Getting shock through my D104m6b - unique setup

[dahdahdit]

Please don't judge me after reading about my set up.

I'm using an indoor antenna called a Workman b100 Saturn antenna.
My power supply is a pyramind 6 amp with 8 amp surge
My mic is a d104m6b power mic..Astatic.

I recently purchased a MFJ 929 automatic antenna tuner, so I could achieve a good SWR.
(Please no lectures on how to tune an antenna without an antenna matcher. Please no lectures on how there is still lost signal. I know that.)

I had been using a Maco 91 antenna tuner, and it worked so so.
But I wanted something easier, so I upgraded.

I connected the MFJ 929 as instructed by the manual.
A perfect match is now achieved.

BUT

One problem.

Now I'm receiving shocks through my d104me6b power mic when I transmit!

Without any wise guy remarks, or wise guy solutions..ie..get an outdoor antenna and tune it...
can someone explain what's going on with the shocks? Can someone suggest a way to remove them?


Also the MFJ 929 has a screw nut thing on the back that says ground.
Is that for me to run a ground wire from the antenna to the ground screw nut thing?

What you have is called "RF in the shack..." Because your antenna is "in the shack" everything will be "hot" with RF. One step to reduce this effect would be to make sure all your equipment is grounded to a single point ground. The transmitter, tuner, and any other equipment should be connected to a single point and then connected to your station ground. In addition this should be connected to your house electrical ground. It might also help if the antenna was connected to this ground as well. Make your ground connections as short as possible and don't use anything smaller than #12 wire.

+1 for WA0CBW's reply. Had that years ago with a D104 Silver Eagle and Cobra 2000GTL.. Beasty bit my fingers every time.. Once I grounded everything it went away..

Thanks
So how do I go about grounding things?

If I ran a wire from my antenna, radio,etc and connected that/those to the nut/screw thing on the back of the antenna tuner that says "ground", would that be an effective ground?

I'm trying to figure out what the ground nut/screw thing is for on the back of the antenna tuner.

There is also another terminal on the back of the antenna tuner for wire self-made antennas. I'm looking forward to having some fun with at.

Due to the design of the Workman antenna there is lots of RF on the outside of the coax and everything its connected to like the radio case and microphone, etc is hot like touching the actual antenna. Your coax and microphone may be radiating as much energy as the antenna.

Grounding as in connecting wire from a ground rod or house electrical box to the radio or antenna is not the best fix since its a crap shoot on how various lengths of ground wire will interact and have varying levels of success.

Instead try connecting two or more 9ft long wires to the metal base of the antenna or to the connector at the base of the antenna and run them away from the antenna in opposite directions. These 1/4 wavelength counterpoise wires will cancel out the RF on the coax and improve the performance of the antenna.
