Well, the only implementation so far is floating-point. I suspect the fixed-point performance would be a lot better if we ever get that written. It can keep up with real-time on a Raspberry Pi or an old Atom laptop.

Correct me if I am wrong, but the technology we are talking about here is merely splicing some reconstucted sequences into existing human cells.

You don't have to synthesize the entire cell. Only the nuclear and mitochondrial chromosomes matter. If you can replace the ones in a normal cell, what you have after division is the primitive cell reborn. You have to do this to a lot of cells, and grow them for a while, to get one without significant damage.

* Anything but FLAC and Codec2 (because FLAC doesn't compress and Codec2 is voice-only and ultra-low-bandwidth).

We can definitely see SSB on our waterfall. And it interferes with us somewhat. This isn't like the ultra-narrow slow digital modes like WSPR or PSK31 where you might not have to care about another station on the frequency. So, I think our operators would generally avoid it.

I have a surface mount workstation at home. I've been cheering on Chris Testa, whose mobile SDR design is mostly surface mount. He did run into problems with a module socket that was awful to solder.

Oops. Thanks for the typo.

We have had other spread-spectrum rule-makings lately. If you want to experiment with it on HF you should apply for a Special Testing Authority. The problem is, as you obviously already know, getting the existing HF operators to live with it. I didn't specifically address SS, but the bands with wide bandwidth or "Not Specified" can obviously handle it. I thought the document was ambitious enough without talking about spread spectrum.

CSMA doesn't work that well on HF. Sometimes you should be able to share a frequency with distant operators even though they fade in and out, etc. However, it makes sense if you are doing automatic link establishment.

Hi Roscoe,

I want to have my opinions heard. And having notoriety helps. So I do not shy from self-promotion. But the point here is to get people interested in what I wrote, rather than just me.

It might be different if the purpose was just to sell my stuff. This is a non-profit activity.
