Yes. Change R63 to 24 ohms. The earlier
rev boards had 100 ohms there, and V3 has 47. I put another 47 ohm
resistor in parallel with the one on the board. Now I don't need
to yell into the mic.

I have checked SSB output for the Ubitx using a Softrock sdr
receiver. The carrier is well aligned and the filter gives a
very good shape. Whistling is gives full output with the stock
mic element. The output seems clean but the average power during
normal speech seems to me a bit low. Is there an easy way to
increase it? 73, Franco
