I had a new idea for mine. Which basically works except at night. I have a couple bandpass filters and the software changed to cover all freqs. I'm going to use the low level VFO output as a signal

The readers are probably going to need more info in order to be of some help. While you may have mentioned the issues in an earlier post, most readers would prefer to have the (remaining) issues

Still no worky ...

Set the VFO to 4vpp as mentioned in the article.

Hi Again, 49er still no output (audio) from 49er -- no worky... I've calibrated the DDS VFO frequency to readout accuracy and sending ~2.5V, P-to-P signal to 49er mixer input. I've ordered another

I am building the Forty-9er (VFO is completed) and hit a snag. The PCB shows CP9 as an electrolytic and the schematic shows it as a 0.1uF disc. To make things more confusing, I seem to recall mention

Yep that's the one I mentioned in my original post. I was excited to find out about this group to find someone else that tried this project. When I found code with a later date i jumped at it,
