Datalog Datalog Datalog!
It’s really easy and if you have any questions feel free to email me and I will guide you along. Get a laptop, a good wideband, and dedicate a little time to drive and record the data needed to determine if your dialed in or not. If you need help deciphering the data gathered shoot me an email!
Datalogging software for the most part is free online just do your homework.
