Thanks everyone who replied. ?I don't use the electret mic I use an old turner super sidekick and I replaced the cap with 1000000 uf in series not parallel as stated on hfsigs and I got a good audio report so it was getting dc voltage in the audio circuit causing the muffling. ?All seems to be good now. ?The 200 watts bitx is back on the air.
