Ranger 2970N2

[Metalball]

Hello all, just got a new 2970N2 so I need to pick a few brains!

Anyone know what's involved in moving the amp unit from bottom to top?

It seems to be a good mod in keeping with the laws of physics, but details of how to actually do it are vague, the 2970N2 is a new adventure for me!

Thanks in anticipation.

Thanking you for all the numerous heads up!

Jumped in the deep end today, and it seemed to me turning the amp upside down wouldn't work!
What seemed obvious to me that turning the front panel upside down was the way to proceed.

So, I started by removing the front fascia, clipping off the cable ties and removed the inner plate retaining screws.
I removed the PCB connector that runs to the mic socket as it's a little short if anything, then reversed the plate only to find two little connectors at the front of the PCB were preventing the plate from slotting into in place. I unsoldered the connectors, cut the wires and attached them to the solder side of the PCB, problem solved.
After fitting the front fascia and controls I replaced the lead that ran from the mic socket then tidied up loose leads with cable ties.

I took the opportunity to adjust PEP to 200w and AM to 50w and I'm well pleased with the results.

Love the one I have,talked all over the place on sideband,

Mount it upside down, quick and easy.......

I've seen where RadioHactive does that mod. I in no way endorse their work.

Beat me to it.

Why would you want to?

Better cooling while sitting on the desk. I thought about doing it to the one I had, but I'm lazy anymore.

Why would you want to?

because heat rises, and it also shortens the life of your equipment.
why take the components that can generate the most heat and stick them underneath all the other components?


I enjoy my ranger equipment, but

Instead of moving all components to the top, would another fan that pulls air out instead of intaking, say one on top wherever it can be mounted, work?? Seems like a lot of work to move all components to the topside? Maybe not? But a good brushless fan couldn't hurt could it?? I don't own a 2970 so I may be way off base here. Just thinking of other options that may be an easier solution per say. Sorry if I am of no help. But I do try. God bless.

I dunno, I had an N2 on base and I hung it on it's bracket. The fans pulled the heat out via the heat sink, and I never had a heat issue with that radio.

Mine was mounted similarly and got mighty warm. Output was within specs.

I'm guessing they figured it would be mounted under dash, and the heat sink unit would have more air exposure on the bottom than if it were on the top of the rig. Would be nice if it came from the factory with the ability to remote mount the head, or simply reverse it like my Kenwood V-71A.
