The spectrum of the F32 CW Modulator was measured by sending the alphabet in 5 character words along with some numbers. This was adequately random to suppress periodic spikes when averaged over a number of FFT. Measurements were done at a...

(sent b4) These are all small enough that I don't plan anything further for time improvement, but there are things that could be done if anyone cares. I will pursue spectrum measurements, yet. Oh, also, I will update the F32 Design Tool. And...

Hi All - just got back from weekend trip and got to the CW modulator. I re-fixed PR 31! Also I removed some unused variables and did the timing tests. At Sample rate = 12 ksps, the update uses 81 uSec which is less than 1% of the available...

Oops, sorry. I'll fix! Bob

Hi All - I had distractions, but did finally get a CW Modulator that runs with sample rates near 12, 24, 48 and 96 ksps. It does not have the efficient interpolation that I was hoping for, but more importantly, it works. I put it up on the...
