Hi Ed, The differences I see between the -25 and -26 are minor. Caps and resistors in the Low Pass Filter audio stage and a different 12.8Mhz reference with a voltage tuning pin, where the standard didn't have it. The specifications of the reference are same otherwise, 1ppm -20 to +70. If you are going from -25 or -26 to -20, just change the components to the -20 values. Yes, they were defined changes for FCC, according to the book.
