got a clean (well, for the period) CW note with a couple of close in 60 Hz multple spurs but they are about -40 dBc and there's nothing above beyond 180 Hz.? Otherwise a lovely CW signal.
But with some of the QSO party's ongoing, I hooked up a mic and worked a few guys over the weekend.? And a few of the guys mentioned I had tons of noise on the signal.? In checking it on the audio spectrum analyzer, it looks like it's got 60 Hz multiples all the way across the audio spectrum.
I'm actually not surprised that there would be **SOME** 60 Hz and harmonics present.? In my setup, the D104 has a W9AC JFET buffer driver in the base.? The buffer has an output Z of about 150 ohms.? That output feeds through shielded cable up to a relay box where the mic cable is routed onward (via shielded cable) to one of 4 transmitters.
If I hook a D104 (no buffer) up directly to the Invader, the signal is not too bad with noise down about -40 dB or so.? Not great but acceptable.? And if I turn the mic gain to zero, the noise drops to nothing.? So clearly the rig connected to a stand-alone mic works "OK."
But with the mic fed via the switching box, the noise is only -20 to -30 dB down - really lousy.? And here's the funny part.? The same switching system also drives a Hallicrafters HT-32A and a Drake T4XC.? Both the Hali and the Drake have noise floors (mic keyed, no talking) of about -50 dB to -60 dB down.? Better in fact that the Invader with the mic directly connected.
So this makes me wonder if there's something about the Invader that makes it somewhat more susceptible to these 60 Hz environment noise and in the setup using the switching system, it's somehow generating tons of harmonics.? Clearly given the Hali and Drake love the system, I can't say that there is a fundamental issue with the mic relay setup specifically.
One other bit of info.? If I disconnect the mic cable at the switching box end, the invader shows no noise.? But when I hook it up, and float or ground the mic wire at the switching end, the noise remains.? Literally no change with the mic wire either way.
There seems to be something about this connection to the switching box that drives the Invader nuts specifically.? But does not bother the Hali or the Drake at all.
Appreciate any comments anyone may have.? I'm not a SSB guy so these mic topics are pretty foreign to me and I don't have any practical experience to draw upon here unfortunately.
Thanks!

Re: Wanted to purchase OR Loan
Don't have the meter, but have had great success reproducing meter faces using the Meter software.? You can create custom scales and it also handles the graphics.? It's from Tonne Software and here's a link to their website:
