Also don't forget the baking pans!   8)
The Weber #6417 BBQ drip pan is a good choice as it is long enough to accommodate a Shure UR-2 HH mic or Sennheiser SKM-5200.

I was using baking tins which were not long enough for the mics for a while, which work fine if you put the antenna end in the tray, but I was finding that every time I left these in the care of A-2's, they would put the windscreen end in the tray, with all of the antennas sticking out, which totally defeats the purpose.

Thank you, Ike! I've had the same problems with standard sized baking tins and have been looking for a larger cost effective alternative for years. Up until now, all I could find were the pricey kind made from thicker, stamped aluminum with non-stick coating. No way I was going to spend $10+ per on 30 pieces of those!

Yer' welcome! The non-stick coating is definitely over-kill...unless you're having problems with baked-on microphones! ;)

We have a smaller cheaper version which I couldn't find on the website, but this one looks nice and big:

After two months of work and observation I can confirm the 'various intermodulation effects' diagnosis. Every time I have observed this phenomenon since my post I've had the transmitters extremely close to one other, the paddles, or both. I've not observed it once happening with transmitters in the field usually at least a body length away.

Thanks everyone.

Thanks for reporting back. These forums are a lot more valuable when folks do.
