Ok, trying to finally get up to speed on these new mosfets. I know there are IRF520's, and then I have seen 2030's or something like that. How do they compare to the 1969 and 2312? Which ones are in newer cb radio's now like Cobra,Uniden, and Galaxy? I also heard that the 2030 is more of a replacement then an up-grade in terms of power. Someone give me the lowdown.
