Hey Steve: Although I will probably never find it in my storage room, I do have a copy of a letter regarding the version 2 IF board.......I believe it was from Bill Frost, but can't guarantee it..
The point is/was that 2 resistors are changed on another circuit board when using the version 2 IF board.....and, no I don't remember which circuit board..... If anybody has this information, it may solve part of your gain problem. 73's & GL Bill W6FF Santa Barbara, Ca. ================================================================= > ----- Original Message ----- > From: [EMAIL PROTECTED] > To: [email protected] > Sent: Monday, June 09, 2008 10:28 PM > Subject: Re: [drakelist] TR7 2nd IF Audio board: redux and question on > R1136 > > > I have S/N 6951 and it has a version 1 IF board.
