Re: Trouble with wireless micsRF devices tend to develop frequency drift over time. Cheaper gear is more susceptible to this problem. The SR40 system is a pretty low end piece of gear to start with. I wouldn't spend any time or money trying to get it serviced. Unload it on eBay or Craigslist and get a new system if it isn't working up to your requirements.
