Superb HF LDMOS 1200W HF KIT w internal power supply			Time Owned: 6 to 12 months.
This short review will be from a user perspective. I have done an extensive search for the best in class solid state LDMOS (not FET) amplifier KIT and I believe i found it. The KIT build was absolutely easy! Worked the first time around with no issues. I had set aside a weekend to build the amp but to my pleasant surprise I finished it in about 4 hrs! Kenny supplies you with a video file where he tests the amp before he ships it to you. He provides video proof it is your amp. You have to supply two pieces of coax and a nano board which I found on Amazon for less than $10.00! He supplies all the instructions and firmware you will need. You will end up soldering a few wires (power, coax) and the rest is installing a few modules. No components like SMDs require soldering, This latest revision works from 160M through 6M! Operation: With just abt 18W input power I get about 1000W. Lost of protection. I updated the display once and all I had to do was take the top cover off, insert a microSD on the top right hand side of the display and turn the unit on. It updated the display automatically. Guys don't be fooled by name brands. Kenny gives you a lot of amplifier for the money you spend .because he builds it and tests it himself from beginning to end. Comparable amps in power output will run you a lot more money and they are usually running FETS. This runs the latest in LDMOS technology. Kenny will back the amp 100%. If you run 1200W vs 1500W I’m confident you will not notice the difference and bottom line legal limit LDMOS solid state amps are running in the $4K+ range!!! Cosmetics are beautiful. Contact Kenny and he will email you some pics of the inside.
