Received my SRP/NOV today & the DF3LP is the design I am following also but with a IRFP460 from my existing stock, I've just produced a simple PCB using a mini drill with a small burr bit to grind the copper away for solder pads. 73 Gary - G4WGT - IO83qp ----- Original Message ----- From: "Dave G3WCB" Thanks for the reports. I've just upped my power to 10W, which is an estimated 50 mW ERP...erring on the side of caution!. Antenna current is about 300 mA. I bult my PA from bits of a junked PC power supply. A single IRF 540 running from 12V. Very simple, just a scaled-down version of the DF3LP design for 137 kHz 73, Dave G3WCB IO91RM -----End of Original Message-----
