Hans Summers G0UPL of QRP-LABS produces a range of really stunning high quality kits at very modest prices. His current QCX model which is a 5 watt mono-band CW transceiver has sold over 5000 units to date and sells for just $49.
At the YOTA (Youngsters On The Air) construction day last weekend, the participants were building a new 7 MHz SSB and CW 10 watt transceiver from QRP-Labs...pictured above. It's looks as if this kit will be on sale in the near future, possibly the end of 2018.
1) The single band version has a guide price of $75.
2) The plan is to have a 10 band version (10m-160m) for a guide price of $150.
3) It is a SDR based transceiver! As it shows in the slide below, the plan is to have the performance of a high end commercial radio but at 10-20% of the cost.
With the current popularity of FT8, this rig on SSB is likely to be a perfect match with its 10w and high stability.

Update Fri 17th Aug.... http://www.qrp-labs.com/qsx.html
Update Tues 28th Aug... The power amplifier stage reportedly will use two IRF510's in a Push-Pull configuration giving 10 watts across the HF spectrum (2dB variation). The amp is 4dB down at 50 MHz and 8dB down at 70 MHz. This is about 4 watts and 1.5 watts respectively.
Some of the key features...
Software Defined Radio (SDR) technology with standalone Digital Signal Processing (DSP), no PC required
