Here's a video talking about the N2 function and showing the built in amplifier -

So it must be true of the claims that the IRF-520 device is good for 50 watts each. Hmmm. I see the heat sink issue to be part of the problem. That being said, I can see that they may change out the 'low profile' type heat sink and provide something with a little more meat on its bones - so to speak. Maybe a better heat sink compound would help too. I know a few locals that had bought the Magnum 257's - and then added a small computer fan to the heatsink - attaching it with drywall inserts. The RFX-75 may be able to produce 120 watts as some claim; but safer to run it no more than 75-80 watts. Ya gotta do - what ya gotta do...
I know a few people that use a Turner+3 on these radios with very nice results. They also adjusted the AMC on it as well.
Did you say that they fixed the white noise problem that it had?
You didn't say if the color of the LCD screen could be changed to another color?
Can the clarifier be unlocked?
Sparky's CB Shack does unlock the clarifier on his Rci-2950dx-2970n2
A pointless modification when the radio has a VFO.:bdh:

The design specification for the 8 mosfet exciter is 65 watts max deadkey on AM and swing max 200 watts. Why someone thinks they are smarter than the electrical engineers who designed the amp section is beyond any reasonable thought. Also there is a maximum duty cycle for using max power because the fan section stops running every time you key up the RCI. In the service manual they advise no more than 10 seconds at a time while tuning the transmitter at max power and test modulation. From this information, it would be wise not to key up at max 65 watts dead key and modulate at 100% for more than 10 seconds. In normal speaking rate average modulation will be far less. I certainly wouldn't play a 5 minute loud music piece over the transceiver at max power, much less scream into the mic for that long. So for normal use, I gather that the transceiver will last indefinitely if working normal speech at normal intervals at full power in room temperature. I've done this with the same amp section in another RCI radio and the transceiver gets warm but never hot.
The RCI is made to a tight high technology specification down to the last switch and knob, something you won't find in any export these days, including Galaxy, save for the common shared sections like the amp and echo board, etc with RCI. Used according to design spec, The RCI radios will outperform their competition in quality audio, stability, receiver quietness and sensitivity, and refinement in the human interface (knobs, buttons, etc.). RCI has the edge all around, its just that the users are demanding much more than the already stellar performance of the RCI radios. Overdoing something that already beats the competition is rediculous. You already have the absolute best in exports when you choose an RCI. To push the envelope further is like fighting a ghost, a non existing competitor. The challenge to push the radio further is best left with its designers and engineers and engineering techs that made this. Golden screwdriver types are doing something like putting nitrous on a McLaren F-1 ~ the refined design cannot accomodate this quasi detuning without breaking. The tolerances are high and should not be disturbed without thorough re-engineering. JMO
