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.
