Thanks to those that helped on this situation, got it all goin now.

 It came down to a SWR/OHM. I re-installed a new coax and roof mount, SWR now is 1.0 ch16-28 with 47ohm (according to the mfj269). That 1/2-3/4W carrier  from the radio is now an 85W carrier, and the 6-8 W PEP from the radio, is now 450W on the dx500.  Great to know the amp is just cruising at those numbers. 


By the way, nothing was/is wrong with the mod v. It was off also because of the SWR/OHM. It now shows 20w carrier and 80w PEP, from the 1/2w radio carrier  to 7w radio PEP (WHICH IS NOT IN LUNE ANYMORE). its on my washington, doing fine.
