QST June 2006
Would anyone have a copy of QST June 2006 that they could scan the
article about building a homebrew 600 watt amplifier on page 39 or possibly know of a link where I could download it? Thanks, Rob WB8VWI |

Thanks, Rob WB8VWI the design is a motorola published design. Communications Concepts also sells parts to make it and has the schematic on their site. Allison |

. .. Would anyone have a copy of QST June 2006 that they could scan the article about building a homebrew 600 watt amplifier on page 39 or possibly know of a link where I could download it? Thanks, Rob WB8VWI Rob, IF you desire to build a solid-state RF amplifier -- it will be for education / build desire -- rather an economics (in other words -- a used Ameritron/MFJ ALS-600 (with 4 MOSFETs) is often much cheaper. It is advisable at 500/600 watt and greater -- that 24/28 VDC or 48/50 VDC RF transistors be used -- lighter gauge wire - less amperage from power supplies. Next read all that you can about Helge Granberg, K7ES(sk) -- Finland's version of Art Collins who wrote most of the Application Notes for Motorola that all other designers have used as the baseline for their designs. http://www.communication-concepts.co...tion_notes.htm Amplifier Home building G3TSO (an award winner) http://www.qsl.net/g3tso/HFLinearFrameSet1.html Communication Concepts (supplier of boards referenced in the June 2006 QST article) http://www.communication-concepts.com/ Tom Snowden's 600 watt version -- using the MRF150 RF transistors http://www.k0gkd.com/ssamp.html Pieter Ibelings, N4IP BROADBAND, SOLID STATE AMPLIFIER FOR HF AND 6 METERS http://www.ibelings.com/n4ip/mrf157.html Joel F. Paladino, N6AMG(sk) also had articles on MOSFET design featured in QST and QEX in 1980s (consult back issues) UK design using new power-MOSFETs http://www.picks.force9.co.uk/throb.htm w9gb |

The link to Tom's web site (below) -- will provide not only the article contents but MUCH more than in the QST article ! http://www.k0gkd.com/ssamp.html |
