Hello guys just a real quick question... I have a 510 and a 301 rcvr... I have lost most of the channels coming off 119 yet I am getting very good signal readings... It has been very hot here in northern IL the past few days so I am wondering if it is a LNBF issue or could it be a bad switch??? It just started happening around Noon CDT so I am thinking something may have gave up the ghost... Any advice or suggestions?????? CC
