I finally replaced my Lowrance with a Samsung tablet for ADSB In and Out using echoUAT, Avare, Garmin GTX 327, CMAX serial to Bluetooth, sniffing, wifi, Dynon 100, 180 & AP74.
I preferred a method which enabled me to remove the tablet after each flight for charging and update. Here's a pic.
Second, I prepared a WORD narrative during the gradual installation of ADSB. I am not an EE so lots of the jargon was foreign to me. As each step was accomplished, and as my understanding of the components improved, I constantly rewrote the narrative. Anyone with the same equipment who would like a copy of my narrative, PM me and I will send it out.
