I picked up a Sanken Cos-11D last week, and on my first shoot with it noticed a very weird problem. There is a strange repeating hiss every 20 frames on all of my interview audio. It's not really noticeable while the person is speaking, but during gaps or breaths it becomes much more noticeable. I didn't hear it at all during the shoot, so it's all over the dozen interviews we did this week...Thankfully I can remove the noise with Adobe Audition, but does anyone have an idea what would cause this? Here's an upload demonstrating the problem during quiet portions of the interviews, with white flashes to highlight where the sound occurs:

I used the mic with a Sony UWP-D16 wireless unit that I also just bought. I think I ruled out an issue with the wireless unit though - I used a boom with the plug on transmitter for b-roll audio on the same shoot, and I haven't heard any weird sounds on those clips. The receiver was plugged into the hot shoe on a rented FS7 and I routed the audio through the hot shoe. That's the entire reason I bought the Sony wireless unit, I needed a new wireless and have been doing a lot of FS7 work lately. Figured that feature would come in handy.
My final note about this - Since it's almost 2am and this has been driving me nuts, I just re-tested the mic. I don't have access to the FS7 right now, so I ran it through my Tascam-70D. I couldn't find any evidence of the sound during that test, so now I'm even more confused. If it was the FS7 causing the issue, why didn't it affect any of my other audio from the shoot? Anyone have any insight here?
