It sounds a bit wobbly, but it's a good start.
The next step is to put together a little DDS oscillator small enough to be mounted internally. I'm not sure if I should try one with multi channels or just make separate ones to replace crystals.
I've now got it receiving 40m quite well using a DDS VFO with programmable offset that I purchased on ebay last year and badly boxed up.
Tip: You power it on while holding the CAL button to set the offset.
