> This kit won¡¯t make the spur and bandpass problems of the uBITx go away.? Period.? Those problems occur in the early stages of the uBITx.? To the contrary it has the opportunity to make them worse since the gain of the amp is flat from 3-20 MHz? It may, however be a nice replacement for the final two stages in the uBITx if you want to maintain a fairly flat gain in those two stages.? That¡¯s all.
