Awesome, it didn¡¯t hit me at first. I just grabbed two off eBay for $11 for both. I have parts I was going to use on interfaces, transformers, optocouplers, the easydigi has all you need. I¡¯ve known about easydigi for a while but now that I¡¯m digging deeper in EE I understand what all the parts do in the circuit. Even on antenna lines. The DC cap is very necessary when doing bias t on receive antennas. You guys taught me so much lol ;)

Joe Puma, yes that is most likely the purpose. ?Been there, done that, learned a thing.?

Gordon, I¡¯ve been using the easydigi¡¯s, is that the purpose of cap in between both mic and audio connections to radio?

Transformer Makes it worse. ?
Do not short the dc bias voltage¡ªlikely it will take input transistor or op amp to un-usable ?bias?

could something like a 600:600 transformer solve that issue too? I¡¯ve ?been putting them between all my audio and mic I/O¡¯s when connecting to pc/soundcard

We made the mistake of not dc blocking mic inputs of some commercial vhf rigs ¡ª-bad distortion in input stage?

Is dc blocking capacitor necessary between sound card audio output and mic input of ubitx during digital modes?. I made a direct connection between above without DC blocking cap. Though? my ubitx received so many, very few logged my
cq calls as per pskreporter. Any advices?
