Ranger RCI-2950 vs Galaxy 99/Magnum S6

I recently bought a Ranger RCI 2950 (Orange screen, not the DX) from a guy at a truckstop with a built in Connex board and RK56 mic for $80. Seems to work great considering my poor antenna setup on my Volvo tractor.

I haven't been able to find any information on the old model, everyones advertising the revised DX model.

Could anyone point me in the right direction or tell me details on this radio and what it's expected output is?

I've got an older Galaxy 99 (Bought for $150 including RK56 mic.. gotta love Vegas!) I run in my Silverado pickup truck, and a Magnum S6 in my semi. I'm wondering how this radio compares to those above models.

Thanks in advance!
