Testing the DX WORLD amp board and comparing it to the 4 x MRF300 VK-AMP board .

here is the link to the vk AMP eBay board Sold to a friend of mine.    • Australian made  mrf300 x 4  amp board sol...   And now here is this video, is the test of just two of the same devices ( mrf300) I pulled these of one of my VK-AMP. Australian boards. As you can see, the Dx world board, in the video, 645 watts out from 7 watts of drive after the attenuator At 53 volts and 15.6 amps for a efficiency 78% Now the 4 x mrf300 , Australian made amp , made 560 watts for 10 watts of drive 27 amps at 48 volts for an efficiency of only 43% If I run two, DX world boards, for 4 devices In total, I would be At 1290 watts At around 31 amps . This is a far cry from even the 780 watts at 28 MHz shown on the Australian board makers you tube Channel . And the, Dx world boards easily makes 660 watts on 28 MHz on just two devices and would Easily make 1320 watts up on 10 mtrs with two boards and 4 x Mrf300, 540 watts more than the Australian made 4 x mrf300 board. Next video will show , harmonics pre filter, imd products and the wave form at 600 watts on the scope . Thanks for watching .
