40 watt

I Just got a 40W Maxtrac 300 for my repeater It just wont transmit to my Repeaters frequency of 444.500MHz. It transmits for a sec and stops. It seems to transmit fine on 449.500. (Duhh, its in the bandsplit range) The bandsplit is 449-470 or somthing like that, and I want it to transmit out...
