MY question is as follows, I purchased a new SD card from eBay recently, I installed it and seems to work.. my only issue is when I went to systems and input Lompoc federal (FCI) Prison , it will show the channel/frequency when there transmitting, but no audio.. I can still put the other SD card I had back in, and works fine on this site (FCI) Lompoc prison.. so new updated SD card isn't allowing this site to fully function like it should.. any ideas why ? Thanks ..
