1K. Change one or the other, not both.

If R63=24ohm what value should R65 be?

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
