Julie,

I am still a newbie too, it'll happen. I use an iMic on an Macbook Pro with Fldigi software. It is very easy to use.

I do the Mic Btn OFF when the mic is still plugged in. I think if it is disconnected, the radio "turns off" that option.

That's how I first tried, per the Fred Cady book. It SHOULD work but … I gave up in frustration. I can send you the pages from his book that describe that process but it sounds like you know what to do. The USB approach is easier and better, supposedly, for noise isolation.

You got me on that one!

The Keyer/MIC level controls the TX on PSK ( I think). For reference, my phone (SSB) setting when using the mic is about 25. When doing PSK, I set the level to 4, quite a difference.

You set the TX to VOX, right?

Good luck and you'll get it figured out with the elmers that are here, they are a great bunch. I was SO frustrated, especially being on a MAC, but got it sorted out.
