Hi. Okay I know I’m asking about two topics here but I’m wondering if both could be related to gain. My MLAT numbers they seem a bit low compared to others in the same area and would like to see improved numbers in general. The other issue is when some aircraft fly over they drop off the screen completely, typically helicopters though some planes too. Could both of these issues be related to a gain? Is there a particular app that people like that I can use for checking and adjusting check gain levels?
