The first is by Rien, PA0TRT from Feb. 2004. A second is from July 2005 when he refined the circuit. http://home.wanadoo.nl/cmulder/drake.htm#bookmark4 There is also a board available for the circuit designed by HB9ABO which appeared in "BETTER FREQUENCY STABILITY FOR DRAKE TR7" in the August 1987 issue of Ham Radio magazine. Far Circuits lists the board for $8.00 and a reprint of the construction article is $1.50. The only issues may be parts availability and postage. http://www.farcircuits.net/ -Tom, AG9X On Sun, Jul 20, 2008 at 12:43 PM, John Stringer <[EMAIL PROTECTED]> wrote: > "John Stringer" <[EMAIL PROTECTED]> made an utterance to the drakelist gang > ---------------------------------------------------------------------- > I read somewhere that a board is available to improve PTO stability.
