Please see latest production status info at the end of this thread.

I received 5 prototypes three days ago (Oct 7) built by MacroFab. They work fine. I'm in the middle of characterizing them. The photo below lists most of the new hardware features (click for larger).

Some of the prototypes will be sent to beta testers who have exceptional reception and can split an RX antenna between a Kiwi-1 and Kiwi-2 so we can do some A/B comparisons. We should also have samples of the new enclosure soon.

Your signal (recorded), from my latest standalone version (not merged into Kiwi extension yet) with more decoding:

Others (from recordings people sent me), including a DTM:

These are from a recent attempt to make a "user preferences" function work. They are required by xdLocalStorage. I tried again about 6 months ago with xdLocalStorage. More recent browser security changes mean the scheme had to be changed once again compared to work that was done some years ago. It quickly got complicated, so I had to set the work aside for the moment.

For those that don't know, user preferences would be an extension that allows you, an ordinary Kiwi user (not owner/admin), to do things like: Setting the default cw passband set to 270 Hz and have that apply to every single Kiwi you ever visit from that point onward. Or the same with keyboard shortcut bindings. Or just about any other user interface customization that could be easily added.

That, plus a real mobile user interface, are the two major missing elements of the software (besides adding an extension to decode your favorite modulation waveform).

From an hp 8657D coupled with a "gimmick" cap. No front panel sweep on the "D" unfortunately (HPIB only). So manual 10 kHz steps. Kiwi spectrum averaging and peak function to capture. Except for < 150 kHz where there is a clear drop-off, the scalloping is probably FFT spectral leakage since I never learned how to do my post-FFT DSP properly.

I see SMPS harmonics that are much louder than the fundamental all the time. Even into HF sometimes. It just baffles me. And when the fundamental is an unstable carrier, at HF it often turns into such a wide signal that the harmonics bridge together and it looks like a huge bump in the noise floor!
