Thanks everyone for the response! I've implemented a lot of your suggestions and seem to have found a middle ground.
I changed my TX channel 1 to a more open frequency, swapped my Comtek cable for the manufacturers cable, and changed the Sony TX (hops) freq as far away from everything else as I could. My range has mostly returned to normal but I am still battling some issues with the Comtek's. They seem to work decent indoors but when running around outside every so often theres a terrible clicking sound that lasts 3-5 seconds sometimes. It's pretty loud and persistent and seems to overtake any audio being sent. Is there anyway to scan for more open channels on the Comtek M216 / PR216's? (I've attached an img of freq finder with my current frequencies)
Also I've ran into a different issue recently - whenever dialog gets close to or barely hits the limiter on the SD633 I get distortion (+14db hard knee). I feel like I shouldn't be getting distortion as the level's aren't super hot. Normally I shoot for 0db and +8db for peaks but it seems any louder than that will cause distortion(maybe talent will yell or cheer and hit roughly +16db) . It doesn't happen every time but often enough to look into it. I reviewed some files to see if the distortion is just from hitting my L/R too hard or if it's on the ISO tracks and it seems to be distorting on both. The distortion isn't super prominent, after reviewing the files you kind of have to be listening for it to notice. In hopes to isolate the source of problem, I cranked the 633 channel gain to hit the limiters very hard and I got the same distortion sound (trying to rule out the lav's being overloaded, TX turned up too high, and RX being turned up to high). The interesting thing is, I'm working on a home renovation show, and there's lots of hammers, power tools, etc.. The power tools or hammer transients never seem to cause distortion - they'll hit the limiter and be fine. It's only the talent's voice that will cause distortion. I've tried different thresholds for the limiters as well as hard and soft knee. In the end I just started shooting for 0db - +2-3 for my peaks and for mix L/R +8 for peaks and +10 for the limiter threshold hard knee (these levels are for dialog).
I'm using Sanken Cos-11, with SMQV's and Lectro 411a's.
Has anyone experienced this? Am I just recording too hot? I feel like in the past I've hit my L/R pretty hard and have never really heard distortion under normal circumstances.
We've been working in rainy or super humid conditions.
Thanks everyone!
