Dear AP2MU

Thanks for the appreciation.

Actually this project belong to Taiwan Radio Amateur and I had that project on my visit to Taiwan in 2004 .

On my request and interest they arranged a sample unit .

That unit was tested by AP2RP and further GSY to AP2SDO.

AP2RP tested that unit and he was quite satisfied with its size and performance.

The sample unit was delivering 600 ~ 700 W ( Carrier ) that we tested in AP2RP shack.

The only drawback that I felt with such kind of amplifier is the current requirement that is at least 70A @ 13.8V DC on full power out.

Any how one can manage it at 300W @ 13.8VDC 35~40A

I requested my friend to prepare a sample unit for AGM 2010 so that our valued members can experience that project .

Currently the availability of this project can only be possible in 3 ways.

1) Non Assembled unit in Kit form including A to Z parts .
2) Assembled and tested unit
3) PCB only
