A few months ago, when we were recording episode 7 of the podcast, one of my two microphones started generating a noticeable electronic humming. We were able to get it to go away by grounding the mic (I had to touch it the whole time we recorded), and then during episode 8 and 9 I did the same thing to silence the hum. Unfortunately, when we tried to record episode 10 last Monday, I couldn't get the hum to stop.
I've got a replacement mic on its way, but it's not here yet, so we're unable to record a new episode until it arrives. It should be here tomorrow, so hopefully we'll have a new episode out early next week.
