Ron, I don't disagree with "in some cases purchasing a TR7A is a buyer beware."
But I must say that IF the TR-7 has had all the modifications that upgrade a TR-7 to a TR-7A, the only remaining significant difference is the use of a '1496 balanced modulator in the 2nd IF/Audio board rather than the diode detector. For all the other changes, Drake supplied the components and installation instructions free of charge. What a company! 73, Tom, AG9X On Thu, Jun 25, 2009 at 9:48 AM, Ron Baker<wb4...@comcast.net> wrote: > Pete, the quick answer to both questions is yes.
