Re: Ubitx average SSB output

iz oos All Messages By This Member #50338 I have changed just R63 so now it is 24 ohm (I added 2 ordinary 100ohms resistors in parallel) as suggested. I confirm it increases the average power to the right level given the stock mic element. Could it be further decreased, let's say 10 ohms? toggle quoted message Show quoted text Il 27/apr/2018 16:26, "Howard Fidel" <sonic1@...> ha scritto: 1K. Change one or the other, not both.

By the way the parts showed up here yesterday, thanks a lot. Now to find time to install them. Skip Davis, NC9O? On Apr 27, 2018, at 09:57, Howard Fidel <sonic1@...> wrote: 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.

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
