I have everything for my show ready to go, but I can not for the life of me get my Kulp FM Transmitter to work. I have the plug in loaded, and configured to run on a frequency. I am not sure what GPIO setting I need to have, so I am assuming that may be the issue. I feel like I have gone through all of them and reset FPP, but it is still not working. Any advice on how to get that little bugger working before I give up and order a USB style transmitter?
