Can the RD16HHF1 be used as a drop in replacement for the 510 or will these mods have to be made? Just looking to get my uBitx back on the air. Seems like a good idea to place these in the finals to get ready to make the mods, or would you recommend replacing the 510s and then do the mods all at once?
