I like the µBITX a lot. I should say that I like the concept of the µBITX a lot. It is a great concept to produce a decent super-het using fundamental building blocks and provides a great learning experience to those who take the time to examine the schematic. It's been fun modifying the radio. The receiver is actually pretty good.
The only downside is that the transmit power output is wildly variable based on the band. I have come to accept this as a function of the compromises made for a low price point. I did spend some time experimenting with exchanging the TX pre-amp transistors with more substantial 2N2222s but found that the upgrade was not really worth the effort. This may be due to possibly bad/fake transistors (watch what you buy on eBay)...
Its too bad that everything is on one board (again to keep costs down). If the receiver and transmitter exciter were on one board with the final TX amp and low pass filters on another, I could have easily used a different power amplifier (like the great QRP Labs 10w linear amp).
I learned a lot playing around with this radio. I may still take a hack saw to the board and chop off the amplifier...
