I ?use series capacitors often, especially to avoid the transformer output shorting out the DC! 1 microfarad works usually

Hi all,?

i am about to connect my Raspberry Pi via a usb souncdard to the uBitx.

in relation to the mic out from the rig to the sound card - does the dc voltage present on the tip of the plug (for the electret mike) pose a problem? I am confused as to whether or not I should add a capacitor in line to block the dc? Should I, and would that even work?

thanks.
