Investigated a problem where transmitting from the MGL VT-10 comm radio would cause the CHT and EGT temps displayed on the Dynon Skyview to increase by 10 or 20 degrees F. Installed a DB 25 plug capacitative filter at the inlet of the Dynon EMS-220 unit. Adding the filter eliminated all comm radio interference with the EGT/CHT display. The filter is L-Com part number DGFC25MF.
