how about a PLL or DDS (tuneable in selectable 1hz/1khz/5khz steps) 1 watt (Class E? / 50 ohm output) lowfer tx (or Tranceiver) that does CW/AM/SSB?
it would be neat to have for CW or Voice Comms on longwave.
maybe some of the geniuses on here can get together and cook up a project like this.
i realize it would be a complex circuit, but it would go a long way to bring the longwave band to life.

What about an AM Radio station on LW between 160-190 Khz. I've also had an interest in the part 15 SW and doing a Radio station. Especially if it would skywave.

perhaps the tompolk PLL would be viable with a trimmer to fine tune? i've seen a few PLL's that can work from .1-10mhz
