A problem cropped up with my cheap but otherwise quite reliable G2 wireless lav. The SK100 TX now seems to have a problem with the mic input. I've taken the whole thing apart and there's some corrosion on the plug contacts but nothing excessive.
What's strange is that when I plug in a lav (and I just bought an OST 801 with the locking TRS plug that arrived today to test this) while the TX and RX are tuned in, I get noise over the link to the RX, but no mic signal. No amount of fussing with SENSIT on the TX or AF OUT on the RX has availed me anything other than a slight buzzing noise, but usually just this hiss of the noise floor (headphones are turned way too high right now).
Ideas? Or is it just time to go to the WTB forum?
