I have a Dwight D. Audio good, voltage at final. No trans. , no receive but a hiss in speaker as though it is receiving.
Any ideas as to what to check next?

First blush: unlocked PLL loop
If you have no receive audio and there is no change in the RX/TX LED when keying; then the first, logical choice is to check PLL lock/unlock.
Good luck with that. . .
