Looking for the model 248 noise blanker board for my Omni D. Is there any chance it is the same board as used in the Triton IV, 540, 544 or did they go to a different board in the Omni series rigs.? Appreciate an email, I may have a source for one out of the earlier Triton IVs but not sure it will work. Thank , 73 Jim N0XE
