The 'legal mode' issue keeps coming up everytime a

Walt,
I would rather have ONE mode that is scalable so that you could
merely adjust it according to the demand, speed vs SNR, etc.
Please write to me off-line if you plan to attend HAMCOM in Dallas.

Hi Howard,
It is best to arrange a sked on Digitalradio or HFLINK group.
We have previously used one of the ALE channels at 14346.0kHz USB for
sending images with the 188-110 modem. We link first on ALE, then use
SSB Voice QSO for setting things up. We don't use any texting or chat
via keyboard.
Yes.

Hi Bonnie,
To condense, is your opinion as follows?
It is legal, in the US, for image or voice content on HF in the
image/voice subbands.
It is not legal at all, in the US, in the RTTY/data subbands.

That is false.
The modems are legal on HF for hams in USA.
They may be used for image or voice content on HF.

Hi Rick,
Perhaps you have been confusing "baud" and "symbols per second".
This is a common mistake many hams have with complex digital formats.
To answer your question...

the 110A modem from one company:

Depending upon the BER you can tolerate, it appears that the 2400 bps

I think the first thing is that individuals need to decide what USER

Poor Bonnie!
We are hitting you from both directions:
--some want better weak signal performance at the cost of speed (~HF)
--some want more speed at the cost of signal performance (~10M & VHF)

If the 110A works this well at 2400 baud, what would happen with slower
speeds? From what I understand, it does require a good signal to get
through, perhaps comparable to the WinDRM software at maybe +10 S/N dB
or maybe a bit below that?

Hi John,

Well, MIL-STD-188-110A uses a single phase shifted

The difference between packet and this MIL-STD is just
huge. Interleaver to fight fade and QRM, equalization
