And I didn&#8217;t release any IRF510 smoke. There is, of course, a lot more output on 75 than on 20. That&#8217;s just the nature of the IRF510. I get about 4 watts out on 20 and about 9 watts out on 75 (with a 12 volt supply). At Pete&#8217;s suggestion I might replace the IRF510 with a Mitsubishi RD06HHF1. <\/b><\/span><\/p>\n<p><span style=\"background-color: #f9f9f9; color: #030303; font-family: Roboto, Arial, sans-serif; font-size: 14px; letter-spacing: 0.2px; white-space: pre-wrap;\"><b>I had a couple of minor problems getting the transmitter going.
