yeh that was me trying to get more speed :D. I have since then backed it down to 80mhz. Our house is 3700 sqft total with 1000sqft garage as well. We have one in garage, 3 Upstairs 1900 sqft and 3 downstairs 1800sqft. Then we have 2 outside in backyard. Most are turned to low and some custom DBM 10 for example.
