Bodin" <[email protected]>; Date: Thu, 28 Jun 2007 22:22:54 +0200; Dear Jim, it would be very interesting to have a look at your TX design. Attached is a schematic of a push-pull class E amplifier. I have had good results with such a circuit at QRP levels on 80 and; /rsgb_lf_group-archives/html/rsgb_lf_group/2007-06/msg00068.html (9,388 bytes)
