WA7MLH's RD16HHF Amplifier


OK, so now that I have the MOXON in the air, my thoughts are turning to amplifiers and a possible winter project. Hey, even QRP guru Doug DeMaw conceded that every once in a while a fellow needs a few more db. And the sunspot count will be dropping.  

On the BITX group there has been an interesting discussion of using RD16HHF MOSFETs in place of our familiar IRF-510s.  I thought these devices were new, but some Googling this morning led me back to the wonderful website of QRP giant (hey, he is IN SSDRA!) Jeff Damm,  WA7MLH.   Jeff has been using these devices for quite some time.  As with all of Jeff's projects, I find his EXTREME UGLY building methods to be inspirational and reassuring.  Even if you have been there before, you should visit his site:


Even his QRZ.com page makes you want to build something:

Thanks Jeff!
