I wanted to see if adding a RF amp to my V4 ubitx would improve reception and see if there were any downsides. I bought the Wideband Amplifier kit from KitsandParts to make this simple. I added the rf amp in the receive path before the mixer. I'm pleased with the increased sensitivity, intermod from other ham stations does not seem to be a problem, and the only issue was some intermod from some local 50KW broadcast stations. Adding a BCI filter in front of the amp solved that problem. My antenna is a end fed long wire for 40-10m. My next step is to add agc to this amp.
