Re: ubitx schematic cleanup #ubitx

The QRPlabs 10W PA kit is not a bolt-on solution for the uBitx.
I don't think anybody has posted how to use this with a uBitx.
But doing so would be considerably easier than addressing all the issues
with the uBitx PA if you are going after a flat response from 3 to 30 mhz.

Swapping to the RD15HV FET's on the uBitx might improve power out
on the upper bands some, but hardly seems worth the trouble.

A better bet might be to buy the excellent PA kit from QRP labs:
Can give a flat 26dB gain from 3 to 30 mhz, 10W out, roughly 200 ohms in and 50 ohms out.
Note that it uses the $0.50 IRF510's.
