Thanks for answers. The symetrix output impedance is 200 ohm and it is recommended to not load it lower then 600 ohms. I lifted the plus side of c20 and connected a 10k resistor to ground. I connected the signal from the symetrix output to the plus side of c20. This way the signal comes direct to ne602 and u3 is not involved.
The distortion is still the same and no difference what signallevel I put out from the symetrix. from a very low level until a 3 bars of alc reading. I am still listening to the Lf signal from the symetrix just to be shure it is no clipping from the unit. I know this is not the way to drive the k2 just trying to find a way to see if U3 is the problem. The microphone I drive the symetrix is a shure sm58 and I also use a icom hm12 that i put direct in to the K2. The first 6 years I used the Icom microphone then the last 8 years I used the symetrix and Shure sm58 that improved the audio. 73 Mike sm3xgm -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
