Hi all new to this forum and have been reading a few in the last 2 weeks. I have put up a 5 LNB Slimline not a SWM dish. I get good readings on 101, and 119 and on 72.5 (don't know where that one is comming from). But any way I get nothing on 99, and 103? I'm using a Birdog USB 3.0 meter is there a reason for this? Or am I doing something wrong?
