QCX-mini: a feature-packed, high performance, single-band 5W CW transceiver kit, with WSPR beacon and built-in alignment/test equipment. Available for 160, 80, 60, 40, 30, 20 or 17m bands. It has rotary encoder synthesised tuning, VFO A/B/Split, Iambic keyer, CW decoder, and more...
The QCX-Mini is CW only. Voice (SSB) is more involved but I'm sure people make kits for that as well. CW requires much less power to reach the same distance as voice, which is why it's popular for DIYers.
The one I built uses crystals, so you get the frequency of the crystal. Technically it has a little bit of an offset so you get two frequencies about 500 Hz apart. If you look closely at my pics, you'll see two of these. One is for the TX circuit and the other is for the RX circuit. I'm using 7.040 MHz.
