For CW you need a tunable VFO and this is not easy with reasonable stability
You wiull have to use an HF transceiver as a tunable IF

Hello,

I'm trying to find some simple receiver (or at least a converter)
project for 440 or 144 MHz to build. I'm interested in CW mode. But
there's nothing.
Is it very hard to build something for 70 cm or there are another
reasons, that I can't find anything?
