Bob,
As Phillip recommended, check your transmit settings.
That being said, at 44 miles you are quite a ways out for our repeater and there is a fair amount of dirt in the way.
An analysis of the link says you will have about a 17 dB fade margin, which isn’t a lot.
Below you can see the path info:
Please let us know if we can help.
