I get 7w with a class E NS40 by 4sqrp. Apart from the layout of the board, a real masterpiece, it is amazing that just after key down the final remains that cold (very mild temp). My other twofer qrp by Hendricks with just 1w the final notwithstanding is biased correctly is hot. Thumbs up for class E... a pity there is no commercial class E amplifier as far as I now.

Jack, I'm getting about 4 watts output with 13.8v the way I have it currently configured. It's driven with a 2n7000 MOSFET. I'm wondering if the uBiTX could benefit from this because it requires lower drive levels from the LO.?
Dan? W2DLC?
