Re: uBitx v.4 build information



That v4 looks suspiciously like mine. You can search for Asshar's own words on c81, or tack solder something like 200 pF in parallel,  it might take an iteration but I was happy with the first cap I tried.

Given that the designer chose 470 pF to compensate the transmit chain, and since most v4 are fine as is, I think my suggestion to add a fraction of this value is rather credible. But if someone wants to try 0.01 uF, give it a try. Yes someone here did, and the higher bands  dropped a bunch.
