What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[swathdiver]

just ordered a new heated clock spring to go with my steering wheel. even though my 2013 tahoe is a ppv, im hoping there's a connector somewhere hidden down there that attaches to the new heated clock spring

Think you need a new harness for the column... 25807858/60296271

I would check with @Galante, he bought the parts but do not know if he's gotten around to it yet and he's taken a sabbatical from the forum.

I really need to "un-soccer mom" my ride a lot more.

Yosemite Sam mud flaps and a a couple of 102" CB Radio whip antennas should do it. Don't forget the KO2s!

I want to figure out how to add both a ham and a cb to the tahoe. The hard part is I refuse to drill into the roof for the antennas.

Rear hatch, up in the 3rd brake light area or behind the hood around the hinge? Have seen a few where it's mounted to the rear bumper step pad and one coming out the gap around a tail light.

That’s not a bad idea. Wonder how well that will work.

@swathdiver I found this. I need to study and research for the ham test so I actually understand this stuff. I know /why/ the pattern would be effected by the placement of antenna- and I know what decibels are and how the scale works, but I don’t understand in practice what effect the -2.whatever decibel of placing it on the trunk would have for signal strength or reception or whatever.

That's all Greek to me. In the 1980s, I placed the antennas on the center of the trunk lid and on my truck, they were on the mirrors. Our Cutlass had a K40 on a magnetic mount, my '79 had one of those 4' or 5' Firestiks mounted on the lid and snapped off too many entering underground parking garages!

I'll eventually put a Cobra CB in mine but it's way down on the list of things to do right now, even below the loud hailer.

From everything i read, all i need is the wheel and the new clock harness with heat. If theres no harness tucked away i would have to provide ground and power.

A lot of antennas need a flat surface below them to project the signal that is being transmitted properly in to the atmosphere. Kind of like a cone on a speaker. The chart you posted shows the effective loss of transmitting power (in dB) as compared to mounting it in the middle of the roof due to loss of a flat grounding plane.
I am by no means an expert but have looked into it a few times in my life.

Here is an article on it.

Did it shift rough as well. Mines shifting hard into second and third

Could be the fuel. Until you run that tank out, be sure the MAF is clean and all the harness connectors are clean and tight, particularly the MAF and throttle body ones.
